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.

        Memory:         64M (40M?) physical with synchronous parity,
                        512M/process virtual; 64K write-through cache,
                        direct-mapped, virtually indexed, virtually
                        tagged, 16-byte lines; 50ns cycle
        Architecture:   sun4c
        Notes:          Code name "Campus B". 1M or 4M x 9 30-pin 100ns
                        SIMMs, in four banks. 1.44M 3.5" floppy.
                        Essentially same as SPARCstation 1, just faster
                        clock and improved SCSI controller. First
                        supported in SunOS 4.0.3c.

                        version). Picture of Hobbes (from Watterson's
                        "Calvin and Hobbes" comic strip) silkscreened on
