[Elecraft] Computers in the Stone Age

And Metrovision (in the Washington DC area), the first licensed ATV 
repeater, had a Mark-8 (an 8008) at the repeater site in 1974.  We could 
program it remotely using keyboards (in raw octal machine language), and the 
results came back via a character generator on the video downlink.

Nah.  Heathkit H89 came out in 1979.  “All-in-One” desktop computer. Z-80 
processor. CP/M OS addressed 64 KB and used 39 kb of that total. two 5” 
floppy drives (dual sided 800k) as an option. Later, somebody came up with a 
card that plugged into the 5” drive slot and gave 128K of silicon hard 
drive. Now THAT was advanced for its era. Booting from that was faster than 
lightning, for its time.

And do not forget the Ohio Scientific Instruments OSI Challenger 4P….
