Is this true or just ``rumor''. Well it's the first time I've heard such a rumor. But in any case, how do you get only 64Mbytes w/4Mbit DRAMS? I believe the current DRAMS in use on the SIMMS are 1Mbit with a total system capcity of 24Mbytes. If 4Mbit DRAMS were used (in the same space as the 1Mbit ones), I would think it would come out to 24Mbytes * 4, or 96Mbytes? Maybe there is a limitation w/the address bus? Sounds nice, but also sounds expensive :-) /--------------------------------------------------------------\ |Jeff Michaud michaud@decwrl.dec.com michaud@decvax.dec.com| |DECnet-ULTRIX #include | \--------------------------------------------------------------/
