I wonder if my 32K RAM is actually two for 64, or one32K and a different ROM. odd one would be marked and the other not.

There are 5 other chips besides the Math. All appear to be the same, except for the center bottom. it has a different solder jumper, than the other 4. its the same on.my other 71B as well.

Right you are I thought I saw something in one of the earlier pictures that made it look different.
