Looking good with the wire-wrap and the bypass caps! Love the serial port.

it's actually running programs! :D Love the bit* about the TTL 6551 ended up being the superior version for you.

I really like the layout of your board. I'm doing something similar. One thing I did was take a 16 (2x8) pin wire wrap socket and solder some 3K3 resistors in it. So that I have 8 pull-ups that can be easily wire wrapped. I struggled getting my ZIF socket in any of the dual-wipe sockets. I also couldn't get the ZIF pins in the WW socket. So I'm just going to have to solder it. Another idea I'm going to try is to solder decoupling caps onto two WW pins. Then, use small jumpers (like you'd see on a hard drive config) on connecting the WW pins to my component VCC pins. The jumpers will push all the way through and it's super tight.

hooking up my WDC65C51 now, thanks for the realterm pointer

Hi can you tell me what editor @ IDE you used for the coding ? Eclipse ?

[KomradeMikhail]

Loving the build so far... But can we get more of the giant crayon lamp in future vids ?

Maybe I missed it...how are you ensuring that RAM isn't written to when Φ2 is low?
