When you say 18 -- a assume you mean 2 SIMM or SIPPs, where each
SIMM/PP have 9 chips.  In other words you have 2 1Mb SIMM/PPs and
would like to add 2 256K SIMM/PPs.
 
The answer is NO.  You cannot mix different SIMM/PP memory size in
the same bank, one bank being 4 SIMM/PP.

Please note that the issue here is not mixing 70ns and 100ns DRAMs.
