[comp.sys.att] 120 vs 150 ns DRAMs in Combo Board

cliff@ethos.UUCP (Cliff Elam) (07/01/87)

Does the title say it all?  If I have 0 waits on my 10Mhz bus
I assume I need 120ns (or better) but if they're 1 or more
waits I suspect I could use 150's.  Since I'm going to be
doing my own socket installation debugging would be a bear,
so: HELP!!!!

Also, is this bus 8/16/32 bits wide?

If you buy a memory expansion card with RAM installed, it's got 150ns.
I've heard that there are no wait states on the motherboard, but it is
possible that it's a different story on the expansion bus.  I'm not in
a position to know.
