Please excuse the clutter in the pictures. I'm out of storage room and can't really move stuff around so easily. I have mainframes and I'm not sure if there are buyers for them as a whole piece or if it's worth breaking them down for all the boards inside. Any ideas?

That’s so older pc/micro computer stuff. Looks pre-pentium era. Whole and working the normal ebay range is somewhere around $25-$50 but shipping eats most of it up.
Apart you have some valuable processors, dip socket ICs large socket or telco grade motherboards. Plus whatever else is added into them.

Found more info on these if it helps...

IBM AS/400 9404

https://www.ibm.com/ibm/history/exhibit ... _4010.html

https://www.ebay.com/sch/i.html?_from=R ... 4&_sacat=0

The Wang unit doesn't have a part number I can see. It's like 2 feet by 2 1/2 feet and must weigh 100 lbs. It took 2 of us to haul it back here. Same thing with the AS/400.

The small IBM unit is a tape drive:

For the smaller Wang unit is also a tape drive.

Yep. Looks right. Lol
The AS series were RISC microcomputers. Either a 3rg gen IBM RISC chip or a 1st gen power processor. Either way a socketed ceramic is a near guarantee.

The W micros were mostly DIP CPUs in that era. So you score big with one or more 8086 class chips or strike out with replacement plastic silver leg ICs depending on how much repair was done to it.

The tape units produce a peripheral or CD/DVD class board plus extras.
None of those are really hard to take apart.
