I think you could be right. My win95 machine has 2x40gig drives, 1x cdrom, 1x cd burner. The bus speed of win95/98 is limited to 66mhz, but I got a patch from Microsoft and bumped the bus speed up to 100mhz. James, I'm not sure what you mean with the system 7 stuff. I got it originally before win98 came out, it was a 300mhz pc then, the processor a K6. One day the fan died, and the processor overheated, blowing itself and the motherboard. I got a new motherboard and a k6-2 processor which is what I have now. I leave the case off otherwise it gets too hot and hangs windows. And, back on topic, I successfully applied a diff patch, and compiled mame 0.101u1
