Trying to help my Aunt out with her machine

Hello!

So I am currently visiting family, and my Aunt recently acquired a Brother Embroidery Systems BES-1240 BC. She has gotten a few runs going with her current setup, however the computer system being used is extremely dated. My question to you fine folks is, is it possible to get a new system put together that still allows the machine to function? The two current machines are almost as old as I am, running WIN95 and WIN2000 (I think). I would love to figure out if I can get her a new computer put together that operates faster than the current setup. Any help would be greatly appreciated, and I will try to answer questions as best as I can.

Thank you all!

Corey
