I just picked up an Apple IIe and it has some strange boards
Board1
an eprom chip is covered with a label "SSB-1" there is a 10 pin ribbon cable
connector
that goes to a 9 pin female connector on the back plate. the biggest chip on the board is
a
SYU6551a - serial board of some kind?
Board 2
Says Digicard D-Net and has a wire that goes to a board in slot 1. biggest chip is an
am8530h-
6pc
Board 3
also says Digicard, The largest chip has a label that says "Digicard Video Network
V1.5"

The 6551 is a fairly common asychronous serial chip (with an internal
buad rate generator IIRC). This board is probably a clone of the Apple
Super Serial card or something like that.
Board 2

THe 8530 is a complex sync/async serial chip IIRC. It's the one used in
the Macintosh, etc. This could be some kind of network card (based on the
name), although it may well not use any well-known protocol.
Board 3
also says Digicard, The largest chip has a label that says "Digicard Video Network
V1.5"
No idea on this one.

Possibly
"Speech Synth. Board"? Is there an audio amp chip on it such as a
LM386?
Most likely Tony is right, it is a Serial S?? Board.
