One my first computers was a radio shack – it had 4k memory. Space invaders was the first “cool” video game (course there was pong).
Still remember cpm-80 operating system along with ms-dos being the two choices. Word processing was done with disks that were about 10 inches high (not 5 1/4′).
How about supercalc 123 – before lotus 123.
Anyone remember the Sinclair. It was fast and cheap.
When I was in College, we did programs using code punched out on cards – then put the cards in order – and ran them through the computer ( a really huge floor model).
