Introduction

Einstein Platform is a way to transform a computer in a next-generation Newton N2 (MP2x00, eMate 300). Einstein is a project to unchain NewtonOS from existing hardware. More information can be found on the Einstein Project home page: http://kallisys.com/newton/einstein/ and on the OpenEinstein page on Google Code: http://code.google.com/p/einstein/

Requirements

Einstein Platform currently runs on the following machines: Einstein Platform requires about 40 MB of storage. Instructions about how to extract the ROM are available in the next section. PLEASE DO NOT ASK ME FOR A ROM FILE. I will not provide you with any. NewtonOS ROM is copyright by Apple Computer, Inc and licensors.

Extraction of the ROM from your Newton

Two methods are available: via a serial line or via TCP/IP (i.e. via an Ethernet access).

Hammer/Newtsbug (serial line)

Using a low-level debugger such as Hammer or Newtsbug, you can make a dump of the memory. This is slow and works over the serial line.

Requirements:

Steps:

A standard get file dialog appears: choose the debugging image corresponding to your Newton (Senior CirrusNoDebug image, Senior DCirrusNoDebug image or Newt KNoDebug image for the MP2x00 US, MP2100 or eMate 300 respectively). Wait.

ROM Dumper (TCP/IP)

ROM Dumper is a faster approach but requires an internet connection between your Mac (or any Unix computer) and your Newton.

Requirements

Steps:

The platform will be configured to use the newly dumped ROM.

Alternatively, you can use nc(1) command line tool.

Einstein on MacOS X

Just copy the GUI application to your hard drive and double click it. The first time, it will ask you to tell it where the ROM image is.

You can run Einstein Platform full screen. To exit Einstein, go to the Extras Drawer, tap the [i] button and then choose Quit Einstein.

On MacOS X, Einstein application is scriptable. You can install packages or evaluate NewtonScript code within Einstein Platform using AppleScript.

Using the CLI flavor on MacOS X

On desktop computers, the CLI flavor should mainly be used to access the log and/or the monitor mode. It is therefore intended for developers.

where XXXX should be either: 717006 (for a MP2x00 US) 737041 (for a MP2100 D) 747129 (for an eMate 300)

Options

./einstein --help will print some help about the options. The options are summarized below:

--audio or -a

Select the audio driver (null, portaudio or coreaudio). --audio=null will disable sound. --audio=portaudio will choose portaudio sound driver. Default is coreaudio.

--width

Set the width of the screen (in portrait mode). Default is 320.

--height

Set the height of the screen (in portrait mode). Default is 480.

--log or -l

Set the log file. Default is to not log. This option is incompatible with --monitor.

--machine or -m

Set the machine. Choose 717006 for a MP2x00 US, 737041 for a MP2100D or 747129 for an eMate 300. --machine option can be omitted with a 717006 ROM file.

--monitor

Run in monitor mode.

--ram

Set the RAM size in 64 KB increment. 1 will mean 64 KB of RAM. 64 is the default setting (4 MB). The maximum is 255 (nearly 16 MB).

Einstein on arm-linux PDAs

Quickstart on the Zaurus

I used a Zaurus SL-5500 (thanks Sylvain) with OpenZaurus (http://www.openzaurus.org/) 3.5.4-rc ROM and the following packages:

Any more recent version of OpenZaurus and these packages should do it.

I first installed the Bootstrap Image with the zImage-64-0 to have enough RAM for Einstein Platform. Then, I copied all these packages to a CF card and I installed them all at once with the ipkg command line tool on the Zaurus (with something like ipkg install /mnt/cf/*.ipk).

Then, I copied the three elements from the release archive as well as the 710006 ROM image to the root of the CF card. And I launched the script with: /mnt/cf/start-einstein.sh.

More details for other PDAs

Please note that Einstein Platform requires quite a large amount of RAM. Most old PDAs do not provide enough RAM for third party application unless you enter some developer mode or install a bootstrap image.

where XXXX should be either: 717006 (for a MP2x00 US) 737041 (for a MP2100 D) 747129 (for an eMate 300) and YYYY and ZZZZ should be set properly.

Options

./einstein --helpwill print some help about the options. The options are summarized below:

--width

Set the width of the screen (in portrait mode). Default is 320.

--height

Set the height of the screen (in portrait mode). Default is 480.

--log or -l

Set the log file. Default is to not log. This option is incompatible with --monitor.

--machine or -m

Set the machine. Choose 717006 for a MP2x00 US, 737041 for a MP2100D or 747129 for an eMate 300. --machine option can be omitted with a 717006 ROM file.

--monitor

Run in monitor mode.

--ram

Set the RAM size in 64 KB increment. 1 will mean 64 KB of RAM. 64 is the default setting (4 MB). The maximum is 255 (nearly 16 MB).

Developer Notes

Compiling and porting Einstein

The documentation for obtaining the source code of Einstein, compiling it and porting it is available on Google Code web page: http://code.google.com/p/einstein/

CLI commands

The command line interface is intended for developers and hackers. Using the cli flavor, you will be provided with a prompt. Typing help will provide a small help about the available commands.

