Use heat gun or hair-dryer on them.

those are test fixture boards. one of a kind, built to spec by the manufacturer for the costumer for prototypes.
I don't think so. Those look like pulls from old IBM PS/2 desktop computers. I have those same cards here. Good haul!
If you do dump the boards in HCL, don't do so until you've cleaned them up first. Some of those chips have a aluminum cap plus I see a heat sink beside that OKI chip, should be another gem under there.

the boards themselves are not actual printed circuit boards. its just a generic type board that you can solder in components in any configuration and then run the connection to each component separately. they can be re-used if you unsolder the components. thats why the are used in test fixtures, its kind of one board fits all. just because they are in a piece of equipment that was mass produced makes no difference. it could be they were just using surplus stock or they didnt have a template for the completed circuit board.
Yes, you're right... they do look like prototypes. But I also recognize IBM's in-house signature style of board assembly which was unique in the industry.

Regardless, it's all good E-scrap, the OP did well.

That is a standard IBM type server board. I have recycled 1000's of those exact same boards. A good quality heat gun, a vise, and a screwdriver and you can pull the CPU's right off about as fast as you can heat the board.
