Schematic for the IMSAI 80080 board?

[GaryBoone]

I'm debugging SMD soldering, so would like to check the schematic for the IMSAI 80080 board. Is there one available?

I don't think Mr The High Nibble has published that, as is his prerogative.

There really should be a schemactic. I spent a whole day tracing out how the SD interface is hooked up to the esp32, because I am one of the many who botched the hand soldering of a surface-mount part. After a day of tracing, I found out that I could insert a ready-made SD-I/F with a pin header into the through-holes below RN1. It really shouldn't be that hard. There is not a lot of intellectual property protected by not publishing the schematic. A few days wasted with a multimeter, and the job would be done.

I have received an email from Dave, saying that schematics will be made available on request.
