The IBM 5100, definitely a desktop (check out the pictures of these), which did basic and APL was out in 1975.

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….
