I have put online some pictures and schematics of a rather pathetic
homebuilt TTL machine I constructed around 1985
Specs 12 bit wide, 8K ram, 256 word hardware stack.
CPU 3 x 74181
Hardcoded instruction set.
No blinkenlights, but, almost as good, 4 nixies as display.
I really like the nixie display. A cool machine.
