HP-41C Logic Board Identification
I recently acquired two logic boards that were removed from unknown HP-41 calculators. Is there a way to determine which model they came from C, CV, or CX based on the numbers on the back of the board?

One is:
00041-60001
J-1935

The other is:
00041-60104
A-2035 LEM1

Thanks for your assistance.

Have a look here and look for similarities.
