Having decided to upgrade my Heath/Zenith Z100 to suport color, I
delved into the tech manuals and found that I could use 64K DRAMs
instead of the 32K DRAMs supplied by ZDS, assuming this is 
advantageous my question is : must I use the MCM6665 DRAM specified
in the manual, which are $6 each, or can I use the 4164 DRAMs
I see advertised for $2 each in Byte. Apparently they are
both 64K 200ns 5V DRAM, but can I replace one with the other?

                       Thank You
                       Dave Benz
