Is there anywhere I can buy a motherboard with 2 ISA slots? I need to replace a computer at work, and the new computer must have 2 ISA slots. I could just buy a new computer from the company that supplied the original PC, but they are going to charge $5000, which is ridiculous. If at all possible, I'd like to build the new PC myslef and save about $4000. However, I've looked around, and I'm having trouble finding anywhere that sells a motherboard with 2 ISA slots. Thanks for any help.

actually, CPU socket type isn't all too important to me...the two ISA slots are all that really matter. As far as the other specs go, I'll pretty much take what I can get. I don't need high end sound or video or anything like that. As long as the processor speed is reasonable, it doesn't matter which socket type it is.

If your looking for a newer board with isa, forget it...i haven't seen a motherboard with isa slots since pentium3. If you must have isa, try ebay.
What card do you have, that requires a ISA slot? scsi card, modem? maybe better off buyin pci card or something.

There are several overstocks and surplus sales outfits I've come across on the web that have a lot of that old stuff. If I recall correctly, I (originally) found them through the ordinary price comparison sites, by searching for "P-II" (there was such a PC around here just two years ago now). I have used Google and "surplus PC parts sales" recently, and found some of the same places, still in business. If you go on eBay to motherboards and enter "ISA" in the search there, you'll find literally dozens to choose from.

(I assembled a Socket 7 PC with a 475 MHz cpu, two ISA slots, three PCI slots, and an AGP 2X slot recently, for a total cost of parts of about $150, I think.)

You may try a used computer store. If you don't need it for a long while, I have one but i'm using it. i'm trying to find a new board. It is a Slot-1 with pc100 memory and two ISA slots. i would also include Memory and The proscesser. PM if you know where a board is or if you are interested.

I'd missed that the first time around with this thread. That word is NEARLY as atrocious to use as the word "BEST", which is a silly joke. The fastest ANYTHING that was last made using an ISA slot was about 800-900 MHz (made for a Duron, in Socket A, by ECS, I think). That isn't a reasonable speed in my personal opinion ("reasonable" being so very wide open of a term), for anything more ambitious than a LAN's firewall or a print server.

There is at least one P4 board with four (!) ISA slots, intended for "industrial use" but there you go.

Other than that, you'll have to step back to the early socket-A days, or, if you prefer Intel, late P-III.

SA, here's an Asus P2B-F 440BX board w/ 2 ISA slots, for $20. It's a Slot1 board. If you need a PII-350 Slot1 cpu PM me. I could part w/ the one I have for a very reasonable price.

Another alternative is a system I have running as a second system here. It's a Soyo 440BX board (2 ISA slots) with a Celeron 1.3GHz and 512MB PC100 SDRAM. PM me if that tickles your fancy.

I think I saw a P4 board with one or two ISA slots posted here, if I can find it I'll link it.

These don't work unless the board's BIOS has support for PCI-ISA bridging. (Normally, a modern board would set the southbridge up to route all ISA traffic out the LPC bus toward the super-IO chip. With an actual ISA bridge present, the BIOS must do a handful of things quite differently.)

Plenty of boards out there with ISA slots...how much do you have to spend? Below each make/model, I included some retailers who seem to have the boards in stock.

As tempting as the Soltek board may be, I would not recommend it as Soltek isn't a company with a reputation in the server and industrial board market. There aren't even any BIOS updates posted for this board on Soltek's website (and may never be). The SuperMicro P4SCA would get my vote as the best featured for the price and its from a solid company. If this 'older' computer will be running Windows 9x, stick with one of the Intel 845 boards.

iBase Taiwan (or their OEM/ODM) manufactures several P4 ATX IPC boards with 2 ~ 3 ISA slots, based on chipsets ranging from i845 to i915G (with PCI-Express no less), but the least expensive model starts around $300. iBase boards are marketed under many different private labels and integrators, none of them offer much in the way of online support or BIOS updates:

MB800 (F/H) (PGA478 + 3 ISA)

MB820/F (PGA478 + 2 ISA)

MB865 (F/V) (LGA775 + 2 ISA)

MB880 (F/V) (LGA775 + PCI Express + 2 ISA)

The SuperMicro P4SCA would get my vote as the best featured for the price and its from a solid company. Its been on the market for nearly three years now and at least a few BIOS updates have been released, the latest dated OCT 25, 2005.

The SuperMicro board is FAR more likely to work well with a broader range of ISA controllers, due to SuperMicro's expertise in industrial and server boards.
