And does anybody remember the Doctor DX cartridge for the Commodore 64
from AEA? That was an amazing piece of work. I used one to train for a
trip to J6 for CQWW CW in 1991.

Don't forget how revolutionary the Commodore VIC-20 was with all of
3.2 K of RAM. We (Microlog) made a plug in called the AIR-1 for the
VIC that allowed CW & RTTY communications. I wrote a complete
production test program in BASIC that required no other test equipment
but plugging in the AIR-1 and running the tape loaded test program.
It checked the CW copy, aligned the AFSK generator and verified CW &
PTT keying, all in that 3.2 K of RAM with neat graphic indicators on
the screen for the production testers.
