PC/104 or ISA motherboards.

Hi group,

I've got an embedded application that I've developed hardware and
software for on an old Pentium 120 as a prototype platform. I designed
ISA bus cards, and wrote some multithreaded software in linux, since
it was the fastest way of doing what I wanted.

The time has come now to make the whole thing more standalone and
develop it further using components that are still available. ISA bus
motherboards dont seem to exist new, and PC/104 seems very expensive
for what it is.

I've looked a bit at the mini-itx motherboards and so on, but none
seem to have ISA bus.

The basic requirements are:

High 486 or low end pentium class. (Basically so it can run a minimum
config Linux with enough guts left over to do the number crunching I
need. The P120 I'm running now is about right)

ISA bus is better (since the PCBS I designed are ISA edge connectors,
but I could redesign for PC/104 if I have to)

preferably ethernet on board, but of course I can use a card for that.
10Mbps is fine.

Still available new. We've gotten beyond being able to justify
scrounging old stuff.

Small(ish) form factor is better, but not critical.

anyone got any suggestions? I'm having a lot of trouble finding stuff
like this available in Australia.

I would have expected that a couple of hundred dollars should about
cover it, since it's be very old established technology.

thanks,
Cory

If you only want one or two PC104 mobo's, i may be able to help. I am
fairly sure that I have a couple of 486ish boards. Whatever they are,
they are still commercially available through advantech i think.

If you want to stay with ISA you are best to be looking at
Pentium boards or older some PII boards do have one or two
ISA slots but after that it is all PCI.

If you want just one or two machines to do this work with
you will find plenty in the second hand computer shops
and e-bay etc. If you are looking to market this, what
ever it is, then you will have to seriously consider re tooling
to PCI or PCI express.

I have a large box of PC 104 parts, work was cleaning up last year so
out these went.

I'll have to check what is the CPU on them, but I've at least one of
every type (IO controllers, HDD controlers, Video) and others that
I've no idea what they are for/from.

I have nearly two complete sets / pcs but require a second memory card
for the second one.

I'll check tomorrow what the cpu is if you are interested.
I know one set works as I was running dos off of it for a while,

thanks for the pointer. Most of the other replies missed the point
that it needs to be currently available. I'll check out advantech.

If i was just after secondhand stuff, I'd be looking in the dumpster
here at work.

Sure, you can still buy isa motherboards, even pentium 4 isa boards:

http://www.ibase-i.com.tw/mb820pic.htm

There mainly for the industrial world and there not cheap, but you can
still get them. Do a google search on pentium 4 & isa.

There is a P4 SuperMicro motherboard with GIGA-Bit LAN, Serial-ATA,
USB2 onboard AND ISA slots
The model is P4SCA ( search www.Supermicro.com for full stats ) this
is a full size MB so I don't know if would suit.
