<
p>EXORsim simulates a Motorola EXORciser, which was a development system that Motorola sold in the late 1970s and early 1980s for the 8-bit 6800 microprocessor. Some pictures of this development system can be found at Pekka Tanskanen's website here.
<
p>EXORsim also simulates a SWTPC 6800 Computer System, which allows you to run the TSC FLEX operating system.
EXORsim now emulates an EXORterm! I was finally able to find manuals for the EXORterm 155, so I've implemented an emulator for it. This allows the EDITORM Resident Editor to operate in screen mode.
<
p>The EXORterm emulator operates as a filter between the EXORciser and the user's ANSI terminal emulator (such as XTerm). This allows you to use terminal emulator features such as scroll-back. I find this to be more useful than some emulators which run under MS-Windows, but provide only a very rudimentary terimnal.
<
p>EXORsim provides these features:
Just type "make" to compile it:
exor This is the simulator
mdos This provides file access to MDOS diskette images
unasm This is a stand-alone 6800 disassember
Right now the exbug.bin and swtbug.bin files must be in the current directory.
To run the simulator:
./exor mdos.dsk
You can get MDOS disk images here:
ftp://bitsavers.informatik.uni-stuttgart.de/bits/Motorola/mdos/
You need to use "ImageDisk" to extract the binary data from from the .IMD files.
imdu disk.imd disk.dsk /b
You can get ImageDisk from here:

To run FLEX2:
./exor --swtpc flex2.dsk
You can get FLEX2 disk images here:

Download the "FULL kit", install it and find the FLEX2 .DSK files.
