I always liked to see the looks on people's faces when I compared our
VAX-11/750 (0.6 VUPS) with the *integer* performance of a Sega Genesis
(8Mhz 68000). The reason we could support 20+ users on the VAX with 8Mb
of memory was a) the 32-bit channel to disk and b) DMA outbound serial I/O
(a wad of Emulex 16-port muxes). Of course, it was more fun to be the
only user, especially when playing "Empire".
