Bill:
Happy to share and happy to bring back some fond memories for you.
The wire wrapping was very tedious and it wasn't just the one INS8073 board. There were three others that were wire-wrapped as well. I did't realize that RS had charged US$25 for a spool of #30 AWG Kynar wire. Yikes! Before they closed stores a few years ago, I grabbed about 4 spools for about US$3 each. I don't do much wire-wrapping these days but I do use the #30 AWG Kynar wire for rework and repairs. :)
I have an 1802 in my parts bins but never put one together nor have I done any programming on one. I've thought about it on and off over the past year, so I may at some time do so. :)
I have Lee's Z80 + SIO card set. No front panel. It seems to work well with CP/M. Josh did a phenomenal job on the firmware and software.
Peace and blessings
