My Next came last December with 16 meg of ram. According to the "monitor" in 1.0, the first 8 meg are page mode simms, and the second 8 meg are nibble mode simms. The question is,why are they mixed like this, and does it hurt the speed of the machine that they are not all page mode (or not all nibble mode, for that matter)? Any clarification would be greatly appreciated. Nick Katz nmk@math.princeton.edu

Any clarification would be greatly appreciated. Nick Katz Just a thought... I'd be interested to hear performance results from a main memory intensive test with these three memory configurations. Care to try? 1 - 8 meg. page mode 2 - 8 meg. nibble mode 3 - 4 meg. page mode AND 4 meg. nibble mode =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Edward McClanahan Hewlett Packard Company Mail Stop 47UE -or- edwardm%hpda@hplabs.hp.com 19447 Pruneridge Avenue Cupertino, CA 95014 Phone: (408)447-5651

For those of you who are thinking about upgrading memory in your NeXT, I tried out 4MB of 100 NS RAM from one of the mail-order places in the back of MacWeek. $89/MB, Ca$h on delivery, no PO's or plastic, but they slipped right in, and I rebooted to a 12MB machine that's been humming along just fine. They were page mode (according to what the monitor told me). This week's price was $83/MB and the vendor advertises "prices subject to drop without notice!"
