Ohio Scientific Superboard II
In 1978 (or thereabouts), when I was in college, my dad bought this computer. It was made by Ohio Scientific and is a Superboard II, a.k.a., model 600 single-board computer. It came by default with 4k of RAM but dad knew that he’d need more than that so he doubled it to 8k. He initially built a power supply for it but the power wasn’t clean enough so he bought one. The computer was connected to a small black-and-white television set and a portable cassette player for program and data storage. I actually did more BASIC programming on this machine than on any subsequent computer I’ve owned, moving on to Pascal in 1984 when I bought my own NEC computer. Although this was the family’s first computer, Ralph had one sooner. I believe he bought it with a friend at school and it was a more powerful thing, using an Intel 8008 processor, if I remember correctly.
