At one time 1M dynamics were much less expensive compared to static
RAMs.  That's when the idea of more than 1MByte in a PC was considered
absurd.  If you want to put a SIMM into a PIC you need to think 16Mbyte
minimum and then you can get the SIMMs for under $50.  What a PIC would
do with that much memory I'd love to hear about.
