New computers no longer come with ISA slots, your only option is to purchase new PCI I/O boards. T

It looks like there are some hardware out there that can bridge an ISA card to PCI slots, but they are extremely rare.  I found one at

D'oh, hit the wrong button....

Unfortunately, you have to write the driver software yourself.

I think your best bets are just to buy the new cards (eeek $$$), or use old computers and then RDesktop/VNC into them with the new computers.

your first mistake was buying the computers first.  you can find modern motherboards with isa slots on them (such as this [http://www.ibase-i.com.tw/MB800pic.htm] pentium 4 based board)...

I'd have to say, look around a bit and find a motherboard that has the isa slot on it and everything else you need in these computers.  Then bite your tongue, replace the motherboard in the computers, and use that.

This will void your warranty if you bought the PCs from Compaq or anyone like that.  But it is certainly cheaper than the PCI versions of the card you need.

Here are a couple I found with a quick search. The first one connects to a USB port and gives you 1, 3, or 5 ISA slots. They also have enclosures and power supplies for them. It looks like you could get setup for about $150-$200 per computer depending on how many slots you needed and how many you ordered. The second one has PCI to ISA converters, but I couldn't find any pricing. It looks like they may only sell in bulk. You could contact the company and ask for pricing or locations of resellers.

What is the interface to the instruments?  It's possible that someone here might know of a cheaper PCI solution than what you've found.

I don't suppose you could supply the make and model No's of the ISA cards that your equipment connects to, and maybe indicate the type of port connector they use to interface with.

A photo from an old online resource would be helpful.

I came up with the same company as brakk0:

I think, though, that this comment does make some sense:

some motherboards has ISA like my Abit KT7A-Raid has only 1 ISA but most don't because they slow PC down

Sorry, dominhus, I gave brakk0 the sole credit for the link above.  I notice now that you mentioned the same page as I found, while brakk0 quoted the home page.
