I had to do get a separate computer for my embroidery machine. I have a MAC and my husband has an HP. My machine is a Viking Topaz and the program to use the MAC was in excess of $2,000.00! So I bought an HP lap top, it gets used for my Topaz, and my daughter borrows it from time to time for her work that is not MAC friendly.
A friend of mine has a grandson that works for a firm that repairs computers - maybe if you talk with an independent repair firm they can hook you up like Prism99's husband has done.
