Sometimes a problem is a good thing, and you wish you had more such troubles. I have a couple of boards, pictured here, that I find it impossible to decide on a category: what do you think... 11 gold legged chips, gold fingers that do not appear to have any underlying copper, or any other color metal, and the fingers are so thick that when peeled off, are as thick as aluminum foil. Since I am new at posting on this forum, I got the boards out of sequence. First two are lots of color showing. Probably keep this one to hang on the wall.

The first two are typical middle-high end server boards and will go as telco.
The final board. Oh my.
Any of those socketed chips should be removed. The ones with gold legs and the gold window cap will all be 486 class. You may or may not be bumped to 8086 rate on them; there’s some value loss from the glass.
Nice set!

Thanks. I have a couple dozen of boards from this machine, I think it was Stromberg-Carlson from about 1980. I think there were about 35 of the gold top/leg chips total. About half the boards have six or so metal enclosed transformers, at about a pound each transformer, but all have the gold fingers.

From 77/78-83/85 these were quite common.
Some IT guy convinced a BOD that it would be less expensive to get exactly what they want and only that, from a sub-contractor.
All those ICs are EPROMs. They buy a whole bunch of individually useless boards and in house the code for the ICs.
Code guys made a fortune on these because nothing ever worked right the first time and with custom assembler commands the tech get to fix the problems. Good early examples of software vending lock-in!
