Are you referring to the software for the uPSD devices, originally by Waferscale Integration, Inc ?

Although WSI was acquired by ST in 2000, the parts are long discontinued

Sorry, can't help you there.

Your best bet is probably to find a copy of Windows-NT or whatever was supported by that ancient software.

You should probably also be thinking urgently about replacing that ancient part!

This guy found a commercial programmer with support, but even that is over 15 years ago now.

Maybe you can find something on ebay...?
