Can anyone enlighten me on the following?
I just picked up a S/N 1143 calculator. Thought it might have "the bug", but it doesn't. I have a S/N 1249 calculator with the bug.
Both have raised dot on the 5.
The back label on the earlier calculator matches one I have starting at 1302. These labels state on the top HEWLETT-PACKARD HP-35 INSTRUCTIONS whereas the '72 unit only has HP-35 INSTRUCTIONS. Does this indicate the unit was sent back for repairs and the different label was applied?
I do notice the battery compartment is two piece and can see the board through the slight crack.
