ID these boards?

I have a couple of boards here, not sure what the heck they are... They're both full-length ISA cards, a 50-pin (!) D-type connector on the metal bracket, 3 or 4 sets of DIP switches, and a LOT of jumpers. (70-80!) Both are marked "Frontier TEchnologies Corp. AdCom 2-M Controller", one is also marked "Version 3" (this one also has a holder for a coin cell on it) and the other one "Version 5". There's also a Z80-SIO and an 8253 on each board, and the Version 3 one has an 8255 as well. While I'm at it, I also have a keyboard here marked "Wyse Technology 1983" with a really odd 10-pin plug on the end of the cable. Nice individual keyswitches if anybody wants that for salvage, or can use the cable. This one' s a little different than a lot of that other stuff in that there's no LSI on the board. Complete except for the plastic covers not being there.
