Computers and all that stuff...

The UK101 was the first REAL computer I owned and built myself. early 1980's. 4 or 8 KB of memory, based on the 6502 CPU. All on one board. Saving and loading from tape was a problem, as the simple 555 timer based serial I/F, drifted with temperture... over time.

The Interak I have had for 30+ years. Based on the Zilog Z80 with 64KB memory, programmable graphics. recent updates have included using a 128MB CF card to act as 14 x 8MB drives. Built like a tank in a 19" rack and case, there's room for 12 cards to carry whatever kind of circuit or device that takes your fancy.
