This was my NeXT Mail avatar at that time, back in 1992. (64x64 pixels with 4 bits of each color channel per pixel (444 RGB) felt like a pretty high quality image in that era!)
The self-photo was taken in NeXT's sales office at Carillon Point in Kirkland, where Omni's founders were working as consultants (across the lake from Seattle), by hooking up a camcorder's video output to the video input on a NeXTdimension board.

Woohoo! Life out of one of my Sun3/60's!
You could say my transistor tester fixed it - I took the 3 through-hole transistors off the small daughter card, tested them, and soldered them back - and it's alive!
And it's repeatedly arrive, even the next day.
My reading of the service manual is that flashing LED means it's trying to boot; so time for a serial lead!

The diag LEDs on the back of a Sun3 workstation; they start running through a pattern and then sit there blinking one. They're a row of 8 small red LEDs.

Looking at Sun3 psu parts again, it seems to me that they were designed in negative - this little daughtercard makes it pretty obvious - they've not laid down tracks - they've down the gaps and ended up with sets of lands. The whole board is only a few cm across, so I don't think anything here is taking significant power.

The back of a small daighterboard PCB against a nice purple background. The PCB is the standard green tracks on a darker board; it's through hole and there's no components on the back, and there's a set of pins at the bottom. The interesting bit is there's no thin tracks, there's thin breaks between areas.
