I built one that sounds very similar. It was started by another student and i then added
mult and div. Dont know if the initial build was from a design doc. I had the whole thing
drawn out on large paper sheet but alas long gone xx

This thread reminds me of a computer we built at
school from discrete
transistors. Each transistor was a NOR gate with three resistors on
the base and a collector resistor. All soldered onto squares of tag
board. We put a bunch of them together to build a shift register with
small laps as output. That would be about 1969 or 1970. Does anyone
remember any more? It must have been a published design somewhere.
Sounds like plain old RTL--which was certainly available in 1969.
