This is interesting. Are the DOS apps? Do they require some piece of hardware to run such as a dongle?
I have a mixture, early counting devices, vibration, shock and accelerometer, and temperature measuremet were designed and built to work with the the ancient Windows 3.1 but since that really was not a true o/s in reality the command structure is DOS. We use them primarily with Xp using Xp as an on/off switch. The majority of all pressure, strain gage, motion meaurement are newer and do not use a a dongle ... just a strict measurement of counts/voltage.
What HO is saying, is that in the changeover back to Xp from Vista something was corrupted. That I do not understand completely, becaue at first Xp was loadeed and Vista disabled, but when that did not work, all units were totally fornmatted, and Xp reintalled. That did clear uip a lot of problems with older printers and such, but none of my proprietary mearuement systems.
PC’s drive me nuts ... I’m a physicist, that in Pre 1985 years dealt strictly with mainframes but of course that was in a single fixed lab situation .. so much simpler. Ok .. I’m a dinosaur.
