JDR Microdevices should have the EPROMs you want.  They are fairly cheap, have
a good selection, take VISA, ship very quickly, and their minimum order is at
most $10 (if any-- I go to the retail store now :-).  They are in San Jose, CA,
phone 800-538-5000.  There is a different 800 number in California which you
can probably find out from 800-555-1212.

The only manufacturer I know of off-hand for 70ns DRAMs (actually 60ns and
80ns) is Inmos, and that for 256kb only.  Their US headquarters are in
Colorado Springs (303)630-4000, and they can undoubtedly tell you who stocks
their parts.  There are several Japanese manufacturers with 80ns parts now,
but I am currently unaware of any faster than that.

I assume that you want to build a drop-in SBC for your PC.  If you are
attempting to speed up the PC's CPU so much that you need 70ns DRAMs for
main memory, you will undoubtedly find that the rest of the machine will
collapse miserably.  Besides, I am unaware of any 16MHz 8088's. :-)
