I'm planning to build these:
I'd just buy them. But I don't think he's going to be making more any time soon. So I plan to make them. The gerber files are on github. But there's no bill of materials. And he's not responding to me.
For the keyboard interface, I can identify the three chips from the photos. And the resisters are marked on the board. The crystal is 8, 10, or 12 mhz. The problem is the transistor. Also, a later revision of the board has a cap. I can't find a value for the cap or a part number for the transistor anywhere.
For the joystick interface, there's a cap transistor also.
Also I wish I had part numbers for the switches and that pot.
Does anyone have these boards and can read the transistor and caps and let me know what they are?
