An example of this is found in the All Electronics catalog..
NatSemi 8048 (or maybe 8049) CPUs with programmed ROMs are $.50
each. Simply strap the EA (External Access) pin true and use an
external EPROM+latch - it is equivalent to an 8035L, runs on an 11 Mhz
clock, leaves 16 pins of I/O after connecting the EPROM.
