I put together a Z80 microcomputer the other day. Real simple:
processor, clock oscillator, NVRAM holding program and data, pair of
74LS138s for memory and I/O decoding, and two 74LS273 latches for
output. And a forest of jumper wires. Right now I have it scrolling
a message across four matrixed digits of seven-segment display. Seven
segments make really ugly Latin characters though. :-(
