Version 2 of the board allows you to switch between banks on 28c256 eeprom using jumpers or switches

Plan is to make a usb ice to enable dev of physical rom on physical machine with a rear panel to switch between the banks

Oh wow! That does look nice, and very useful too, I bet. Did you make instructions for how to manipulate those jumpers?

(Not very visible under there is a row of pin headers with A12 removed)

I did wire it to the CH3/4 switch afterward so I wouldn't have to keep taking the cover off and moving the grabber. I think this will tide me over until your board is done.
