Some pics of the project

Mark 1 in all its glory

Twin LCD displays. 2-line for RTC and Uptime. 4 Line for monitor.

RTC Chip and 2 debounced push buttons on the top breadboard. RTC is fed with 32.768kHz from a function generator awaiting for a new xtal.

4-input AND gate for VIA IRQ connection to CPU on the other breadboard.

I/O board with 2 65C22 VIAs. Beeper piezo sounder in the Altoids tin.

Planned to be built using Wirewrap methods but seems to have been forgotten about
