Echoed awe :-)  What's the emulator written in?

FYI a p90 is a Pentium running at 90Mhz (turns an unpleasant shade of green)
Is is one that's fixed?  Pentiums have an interesting fault in the fdiv
instruction that means it's a little less accurate than it should be.
(Intel asked a Pentium what 486+100 was and got 585.9997, so they changed
the name :-)  Credit for that one goes to someone on a usenet group)

I'll have to keep an eye out for this one...

PS.  Do you want me to drop the .sig when I post here.  It seems a bit
silly to keep telling you all that bbc-emu is the list :-)
