[sebhc] using the game files

Eric was interested in getting files into a form that you could execute off
a floppy. HUG distributed a suite of programs I wrote for HDOS to load in
tapes, store them in files, and then run them later. I remember calling the
file format "TMI" (for Tape Memory Image). As Scott pointed out, it's
"rude" to do hardware I/O under an operating system .. my run program took
care of that by completely restoring the state of a pristinely-loaded tape
before executing it (making it as if HDOS was never there). Does anyone
have that package?
The hex dumps (and raw binaries) of these games do not contain the initial
PC value that is normally stored on tape. Luckily, all the original Heath
stuff starts executing at the load point, 040.100 (0x2040).
Mark wanted to try these on the emulator .. to simplify that I converted
them to the .PID (AKA .tape) format the emulator uses. I uploaded those to
the ftp area. By the way .. does anything besides the emulator use that
format?
These are the software issue versions of those games (note that H8HANGM.xxx
is the same software product as the HANGMAN.PID previously posted):
HANGMAN ISSUE # 20.00.00.
CRAPS ISSUE # 21.00.00.
NIM ISSUE # 22.00.00.
HEXAPAWN ISSUE # 23.00.00.
And Scott - I'll have to dig around a bit, but I know I have the .ABS format
somewhere.
