upgrate, good luck with that
We have some machines that have XP boxes to run them. The machine and software on the PC to run the machines use the game port to tell the program when a sensor is activated. After XP, there is no game port support. So, Microbrain wants us to dump XP, but for no real reason they gave us no upgrade path. How hard would it be to code in the driver for game port. Another legacy Microbrain fail.
