Eprom Upgrade?

Can I still buy or burn a new eprom that will allow me to run my late 90s vintage North American market MicroMill under Windows VR Mill? I have original disks and security dongle for the machine and it currently works fine under DOS but that is cumbersome and even VR Milling V2 would be a welcome update. I have an eprom burner available if I had a hex file to burn!
I see lots of info but no clear cut definitive path to success. I appreciate your comments.

I used to have an eprom reader/burner and a UV box to erase. Wish I hadn't cleared out 'that old stuff' if I had I could read an eprom I have here. I'll ask some friends who might have a reader.

Yes I bought a cheap burner on eBay for about $60 and it has worked great the few times I have used it to copy firmware or create new eproms from hex files that I found online to update machines.

I know Denford sells replacement EEProm chips, and will gladly sell you a seat of Milling V2, but I don't know what it would cost.

If you have access to something that'll read the EPROM then it could be a good precaution to do so and save it as a back-up as they don't last forever. IIRC when I've looked at some of the data sheets for the EPROMs I was using 10 years was a typical minimum life quoted, they normally go on far longer. I know someone who a couple of years ago had a Bentrup temperature controller that flagged up a ROM fault and fortunately Bentrup still supported it and a trip to Germany and back for the controller saw the EPROM reprogrammed.
