His design has an 8-bit data bus but a 4-bit ALU, and an impressive 2-stage pipeline and RISC instruction set which sets it apart from the computers most of us had when 74-series logic was a much ...

Hovey's 8-bit ALU (arithmetic logic unit) is constructed completely out of transistor-transistor logic (TTL), as are the registers. The microinstructions (the op code, the ISA) that actually ...

Complete with a 1024 byte memory, a capable ALU, four seven-segment LEDs and (in the second version of the computer) a 2×16 LCD disply, this 8-bit computer has it all. Not only is this a capable ...
