Okay, retrocomputing nerds: anyone recognize this weird-ass midplane I've had kicking around? Probably old IBM equipment.
Boost if you think it will help.
@phooky What does the other side look like?
@ardgedee both sides are pictured! (The back looks a lot like the front.)
@phooky @ardgedee any solutions? Maybe something to build CPUs using technology similar to https://en.wikipedia.org/wiki/IBM_Solid_Logic_Technology ?
@saper @ardgedee It's very similar to this system/370 backplane-- I think you've nailed it!

@phooky @ardgedee reminds me of http://helmer.sfe.se/
I think I am going to fire up my VM/370 on Hercules out of nostalgia!
@phooky @ardgedee your backplane looks way smaller, but there is something similar, yes!
I think I got to understand the origin of the word #mainframe itself. They were delivered as empty cabinets (frames) that had to be filled with those backplanes and cards... As StackExchange suggests it goes back to big cabling frames in the telephone exchanges.
