Or how about the Ohio Scientific C1P with 8K RAM, NO display, or disc drive with memory retention on a audio cassette player. Always booted into BASIC.
I remember seeing advertisements for it, but I never had enough money in those years to buy something like that. I know I wanted one.
I had to settle for the Quest "Super Elf." It took me awhile to save up the $100.00 it cost to buy it back in 1977.
