HP41C Logic Board Identification
I recently acquired two logic boards that were removed from unknown HP41 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: 0004160001 J1935 The other is: 0004160104 A2035 LEM1 Thanks for your assistance.
