The 8584 is the only one I've ever seen. I researched the part but
have not used it yet.
Can't you force a CPU wait-state on this one peripheral to make it

27C64 is an EPROM, CMOS, 64 K bits (8K x 8).

The 20 usually means 200 nanoseconds access time.

64kbit, i.e. 8 bit x 8k Byte, EPRom. 20nS is incorrect, too, usually
those -20 parts are 200 nS. (About the fastest EPRoms get is, oh, 45 or
50 nS, that I know of.) See (for example)
