It's done. After hours of reading my own schematic, counting pins and stripping wires. The Zwölf is on the breadboard. Almost. First it's time for a smoke test to check the voltages and the clock. Only after that I'm going to install the processor.

Right now it's just the bare minimum. The processor (the empty socket for now), 32k EEPROM, 32k RAM and two logic ICs to latch the uper half of the address lines and decode the chip select for the memories.

Here it is!

Am I glad that the CDP1802 is not a 64 bit processor. Smile | :)
Ok, I take bets. It's still a little light on the I/O side. It can only blink on a single LED or give smoke signs.
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
