Gigatron TTL microcomputer
This is one of the most fascinating projects because the Gigatron TTL microcomputer is a minimalist retro computer. It's special in its own way because it doesn't contain any complex logic chips, not even a microprocessor ! We chose to build a general purpose computer using simple TTL (transistor-transistor logic) integrated circuit logic, the main components used in computers in the 1970s.
These components are still available on the market today. To make it interesting, we do not include a 6502, or any other microprocessor in our design! Our CPU is made out of a handful of TTL chips instead of a microprocessor. With this you can look inside the CPU, follow how data travels through it, and learn how computers really work at their lowest level. The fun is that this TTL CPU is still very powerful. We even believe it is faster than the first IBM PC.
