I am getting a IIci soon (hopefully) and I am trying to clarify three memory
questions:

1) Are the configuration rules for the IIci RAM banks DIFFERENT from the other
Mac 68030 machines?  According to the Byte review, the IIci does not require
contiguous memory installation.  Does this mean that I can mix and move memory
around in the 8 SIMM slots?  Can I have a 3MB machine?  Can I have two 1MB
SIMMS in the A bank and 2 in the B bank?  On the other 68030 machines the
allowable memory configurations are 1-4-5-8 MB given the rules that "bank A
must be filled", "bank B must contain 0 or 4 SIMMs" and "bank A must contain
equal or higher density SIMMs than those in bank B".  What are the rules for
the IIci?

2) Will the IIci run more efficiently (faster) under Multifinder if I put
"some" RAM in the A bank and "most" in the B bank.  According to the Byte
review the video system locks out the CPU access to the A bank for 600ms when
it refreshes.  Apparently Multifinder loads applications in the B bank first
so these would not be slowed by this recurrent lockout.  What about when
System 7 comes along - where should memory be then?

3) Do I have to put 80ns RAM in the IIci?  We have a (growing) bunch of 120ns
and 150ns 256K SIMMs here.  I suspect that I do have to use 80ns RAM... so
where is a good source (price, reliability...)?

Please e-mail me directly with any comments/answers in addition to posting
them.  Slogging thru this news section is too time consuming.
