I don't have any of the s/ware now but I used CHIP-8 about 1980 on a
DREAM (don't ask me what that stood for).  It used a motorola 6802
processor and used cheap video. ie. the processor was used in
generating the video signal so that the machine went faster if you
turned off the display.  I built it from an Australian kit.

The magazine that published the design "Electronics Australia"
printed several games for the machine and an alarm clock.  Some
contained machine code but if you have access to 10 year old copies
of the magazine I am sure there would be something interesting there.

This may not be helpful but I had to reply when I saw somebody
mention CHIP-8.  Happy memories.
