Joe, the ebay seller of the ROMs is going to confirm on Monday that they are indeed the TMS2564JS and then ship them they'll be here pretty fast.
My current computers and laptops do not have serial or pci connectors. USB is all they have. No easy top find a USB based programmer that also reports that it has 25v VPP. I may end up taking you up on the reprogram effort in a few days when they arrive.
