Anyone know anything about this HP41 ROM?

Apparantly it has something to do wuth the US Postal Service.

What does it do?

Is documentation available from anywhere? Anyone?

I asked a friend ... It is an 8K ROM masked ROM, that is mass produced in a factory, versus a programmable EPROM. It contains various functions to collect metrics on delivery time, etc. for post office carriers.
