Looking at playing doom at 386 or 486 speed. I'm going to do this once I get my hands on one as an experiment, just wondering how it would also go for things in general.

I imagine Doom would be capped between 10-20 fps just like on a 486 with ISA video.

Will the ISA card work at all in a p3 motherboard?

I have a p2 350 with isa slots if it doesn't, will be interesting to find out. I've bought about eight different sound cards because I recall having one with midi better than OPL3, but not as good as wavetable.

Of course it will.

Some of these early video card BIOSes are buggy and get in trouble with a too fast CPU.

There is always a chance that something won't work together but in general ISA vga cards should work in a P-3 system.

In general the 8-bit ISA VGA cards are very old and the BIOS was not tested with fast CPUs as they just didn't exist. I have quite a few models and some don't work on Pentium2-class boards. No problem if you have a variety - but if you have to buy one from Ebay and find it doesn't work there will be disappointment.

Also keep in mind that it will only slow down the drawing routines of a game. Other time-critical functions that may exist, such as badly implemented soundblaster presence check or game logic will not be slowed.

I don't have any 8-bit ISA VGA cards any more so I can't test it. But the question was ISA and I can say for 16-bit ISA cards.

Title of this thread says:

How much would an 8-bit video card cripple a pentium 3?
