logic rack?

I have no idea what this is, but it sounds like it's
made of discrete-transistor logic, and LOTS of it
Would be a cool find just for all those boards,
maybe something one could build something really
old-school out of (like the guy in Pittsburgh who
built a 4-bit discrete-transitor CPU in 1968 out of
a lot of scrapped logic boards). It doesn't sound
like you snagged it, though. :(
