It appears LAZER-TRON made arcade or slot machines. Any interesting story about how you came across this board? I wonder if it did come out of such an embedded device. No, just got it off of eBay. I got it booting with a Pentium Overdrive PODP5V83 CPU and 2GB Compact Flash card. Seems to be working …

Looking at the patch you made, aren't those values already set ? I think you could break the routine at 377, but I'm no expert. As far as I can tell, the changes only stop the device driver from waiting for keyboard input, which was built into the shareware version. The rest of the functionality …

My personal opinion is that the Pentium Overdrive is in fact a super scalar CPU. A regular Pentium is going to have a 66MHz FSB and 64-bit path to memory. Those are both cut in half in the case of a Pentium Overdrive. That is a lot to overcome when running benchmarks. Much like an 8088 vs 8086 or a …
