which is what you can do with DOSBox and a modern PC.I'm going to go with retro DOS gaming PC.
Do any modern programs and games even run on Win98 anymore?
Lots of metal shops and manufacturing facilities have programs that only run on Windows 95 or 98 that interface with old CNC machines and other equipment. Generally the software upgrades count in the 10s of thousands of dollars. Buying a machine that gets them another year or two of use is worth the $150.
