With an adapter you could even do larger EPROMS 32K at a time. The first thing I did with my first AIM was to homebrew some battery-backed RAM (no Dallas NVRAMs in those days) and an EPROM programmer: an 8212, a ZIF socket and a switch to turn Vpp on/off is all I used, and it plugs nicely onto the expansion connector. I still use the AIM for reading and/or editing ROM images, although better programmers have taken over that function. Later Rockwell also published schematic and software for an EPROM burner add-on, but it had a few more parts than my minimalist version. m
