TRS-80, was Re: Puzzling stuff at the end of standard QSTRUP

FWIW, my Mod I is still packed up in as tightly sealed a box as I was able to manage. 2 floppy drives, double-density kit, figured out a way to get the screen printer to work with TRSDOS running (heavily modified expansion interface interconnect cable, and a custom cable that plugged into the second audio cassette socket, and used the motor-on signal [which coincided with a suspension of the interrupt that was interfering with the screen printer's access to the video memory] to trip the screen printer.

Also had the 4" mini-plotter that was sold as a CoCo accessory. Wrote a demo program for it, that included the classic Trichotometric Indicator Support.

But we probably had all better shut up before The Powers That Be yell at us for flying off-topic.
