This is just the MC6800 assembly code from
the bitsavers archive of the Micro-Chroma-68
It is called "TV-Bug" and was created in 1978
for experimenting with the Motorola MC6847 VDG.

I have tested it to compile using the "AS0.exe"
from the simtel archive using DOSBOX.
( Link is below, the tool is in the MotoASMS.ZIP
of Simtel-MSDOS-Sep1996-CD2.iso , in directory:
E:\DISC2\CROSSASM\MOTOASMS.ZIP )
