* dBase/Clipper/CLARION/Paradox/other DOS RAD environments on period hardware to run business processes?
* CNC mills/spectrometers/microscopes/other industrial instruments controlled by ISA cards (either bespoke or standards like GPIB)?
* Anything with a parallel port dongle?
If so, I'd be very interested in hearing your experience here, or feel free to send me an email at the address in my profile. I'm not trying to sell anything, just doing some research for an idea around keeping these going on modern hardware.
