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.

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.
