This should be interesting.

There’s at least a 7% chance I’m going to be able to put this back together. 😬

Good lord. It’s like Zenith took a bunch of separate products and wired them together to meet Sun’s spec. The RCA jack on the neck board is where the video signal comes in from the 13W3.

This should be interesting.

This week's side quest is checking to see if this Sun-branded Sony monitor that I just bought on eBay still works. So I need a Sun workstation. I haven't turned on the SPARCstation Voyager for about five years, and anyway need to replace the NVRAM chip.

Here's the back

I noticed this. These (red) potted components are likely pulse transformers made by VAC (a German company that Sun used for high-tolerance magnetic components).

Here's the front. The graphics connector and floppy are disconnected in order to remove the bottom rear cover.

The anode lead on the fly back transformer is not in good shape 😭 The cracks and the chip in the wire are going to cause problems, assuming they didn’t already when the seller turned it on. I have some special conformal coating on the way. It comes in pints.

The conformal coating went on perfectly. I used a dropper bottle to apply at the top and gravity took care of the rest! Now just need to leave it a week to be sure it’s cured.

My life seems like a world of nested side quests. My new printer arrived last Saturday, and so now of course I’m building a stand that won’t collapse at any minute.

And wiring upgrade complete. That’s one project popped off the stack.
