The Multicomper is a motherboard for the EP2C5T144C8N Cyclone II FPGA dev board, modelled on the "Multicomp" functional computer design spec by Grant Searle.
Grant has written up the circuit design notes together with the instructions to turn it into one of a number of computer emulations, including the original UK101, but there was no accompanying PCB design. A few others have designed "Multicomp" baords, and here's mine!
