If you don't mind me asking, how did you source the custom keycaps?

There are several companies that create them, in this case I used Maxkeyboard.com. All you need to do is create a template file with the graphics you want printed (a svg file) and select the layout and colors.

Ah! You have it working! Did you happen to make a note of the error(s) in the schematics I published? Ive been meaning to get back to troubleshooting, but free time seems to be a very fleeting resource for me lately.

Ugh!! I do not recall exactly what I needed to change, but I do not think it was too significant. I will try to spend some time this weekend and review what I have and see if I can figure it out.

I do know that MOST of my changes were around adding the extra 32K of RAM and fitting a grom emulator. I have a vague recollection that there was something small -- I will try to remember that and get you that info.
