Hi,
I'm a long time lurker, first time poster. I recently obtained a mobo that
was sitting around a local computer store, and am having a little trouble
with it. It's a 386SX motherboard, with onboard parallel, serial, and PS/2
connectors. I was planning on building a little box based on this, but the
problem is the lack of ISA or PCI (obviously) slots. Instead, what i have is
a bigass connector. It's about 2 1/2 times bigger than a PCI slot. I'm
thinking this may be an extension to plug in another card with slots, but I
have no idea. Can anyone help me? If you need more info let me know, i can
supply it. The brands Faraday and WDC are displayed prominently on a lot of
the ICs.

Larry,
That's Western digital corp. made those boards, Find any old LPX
machine with 120pin slot tree card. It's pin compatiable and
mounting holes are compatible.
I can't help you with jumpers, someone might have it somewhere.
There should be a number printed somewhere on the PCB itself.
I had one but it was 286 version.

Sounds like it wants a riser with the isa slots on it. Those tended to be
proprietary, you may be out of luck. I know Digital Equipment, Packard Bell,
Radio Shack, and myriad others produced boards like this.

These slots for expansion were EISA in many cases, e.g. HP, Packard Bell, etc.

EISA?? That doesn't sound right to me. Some of those computers even
have PCI slots, but how could PCI run through an EISA slot? Would that
be a huge restriction? Most of the ones I have seen are either ISA,
with only ISA slots for the cards, or some other proprietary connector,
and/or cables.

Don't pay any attention to the riser connector whatsoever. Computer
manufcaturers will just use whatever comes in handy, is cheap and plentiful.
So of course they will use common connectors which they will have in store and
sort out the actual expansion slots on the daughterboard.
I just think it's sad that there is no standard for slimline motherboards and
their risers. I wouldn't mind being able to put together flat desktops or
really thin towers out of standard components, but as long as there is no
standard form factor, everything home-made will have to be bloated tower of
some kind.

Your throughts is right, aren't EISA.
That "eisa" like slot is Intel's only design on many of their LPX
boards. Not EISA standard. It's just merely a connector choices
they took for PCI and ISA risers. I'm sure your "eisa" slot riser
type LPX machines some of yours is intel LPX boards. IBM used both
by buying some boards from Intel's and making their boards as well as
standard 120pin LPX types. Sometimes lt looks like long PCI style
with pieces of straight through crackers (usually 3 of them)
between that and daughterboard slot riser. Connectors but all the
same it's just design choices.
BTW, your WDC 386sx board is standard LPX w/ 120 pin riser slot.
If you have a old IBM desktop box with 120 pin riser and standard AT
power connector pair, try these.
Don't pay any attention to the riser connector
whatsoever. Computer
manufcaturers will just use whatever comes in handy, is cheap and plentiful.

Correct, Some of them are standards some aren't.
PCI spec doesn't take much pins even it has 32 traces plus other
wirings, so other pins on that "eisa" riser connector is plenty. In
fact, upper contacts is ISA in pinout, while bottom contacts are
for PCI but pinouts is not.

I made the observation that the connector looked like EISA. Just because the
edge connector is the same doesn't mean that IS EISA, though it may just be
using the same connector for signal transport.

It's about 2 1/2 times bigger than a PCI slot, as i originally mentioned. It
looks a lot like an ISA port (ISA style connectors and black casing), but is
a lot bigger. There's only one connector on the mobo, which does support the
riser card theory. Luckily, the system has onboard video, serial and
parallel ports, etc. so it won't be so bad.

Can you be more specific?
There doesn't seem to be full standardization of bigass.
It COULD be EISA, or it could be something uniquely proprietary.

Also, the fact that it has all that stuff onboard gives weight to the
theory that it went into a slimline machine. I had a machine like that
(486SX) once.

Sounds like a Packard Bell box. They used an EISA bridge to an expansion bus at
right angles to the mobo. Of course just because it looks that way doesn't mean
it really is.

Seriously, though, it sounds like you have a motherboard made for some kind
of slimline case. Into the bigass connector probably plugs a riser card
with the real ISA slots.
