The #Datapoint2200 keyboard PCBs have arrived and they look fantastic. Somehow larger than I expected, and very imposing.

Shout out to @StepanResl and #DataBrothers for organizing this conference, it's gonna be a real banger!

Todays test program: load values into the A and B registers, add (or subtract) them and loop.

I've got the jump working but the ALU ops are not so pretty. It's inverting each bit of A if the bit in B is set. The circuit for the ALU is all standard gates, and I'd be surprised if there's any bugs in there given the rest of the simulator is working so well.

So it's probably a schematic issue, and one which will take a bit of debugging.

That’s the surface mount soldering finished on the #d2200 memory card. When I say finished, I’ve verified that every LEDs are the same way around. I’ve not checked they’re the correct way around. I think I’ll do some testing before moving onto the through holes. #datapoint #TTLComputer

I have a crazy project idea to recreate a #Datapoint 2200 computer. Or, at least the electronic parts. This is the first board.

It’s the decoder I board. The top half is the oscillator and derives timing signals from it to drive the processor. The bottom half decodes output port addresses. In between is the speaker driver and a couple of gates for the tape boards.

Does anyone know what this chip might be? Google is turning up a blank.

It's on the shift memory board of a #Datapoint 2200. Labelled '720', it's clearly a comparator of some sort. It's massaging the output from the memory chips to TTL levels.

Tables at the bottom show spare units (it's a dual chip) and power supply pins. This one takes ground, +5V and +12V.
