That's actually one of the last of the (Apple-branded) breed. Orange
Micro started making NuBus cards for Macs using 8088 (I believe,
possibly 286) and continued through Pentium and PCI, and Apple
started making NuBus cards for the Centris 610 using a 486SX-25,
later made a 486DX-2 66 card for the NuBud/PDS-equipped PowerMac 6100
& finally the PCI cards mentioned above for the 7200, 7300 & 4400 :).

Yeah, that's basically the problem with doing something like that
nowadays...the "I already have a PC" market is nearly everyone (and
getting nearer to everyone daily ;)
Just my thoughts,