Monitor mode

The monitor mode uses a disassembler from the NetBSD project (the kernel disassembler for the arm32 port). You start in monitor mode by specifying the --monitor option to the command line program.

The monitor mode can be considered as an enhanced low-level debugger. The help command displays a short help for the available commands.

One of the main advantage of the monitor is that you can set breakpoints. You can also halt the emulator by calling the Einstein:BreakInMonitor global function (it doesn't take any parameter).

The following breakpoints are enabled by default:

You cannot use --log option with --monitor because in monitor mode, the log is always enabled. You can save the log to a file (it scrolls on the monitor screen). The monitor mode uses a file with symbols. This file should be named after the ROM file, e.g. 717006.symbols. The syntax is:

address <tab> symbol <tab> comment

Addresses should be sorted.

This file is very easy to generate from the debugger images that are used with Hammer and Newtsbug. Use Newton C++ Tools DumpAIF program with the -s option to dump the list of symbols. Then you can process all the lines with search and replace or sed or awk at your convenience. The symbols can be unmangled with Unmangle tool coming with MPW.

Logging

Quite a large amount of log lines are generated by Einstein. These are used during the development of Einstein emulator. It also helps to understand whatÕs going on. Starting with UP2 release, you can generate log lines from NewtonScript calling the |Einstein:Log| global function.

E.g.:

|Einstein:Log|("Hello World")

will display Hello World in the log. If log is disabled, the string will be output on stdout. Please note that your string is converted to ISO-8859-1 before being printed, so non latin characters will not be printed properly in the log.

Relativity Developer Guide

Introduction

Relativity is a new technology embedded into Einstein to allow packages for Einstein to take advantage of host APIs. Relativity can only be used through NewtonScript for the moment. To use relativity, you need to call OpenNativeLibrary NewtonScript function to open a library from the host system.

OpenNativeLibrary(libraryName)

libraryName is a string representing the name of the library to open. Valid names include "libc" or "libGL".

This function returns a library object and throws an exception if an error occurs (for example if the library cannot be found).

libraryObject:GetFunction(functionSpecs)

is a frame describing the function to import. This frame has three required slots:

This function returns a NewtonScript function you can call. The types can be the following:

Some types are illegal for return or argument types (for example, you cannot use iostring for the return type, use string instead). Then, you can call the function naturally by providing Newton data. The result is returned in the form of Newton data.

Once you are done, you can close the library with the :Close() method.

libraryObject:Close()

Close the library. The library object can no longer be used afterwards.

Sample code

In this section, we will describe how to call a simple function, gethostname, that returns the (network) name of the host. The manual page of gethostname provides the necessary information to call the routine.


GETHOSTNAME(3)         BSD Library Functions Manual         GETHOSTNAME(3) 

NAME 
    gethostname, sethostname -- get/set name of current host
    
LIBRARY 
    Standard C Library (libc, -lc)
    
SYNOPSIS 
    #include 
    
    int 
    gethostname(char *name, size_t namelen);

This page shows that gethostname is in the libc library. It also provides the type of the arguments and of the result. The following code calls the function and returns the result.


begin 
    // Open the native library. 
    local libc := OpenNativeLibrary("libc"); 
    // Define the function. 
    local gethostnameFn := libc:GetFunction({ 
        name: "gethostname", 
        args: ['iostring, 'sint32], 
        result: 'sint32});
    
    // Allocate a buffer to store the hostname. 
    // This buffer is a string of 127 unicode characters (+ null). 
    local theBuffer := MakeBinary('string, 256); 
    // Call the function. 
    local theResult := call gethostnameFn with (theBuffer, 127); 
    
    // Close the library. 
    libc:Close(); 
    
    // Determine the outcome of the call. 
    if (theResult = 0) then 
        // Success. 
        return theBuffer; 
    else 
        // Failure 
        return "gethostname failed"; 
end;

    GNU GENERAL PUBLIC LICENSE
        Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

    Preamble 

  The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free 
software--to make sure the software is free for all its users. This 
General Public License applies to most of the Free Software 
Foundation's software and to any other program whose authors commit to 
using it. (Some other Free Software Foundation software is covered by 
the GNU Lesser General Public License instead.) You can apply it to 
your programs, too. 

  When we speak of free software, we are referring to freedom, not 
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for 
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it 
in new free programs; and that you know you can do these things. 

  To protect your rights, we need to make restrictions that forbid 
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it. 

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights. 

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software. 

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original 
authors' reputations. 

  Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
  
  The precise terms and conditions for copying, distribution and
modification follow.

    GNU GENERAL PUBLIC LICENSE 
  TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  
  0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the
Program is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program). 
Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the 
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.
    
