TEK 485

Post by MED6753 »

This should make tggzzz's day.

I have two 485's plus a parts mule. So why not have a third? Facebook marketplace find. It's dirty but complete. Not even a broken knob. And of course it's going to get my usual due diligence. But not today. It's the 4th of July and we celebrate our independence from you stinkin Brits. :P :lol: Later today we will be going to a cookout of hot dogs and burgers and then tonight celebrate with our own fireworks. (Illegal in New York State without the proper license but a half hour away at the Pennsylvania state line is a huge fireworks store)

All my project finds lately have been Facebook Marketplace finds. Prices are reasonable or even dirt cheap....unlike Ebay.

Am I imagining things or does it appear that this 485 might have a blue phosphor CRT?

Blue is good. :)

C911 and other beads on that rail aren't (or soon won't be) good.

That and at least 2 dozen other bloody tants.

That half dozen are difficult to find on the boards and even scattered across several schematics, and are 15V on a 13V rail.

The main PSU is easy by comparison!
