This is just a quick tour of my homemade Kenbak-1 computer. The Kenbak-1 was designed in 1971 by John Blankenbaker and is considered to be the first commercially available personal computer (that wasn't a kit.) It contains a TTL based serial processor (no microprocessor) that processes instructions one bit at a time. It's memory consists of two 128 byte shift registers, giving it a total of 256 bytes of memory. No rom, permanent storage or even digital I/O was available.
My machine is still a work in progress but is now fully functional... I'll be making a new case for it next.
