Justin DavisStill building - not quite to blinking lights yet. Lots of soldering. I ran out of 20-pin sockets, so I had to put some on order. I also didn't realize I had no 750 Ohm resistors. I've also been seeing if there's a drop-in ZIF socket for the ROM, but I haven't found one yet. I probably should have thought of that during layout. It may help if I do lots of ROM updates. More likely I will just build the cartridge with reprogrammable memory.
While I'm waiting I can start loading chips and testing starting with the ALU and then the X/Y registers. I'll wait for the Cherry MX keys until I have everything else checked out since they are fairly expensive (at 63 of them are).

I have a lot of 750 ohm resistors if you want me to send some. Just message me your address and they will be on their way :-)

I already have some on the way, but thanks for the offer!

Or just use 680 ohm. Its all analog in that area, your eyes aren't going to spot the difference.

try looking for some Low Insertion Force(LIF) sockets instead of Zero Insertion Force(ZIF). i've used them on a number of projects recently and they are much more cost effective that ZIF. https://hackaday.io/project/158510/logs?sort=newest&page=3
