I like it!!!!!!
I can't wait. My son has a sumo robot kit waiting for summer vacation to build that would hook
up very nicely to the proto board and an Apple II.
That's great, Mike. I connected a 6522 to a pro to board a few years ago and use it for all kinds of projects. Having working interrupts and an EEPROM will make this the perfect hobby board for the Apple II. A couple of questions: Is only 2K available from the EEPROM or can it be bank switched? How is the EEPROM write enabled?
The four high address bits of the EEPROM could be tied to bank select logic, but I didn't include it. The last page is used for I/O select, so it should be maintained across all banks. I added an external write enable jumper for controlling write access to the EEPROM.
