Unfortuantly I am not to familier with this type of computor or where to find a replacment part. The computor itself is and old IBM that runs a Particle Analyzer from Malvern on DOS. My problem is in the IDE board (i hope) and with that I am having a hard time finding is a replacement that will be able to handle the tiny hard drive and old formating and the old mother-board. The IDE board itself was made by Western Digital and is copywrited 1988. It has a strip that is made to insert into the motherboard that has 31 x 18 "pins". (excuse my ignorance on these matters). It also has J1 and J2 for the hard drive and floppy drive? . Any suggestions?
Thanks,

Can you get a part number off the board?

Do you have a backup of the system when it was working?

It would help if you gave us more information. How does the particle analyzer connect to this computer. Or do you simply enter data into this program?

You can install DOS on a newer computer with no problem.

Can you give us information on the hard drive itself. You say it is tiny but that is a relative term. You mention IDE... so at least we are not working with an old 5.25" mfm or rll setup... So the format should be standard...

I am assuming at this point that this is an ISA drive controller and not a PCI...

What is the nature of the problem you are having with this system...

What error message are you getting etc.

I am kinda busy this week and I will try to check back soon but the answers to these questions will help others to further define your problem and come up with a fix...
