Well there is no HDD activity when I'm running the prog (ZX32 - a Spectrum
Emulator). But the sound stutters-- I'll dig out that ReBirth RB-338 to check
it's minimum refresh time. After sleeping on the card, not literally, I'm now
convinced its the Creative SB16 emulation driver thingy you find in System
-> Creative... area of Control Panel thats the prob. Its not a direct access
DirectX device.

But if the same prog ran fine with an old SB16, even a P75 CPU as against
my current K6-3/400 at full framerate, why should it fail now other than the
above reason. I can guarantee the Spectrum emu I run needs a DirectX direct
link. I tried playing Doom in DOS mode and it worked like a dream. Thats
simultaneous MIDI music and sampled sounds thro' the SB16 emulation.

Errm, is anything faster than an Athlon 600 available? I assume thats the chip
you mean by a K7, yeah Shawn?

Peeps with 15yr old PCs, where the video memory is in the B000-B7FF region?
In other words machines that would be worth more selling to the local museum
than a second hand store :-)
