Cromemco 8K Bytesaver EPROM board. Working. My dad and I each built one of these. I think this one was mine.
Here is the .PRN file from a simple program I loaded into a 2708 to test my ability to program an EPROM with Martin Eberhard’s post era ME2700 Orphan EPROM Programmer. On my Imsai front panel I examined the address C000 then pressed run. Yup the programmed output LEDs change state based on the programmed input paddle switches.
ME2700 EPROM programmer firmware and documentation located here.
Now it's off to find a simple monitor program to load in EPROM(s) and decide which I/O card to use for serial communications.
