Rumor has it that Jon Auringer may have mentioned these words:

Where's the fun in that??? I was thinking: Skeet. ;-)

Otherwise, you're right - every benchmark I'd ever seen with those showed
they were slower by 10% to 25% compared to a non-combo board.

Also, IIRC: Vesa Local Bus was quite a bit faster than PCI of the same era
(PCI max a the time was 33Mhz, VLB was 40Mhz, maybe faster) and the slots
were still 16-bit ISA compatible -- but they were a 'licenced and
practicing bitch'[1] to insert and remove.

Once again, the physically simpler but technically inferior standard won
out... ;-)
