ME and my dad own a hardware store in 1994 he bought a POS ABC Cadet stand alone computer from Servicestar now know as TRUE Value. It has been an excellent computer but it is getting real buggy True Value wants 20,000 dollars for new hardware and service is there any way to convert MS-DOS to Windows system it has always been saved on a Colorado Tape Drive but the back of the computer does have USB ports and could also link through serial port but don't want to damage anything so If any info or knowledge about this would be much appreciated or if any one knows where to buy a good almost new MS-dos system that could transfer data directly to I know some coding might be required any help please
