Re: Is drive sound emulation possible?

I'm tempted to suggest that you add the sound that a real drive makes when its bearings finally wear out. Or the sound that old capacitors make when they finally burst and explode. Having had an old capacitor explode and hit me in the forehead recently, I suspect this has a high chance of triggerin...

Re: Is drive sound emulation possible?

That's a noisy hard drive you have there. The speed variation sounds pretty good to me. For floppy stuff, it might be (well, probably is ) worth looking at what I did for B-em, of which you've already found vestigial references. Code is at https://github.com/stardot/b-em/blob/master/src/ddnoise.c (u...

Re: Emulating an Amstrad PC5286

I believe the PC5286 did use IDE - Amstrad were using it as early as the PC2000 series.

Re: Emulating an Amstrad PC5286

640kb conventional + 384kb XMS looks right for a 1 MB machine. I don't know if the PC5286 enabled Shadow RAM or not; disabling it will give you more RAM, but run the machine a bit slower. If you were to get a real machine, you can dump the BIOS through DEBUG.EXE. The following commands should dump t...

Re: Is drive sound emulation possible?

This isn't currently implemented, but has been on my list for a while. Much of the infrastructure for floppy drive sound emulation is already present, I just haven't got round to finishing it off.

Could this be due to missing bios systems (i.e. nobody has dumped a PC5286, etc.)
Basically this - if the BIOS hasn't been dumped then it can't be emulated. I'd be interested in emulating these systems, though due to other commitments it would probably be some time before I could look at them.

If we can identify the nature of the erratic 2D line rendering then it should be emulated, yes. I wouldn't be surprised if this is a hardware bug; someth...

Yep, there's a bug. PCem isn't forcing a screen refresh on writes to the per-pixel scroll register (0x3c0 index 0x13/0x33), which is only obvious if the start address isn't changed and there are no writes to video memory that frame. The fix should be fairly trivial...

Performance won't be brilliant, the 8550u only runs at 1.8 GHz. I'd guess around Pentium 90 or so would be about as fast as you could get.

Re: 266MMX slower than P70

Because neither chip actually shipped? Desktop Pentium MMX peaked at 233, 266 and 300 MHz chips don't appear to have ever been sold. There is a (rare) _embedded_ PMMX 266, but that appears to be the same Tilamook core as used by the Mobile chip.
