On the board on the left of your picture. the top left chip reads:

See if that does anything.
I've come up with 18 cross references to various combinations of those IDs. All pointing to character, print, and output. Nothing specific for them though.
The black chips are all rom or low capacity memory. Nothing really special in these.
But the metal capped chips, I'm almost, certain are memory.
Probably track ram or bubble memory. Either way this is where some extra effort can pay off well. Seeing these boards are all pad layout you could easily do a reflow and harvest the chips.
As is those boards are telco.
Remove the ICs you'll probably get peripheral for the boards but as I said before this design of memory gets some nice payouts on ebay DOA.
And even if you don't want to ebay them they will all get at least IC rate.
I sent a handful of bubble memory to Chris once a while back just to see what they'd do with it. And he gave me telco for the memory. I haven't sent them since because I get a dollar a chip on ebay for them.
But you may want to try ebaying one boards worth and see if it's worth the ebay effort for you.
Email Chris a closeup of the memory as well and see what he'd take it as today when loose.
