There are 2 ways of looking 1st and 2nd generation Power Macintoshes. One way has to do with the expansion card interfaces:
1st Gen have/use NuBus cards, sometimes via a PDS (processor direct slot) adapter. NuBus had been used since the Mac IIs and Quadras. The 8100 had NuBus; the 6100 series required a PDS adapter (although there are PDS-only cards). 2nd Gen Macs use PCI (peripheral connect interface) cards, which is an industry standard used in all current PCs and Macs. Examples of possible cards include network, SCSI, Firewire, USB, TV/radio, and so on. The other way of considering generations is by processor type. 1st generation Power Macs used PPC 601 chips. This includes the 8100 & 6100 series. 2nd gen use PPC 604 chips (and, perhaps, 603s). Examples include the 8500 & 9500 and 8600 & 9600. 3rd generation use G3 (and G4) chips. Apple supports the use of OS X on all 3rd generation machines (more or less).
