Quoted from barakandl:
Since there is sixteen 2716 images one could build a 27256 EPROM board with a 4 position dip and pullup resistors to bank switch between each test rom.
I'd be interested in something like this. I want to try this out to play with it but having to locate and program 16 ROMs has kept me from doing so. I'm sure I have 16 laying around, but a lot of them have other test programs on them or are for specific games that I use to test. I really don't want to erase them for this and then later have to do it all over again to use them for the same purpose they're being used for now.
