An old project -- kind of an Arduino, 1994 style. #wirewrap board, #z80 CPU, SRAM, EEPROM, a 2661 UART+crystal I swiped from a dead Zenith Z100 board. I didn't have an EPROM programmer so I just breadboarded a circuit to let me use toggle switches to set addr/data and then push a button to apply the programming voltage. Checked the boot code I wrote VERY carefully. It sets up the 2661, reads a program from the serial input, then executes it. Mostly I used this as a serial->parallel converter.
