Most of the credit goes to the hardware guys that were able to finally isolate the problem.
We found the bug, but the months of delay (and a few other problems like losing a big contract[1]) killed the startup a few months later. While I'm annoyed the SCSI3-over-{HIPPI,ATM,FDDI} switch I got to work on was never finished, the next job doing embedded Z80 stuff was a lot more fun... and a LOT easier to debug.
Incidentally, I found a picture[2] of the NIC. Note that HIPPI is simplex - you needed two cards and two 50-pin cables. This made the drivers extra "fun".

- jacquesm 11y agoThat's a beautiful board. I remember the FAMP made by Herzberger & Co at NIKHEF-H, I used to hang around their hardware labs when those were built. Similar hairy debug sessions in progress. Those worked well in the end iirc and ended up at CERN.
