I also found that an 8' floppy disk existed and the 8' 2S/2D format had a capacity of 1.2MB and was supported in DOS 2.x
I have never seen an 8" floppy drive for PC

Re: v14 compatibility & bug list (WIP)

Not sure if this a correct topic. The 1982 game Paratrooper not working correctly on any XT-class machine. It has no sound on an IBM PCjr and keyboard control problems on other XTs. The PC speaker in PCem v14 sounds also garbled a little in this game. We have to be very careful on the PCjr - many g...

BIOS / Chipset compatibility

I opned the model.c file and saw that both the WinBIOS and AMI486 clone use the same chipset, of course, both BIOS files are different. Now, the question is: If I dump a BIOS from a 430VX chipset motherboard, should it work as a replacement alternative for the "Award 430VX PCI" motheboard? I dumped ...

If I run it with a 286 or better, below the castle it says "PRESS ANY KEY" and the game works fine. The game shoud run on any XT class system, so my guess...

I didn't say GF2 needs to be added to PCem. I just said that both games work fine with GF2 64mb. If we get past Voodoo2 that will be a success.
Ok, I misunderstood. Voodoo3 is very likely to be added to PCem, however, the performance is near the Voodoo2 SLI we currently have
