Homemade 8 bit Computer

Showing off my homemade 8bit computer. I built this using only basic 7400 series integrated circuits. It can t do much, but building a computer from such lowlevel components was a bucketlist item for me. Hope you enjoy seeing it as much as I enjoyed building it Some factoids: Total material cost: 400 Max clock rate: 0. 5 MHZ Total number of breadboards: 36 Number of jumper cables: I lost count, but Amazon was delivering a couple packs a week. Most difficult module to build: The program memory (the chips I used have a very complicated procedure for writing to them). Easiest module to build: The memory and the register file. Number of months I haven t been able to use my kitchen island: 3
