David,

In simple terms an IPC is about the equivalent of a SPARCstation 1+ and an
IPX is about the equivalent of a SPARCstation 2. For the exact difference
see the specifications below. If you are interested in buying one you might
check with the Linux General Store. http://www.linuxgeneralstore.com/

The following specifications were obtained from The Sun Hardware Reference
FAQ Part 1.

                        512M/process virtual; 64K write-through cache,
                        direct-mapped, virtually indexed, virtually

                        Essentially same as SPARCstation 1, just faster
                        clock and improved SCSI controller. First
