Does anyone know did IBM invent microcoded control stores then? This is pretty fascinating.
- fanf2 8y agoMicrocode was invented as part of the EDSAC 2 project at Cambridge University in about 1957. EDSAC 2 was also the first bit-sliced hardware design (which made it easier to replace parts that had failed).
- bogomipz 8y agoInteresting thanks. What is "bit-sliced hardware design"? I am not familiar with this term.