    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License. 
    
    c) If the modified program normally reads commands interactively 
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an 
    announcement including an appropriate copyright notice and a 
    notice that there is no warranty (or else, saying that you provide 
    a warranty) and that users may redistribute the program under 
    these conditions, and telling the user how to view a copy of this
    License. (Exception: if the Program itself is interactive but 
    does not normally print such an announcement, your work based on 
    the Program is not required to print an announcement.) 
    
These requirements apply to the modified work as a whole. If 
identifiable sections of that work are not derived from the Program, 
and can be reasonably considered independent and separate works in 
themselves, then this License, and its terms, do not apply to those 
sections when you distribute them as separate works. But when you 
distribute the same sections as part of a whole which is a work based 
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the 
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest 
your rights to work written entirely by you; rather, the intent is to 
exercise the right to control the distribution of derivative or 
collective works based on the Program. 

In addition, mere aggregation of another work not based on the Program 
with the Program (or with a work based on the Program) on a volume of 
a storage or distribution medium does not bring the other work under 
the scope of this License. 

  3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of 
Sections 1 and 2 above provided that you also do one of the following: 

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections 
    1 and 2 above on a medium customarily used for software interchange; or,
    
    b) Accompany it with a written offer, valid for at least three 
    years, to give any third party, for a charge no more than your 
    cost of physically performing source distribution, a complete 
    machine-readable copy of the corresponding source code, to be 
    distributed under the terms of Sections 1 and 2 above on a medium 
    customarily used for software interchange; or, 
    
    c) Accompany it with the information you received as to the offer 
    to distribute corresponding source code. (This alternative is 
    allowed only for noncommercial distribution and only if you 
    received the program in object code or executable form with such 
    an offer, in accord with Subsection b above.) 
    
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable. 

If distribution of executable or object code is made by offering 
access to copy from a designated place, then offering equivalent 
access to copy the source code from the same place counts as 
distribution of the source code, even though third parties are not 
compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program 
except as expressly provided under this License. Any attempt 
otherwise to copy, modify, sublicense or distribute the Program is 
void, and will automatically terminate your rights under this License. 
However, parties who have received copies, or rights, from you under 
this License will not have their licenses terminated so long as such 
parties remain in full compliance. 

  5. You are not required to accept this License, since you have not 
signed it. However, nothing else grants you permission to modify or 
distribute the Program or its derivative works. These actions are 
prohibited by law if you do not accept this License. Therefore, by 
modifying or distributing the Program (or any work based on the 
Program), you indicate your acceptance of this License to do so, and 
all its terms and conditions for copying, distributing or modifying 
the Program or works based on it. 

  6. Each time you redistribute the Program (or any work based on the 
Program), the recipient automatically receives a license from the 
original licensor to copy, distribute or modify the Program subject to 
these terms and conditions. You may not impose any further 
restrictions on the recipients' exercise of the rights granted herein. 
You are not responsible for enforcing compliance by third parties to 
this License. 

  7. If, as a consequence of a court judgment or allegation of patent 
infringement or for any other reason (not limited to patent issues), 
conditions are imposed on you (whether by court order, agreement or 
otherwise) that contradict the conditions of this License, they do not 
excuse you from the conditions of this License. If you cannot 
distribute so as to satisfy simultaneously your obligations under this 
License and any other pertinent obligations, then as a consequence you 
may not distribute the Program at all. For example, if a patent 
license would not permit royalty-free redistribution of the Program by 
all those who receive copies directly or indirectly through you, then 
the only way you could satisfy both it and this License would be to 
refrain entirely from distribution of the Program. 

If any portion of this section is held invalid or unenforceable under 
any particular circumstance, the balance of the section is intended to 
apply and the section as a whole is intended to apply in other 
circumstances. 

It is not the purpose of this section to induce you to infringe any 
patents or other property right claims or to contest validity of any 
such claims; this section has the sole purpose of protecting the 
integrity of the free software distribution system, which is 
implemented by public license practices. Many people have made 
generous contributions to the wide range of software distributed 
through that system in reliance on consistent application of that 
system; it is up to the author/donor to decide if he or she is willing 
to distribute software through any other system and a licensee cannot 
impose that choice. 

This section is intended to make thoroughly clear what is believed to 
be a consequence of the rest of this License. 

  8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License. 

  9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns. 

Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any 
later version", you have the option of following the terms and conditions 
either of that version or of any later version published by the Free 
Software Foundation. If the Program does not specify a version number of 
this License, you may choose any version ever published by the Free Software 
Foundation. 

  10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

    NO WARRANTY 

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION. 

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

    END OF TERMS AND CONDITIONS
    
    How to Apply These Terms to Your New Programs
    
  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    <one line of programmer's name and a brief ideaof what it does>
    Copyright (C) <year> <name of author>

    This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version. 
    
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
    GNU General Public License for more details. 
    
    You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 
    
Also add information on how to contact you by electronic and paper mail. 

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode: 

    Gnomovision version 69, Copyright (C) year name of author 
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
    
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
  `Gnomovision' (which makes passes at compilers) written by James Hacker.
  
  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice 
  
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.
