Installation of the Atari 800 Emulator
--------------------------------------
Irrespective of whether you are going to compile the emulator yourself
or install a pre-compiled binary version you must obtain a copy of the
Operating System ROMs.
The ROM images are distributed within the PC Xformer 2.5 package (other
versions of this program do not contain the ROMs in a suitable format)
which can be downloaded from:-
http://www.signus.demon.co.uk/david/atari/atari.html
If you are creating the ROM images yourself they should be copied from
the following locations:-
1. Atari Basic (8192 bytes between $a000 and $bfff)
2. Atari OS/A (10240 bytes between $d800 and $ffff)
3. Atari OS/B (10240 bytes between $d800 and $ffff)
4. Atari XL/XE (16384 bytes between $c000 and $ffff)
5. Atari 5200 (2048 bytes between $f800 and $ffff)
Note: If you are extracting the atarixl.rom you will find that the
ROM area under the custom chip ($d000 to $d7ff) are mapped
between $5000 and $57ff when bit 7 of PORTB is set to 1.
i.e. You should set bit 7 of PORTB and then dump the memory
out in the following order:- $c000 to $cfff, $5000 to $57ff
and finally $d800 to $ffff.
The first time you run the emulator you will be prompted for the
location of the ROMs and various other defaults. If you want to
change any of these in the future simply start the emulator with
the "-configure" command line option.
Compiling the Emulator
----------------------
The emulator can be compiled for the following systems (and probably
many others with a little work):-
1. X Window Version (Including SUN OpenWindows) on a Unix Platform
2. SVGALIB Version on Linux
3. CURSES version for UNIX
4. Graphical Version for the Amiga
5. BASIC version (No Graphics). Should be straightforward to configure
for any 32 bit environment supporting ANSI C.
6. VGA Version for DOS
Note: I don't say 32 bit computer because certain operating systems
enforce a 16 bit memory model. No prizes are offered for correctly
identifing the OS in question.
Building the Emulator on a Unix Platform
----------------------------------------
1. Type "make" for a list of supported platforms.
2. Select the most appropriate platform and type "make <platform>"
for instance if you want the linux svgalib version you would type
"make linux-svgalib"
3. Install the emulator by typing "make install". If you are building
one of the linux svgalib versions then you should login as root
and type "make install-svgalib" this is because svgalib programs
need to be run setuid root.
Building the Emulator for Curses
--------------------------------
Follow the instruction for Unix but note that you must be using the
System V Curses Library. BSD Curses is lacking a few functions and
will not work (nodelay, attron, attroff, keypad and curs_set).
Building the Emulator for VAX/VMS
---------------------------------
This version only support the BASIC text only mode. You will be
able to run programs such as:- DOS 2.5, DOS XL, MAC65 (disk version),
Atari Basic and similar programs. I have had reports that you can
make the X11 version run under DEC-Windows with a little work.
Note: I have not built this version for a while. Modifications may be
required to vmsbuild.
To build type @vmsbuild at the command line. I have compiled it with
GNU C 2.6.1 but I don't expect problems with other versions. It
will probably compile OK on VAX C but it will require the appropriate
compilation options to be inserted into vmsbuild.com
atari800 :== $DISK$xxxx:[yyyy]atari800.exe
where xxxx is the disk the software is on.
yyyy is the directory the software is in.
Building the Emulator for the CBM Amiga
---------------------------------------
Compiler: GNU C + DICE C (Lattice C Untried)
There is a separate makefile provided for the Amiga - Makefile.amiga
By default it is setup for use with GCC. If you are using Dice C you
will need to comment out the GCC section and remove the comments from
the Dice section. Unfortunately I don't use DICE C very often so if
it no longer compiles please let me know.
GNU C is available on AMINET under dev/gcc but needs about 6MB to
compile the emulator.
For GCC be sure that the C_INCLUDE_PATH environment variable is
pointing to the location of the official Commodore include files
prior to compiling the emulator.
For example:
setenv C_INCLUDE_PATH /path/of/cbm/includes
Building the Emulator for DOS
-----------------------------
To compile, use DJGPP the DOS port of gcc, which can be get from
http://www.delorie.com/djgpp/. You don't need any contrib libraries.
A basic setup will do. (I haven't tested the EZ-DJGPP distribution,
but I suppose that's all you need).
If you have GCC, the second thing to do is rename Makefile to Makefile.org
and Makefile.dos to Makefile. Now type "make vga", answer the questions
required by "configure" and wait for gcc to build atari800.exe. To run
this binary, you'll need to set the following environment variables:
Also, if you run it in DOS mode and you have not installed DJGPP, but you
want to run the binary files, you'll need to install CWSDPMI by
typing cwsdpmi -p. To unload cpsdmi, type cwsdpmi -u.
