Comments
The product number is 04 for the 83+, 0A for the 84+. Other product numbers are defined for the other Flash calculator models. The product number is also the freeware OS key ID, as well as the last byte of most other key IDs.
This is not quite the same as the first three digits of the PROD ID shown on the About screen (though it may have been so at some time in the past.) The third digit shown on the About screen is the OS's hardware compatibility level, not the actual hardware version.
