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. And across the top of the card is a big 2.4 ohm 10W (!)
power resistor, not the sort of thing I'm used to seeing on "PC"
hardware.
This one's all surface mount, and the one square chip in there is marked
"Altera", not a name I'm at all familiar with. No other markings on the
board except a sticker hiding under that big resistor with a barcode and a
rather long number on it.
This one came out of IBM systems (sorry, I dont recall the actual
models involved here). These systems were designed to be relatively
low-footprint, with the computer proper (minitower) tucked away
somewhere more convenient. These cards attached a remote floppy/cd
unit, as well as the kb and mouse (ps2).
Pentium/Socket7, replacable VRM, upgradable L2 cache (the unit I
have has ".2MB NS 32K x 64 3.3v 66MHz), odd construction. Used an AT
psu, ps2 kb/mouse, riser card for all expansion slots.
I had a customer with one of these systems, and they were ok for
their time. When they upgraded their system, I was given the old one.
Very handy design if you used the drives alot, but otherwise, it was
just annoying.
Best wishes.
