Got one 8-bit card here that also has an internal edge

socketed,
looks like UM8326, and a bunch of LSTTL glue logic.
Probably a floppy card, or QIC floppy-tape card.
Got one which is an 8-bit card only there's a
little sticker near the card
edge connector that says "pls plug into the 16
bits slot only" -- why
would
Interface card for a Spot Technologies (RIP) Fototak slide scanner--a very
cheap device.
The next one is labeled (in the foil) "ICS2110
Demo Board Rev. A" and sure
enough there seems to be a square socketed chip labeled
ICS2110 in there.
Most likely a sound card. The Turtle Beach Tropez used an ICS 2110:

The last one is also a 16-bit card. On the metal brack
is a 50-pin
connector (same thing you'd see on an Adaptec 1520, 1540, etc.) and on the
opposite
end is a 4-pin "drive power" (like in any PC)
connector for power to
apparently be supplied_to_ the card, a small button ("tac" switch), and
a 2x5 pin
shrouded connector.
Probably a SCSI adapter card, My guess is that the big power resistor is a
bit of ballast for the termination power. Altera is still very much in
business and sells interesting things such as FPGAs.
