Omax Waterjet Old Dos Software Operation. How Can I Convert It To Work With Windows?

Hello, We ave an old Omax waterjet that operates only on the old DOS system. I trying to find a way to convert the system to work with windows some how without sticking more money in it than what it's worth. I know guys have done it with like dongles and adapters, adruino kits what have you. Guys. If any of you can help me out on this one I would be truly grateful. Thanks in advance.

Do you have a n omax account, you can login on the support site and download the software, this machine will probably be running the 5 axis controller so the pc would need to be 32bit
Hope the helps
