I've been using 2732As, and now find out they are "supposed" to be 27c32s?.
Now on the 27128, 27256, 27c128, 27c256, what do I do?.  Is there a
difference
in the 27128 to 27c128,  and my lil book shows a difference in programming
pins, and voltages from 27128 to 27256's.  Is there a "safe" way to try and
read 
one first?.
