I however wire-wrapped it and used some 8x8kBit (or 2x8K) memory. Did add some extensions but never got to an eprom or cassette player extension. So every time I played with it, it was binary data input again
Boy this brings back memories. These were called “Fox hole radios” invented back in the war.
My uncle introduced it to me back then, he was in the war.
You could get AM radio stations.
“ One common type was made from an oxidized razor blade (rusty or flamed) with a pencil lead pressed against the blade with a safety pin. The oxide layer on the blade and the point contact of the pencil lead form a semiconductor Schottky diode . . .”
My first electronic project was a 2 transistor AM radio that I built in Science class in high school around 1966. But I really hooked when I discovered digital electronics in the early '70s. Big thanks to Don Lancaster author of the TTL Cookbook.
