Murphy's police waste no time around here.  I ran across a chip today
with no standard markings.  Says 
014
32500
AH8749B

It's from a 1227747, so I read it as a 2732, and it looks ok.  Won't
try to program it until I need to.  The 748 Eproms I've viewed have
been the same size.  Again, that's so far.
