I have an old Dell PC that runs an older commercial vinyl cutter. The cutter is a high quality Graphtec and in great shape, but PC is old. The cutter runs off a parallel port and the cutter software is no longer supported. It has Windows XP Professional - Pentium (R) 4 CPU 3.00 GHz 2.99 GHz, 0.99 GB of RAM. Is it possible to upgrade the components without losing everything? I have years of designs and I want to get back into using it - purchasing a new cutter/plotter is not an option at this time. Other than the parallel port, it only has one working USB port. If so, is there someone in the Cincinnati area?
