So get the minimum memory config, and buy third-party parity SIMMS, a MUCH cheaper alternative, whether you buy min parity config from NeXT and add on third party, or buy reg. memory config and pull out the 8 SIMMS and replace with 9 bit third party. Too bad NeXT doesn't ship a "no memory option" [subtracting *their* price for the removed memory]- that was a joke, of course. Chow. -Bill- -- __________________Prof. William V.
