This is very very possible. What I wonder is whether the onboard chipset is slower than the ISA bus - and whether using an external card would eke out a tiny bit more performance. Apparently the ISA bus can stably run at up to 8MHz. It's not on-point but I found this thread that discussed SCSI controllers that was kind of interesting: http://www.vogons.org/viewtopic.php?t=36001 http://www.vogons.org/viewtopic.php?t=36001 This project is really awesome btw.
