[comp.sys.atari.st.tech] DRAM Speed and Manufacturer

ric@mcrware.UUCP (Ric Yeates) (08/30/90)

Netlanders,

    I am going to upgrade my Aerco board from .5M to 2M.  All I need is
the 1Mbx1 DRAM chips.  My question is: Do I need to get relatively fast
chips or is it not going to make any difference for a 68000 system? If
anyone has any experience in this area, I would appreciate the help. 

Thanks,
    Ric

P.S.  I'm looking to get 120ns Intel DRAMS @ $6 if they don't need to be
any faster.

In general, anything 150ns or faster is OK for memory expansion in an ST.
The Intel 120ns DRAMS you're getting should work fine.
