I have (4) SIMMs that were originally in a Mac Plus that I'd like to put
in a Mac IIsi.  (2) are 100ns chips and (2) are 80 ns chips.  In the Plus
the different speed chips were in different SIMM banks.                          
My question is, is there a problem with chips of two different speeds residing
in the same SIMM bank of a IIsi?  (or a II, IIx, IIcx or SE/30 which also
have 4 SIMMs per bank and can use 100ns SIMMs).

Bank A of the IIsi is the 1 MB soldered on the board and Bank B consists 
of 4 SIMM slots.  The Apple literature says the IIsi can take 100ns chips
no problem but I am want to know if mixing SIMM speeds in the same bank 
will cause troubles.  

Response here or by email is fine.  Thanks in advance.
