help me decide a DOS pc motherboard

SCSI was always faster than IDE, but it comes with its own issues (drivers, for one). I will look out in my garage and see if I still have some old IDE ISA cards. At one time I had dozens of them but I think I tossed most of them. The ones I have had IDE, floppy, parallel and serial connections on them.

thanks flack, LMK if you find anything. acually this is a shot in the dark but if you have an AT PSU (with a switch, i think they all have switches) and a 3.5 inch internal floppy drive with a white face i'll buy them off you.

has anyone ever seen a ISA PS/2 mouse card or am i stuck with getting a serial mouse? its no biggy just curiouse.
