I have an ancient piece of software that will only run on DOS/Windows 3.X It is used to program the Allen-Bradley PLCs, and read the outputs of a machine used to pressure test pipe fittings (Machine is from the early 90's). I believe the problem with more current OS's is the fact the program needs direct control of two serial ports. I have tried it with Win98, but it is unstable and tends to lock up ther computer.
I downloaded and installed Microsoft’s Virtual Machine from here
, but cannot get DOS to install on it, I recognize that the disks might be marginal, though I was able to get them to install on an old 386 Box (This adventure has been a real trip back through time...) Other than creating a box that is a dedicated DOS/WIN 3.X machine, does anyone have any suggestions on how to get this set up to run in a Virtual Machine that will allow control over the serial port?
(Remember when the first thing that came to mind when you saw DOS was "Disk Operating System"?)
