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. 
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.

Very nice work!
I bet on 'no-smoke' with such a well organized breadboard...

You would have won that bet. Now It's time to get the oscar and check the clock and the reset logic.

Looking good, smoke?

Nothing gets hot, power LED lights up, voltages on all ICs are correct and at the right pins...

That could still happen. Send over about 15 kg weapon grade plutonium for the nuclear batteries and I will build a replica of the Galileo probe. But then I will need five more processors and I actually don't want to crash it into Jupiter when it runs low on fuel and the only thing that still works are these little processors.

Mine started to stick quite a while ago but I took it apart and cleaned it and it's working much better. I know this one will eventually fail so am keeping a lookout for a good mechanical keyboard on eby and I ran across this baby...

$2000 for a vintage IBM keyboard? I'd say that's totally insane.

Quote: looking around for a keyboard replacement
voice-to-text is getting better, as long as you don't have an accent Alexa's pretty good.
if you prefer touchy feeley (don't want people hearing you search for pron) you could cheek out the sort of gizmo Steven Hawking used.
there's more but that should get the ball rolling.
after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

Hmm Hawking not using his anymore...

It's nice though because on the easy payment plan you can pay a low $84 per month for 24 months.

Even if you got that, you'd probably need an IBM 5250 terminal to connect it to. See Here. The photo shows what looks like the connector in the background, and that's not even an AT style connector.

I'm glad you pointed that out before I ordered.

The first keyboards I used had 25 pin RS-232 connectors, and plugged into the screen. The screen was a character oriented one, 25 by 80 char, monchrome green (nice for Jenkins!), with is own 25 pin RS-232 to the computer. No, it was not a PC.

So $2000 for an IBM keyboard.
That's about a 50% discount from what IBM used to charge for them in the 70's isn't it?
