This one seems to work ok though I've only used it a few times so far. I noticed it's got a space for a switch. Guess I'll try that and see what happens. After I back up the EPROMs of course.
Before the switch does anything useful, you'll need copies of the 13 sector P5 and P6 ROMs.
This Taiwanese el-cheapo design works fine with EPROMs faster than 250ns. Don't use your oldest 2758 only because 1kB is enough.
