Any information on HP-41 "Aviation AV1" Module?


I picked up an "Aviation AV1" module for the HP-41 a year ago, and have no documentation. It is labelled "82500A-A09 ADM SYS INC @1981 ID 31 SINGAPORE"

Does anyone have any information on its functions?


Hi Dan,

Do you suspect that it is different from the original Aviation ROM for the 41?

I have that one - labelled 00041-14008 'made in singapore'

Try XEQ 'FM' and if it returns a display that says 'D S T FF F' it is what I have.

Be glad to send you the user info if you like - bought the whole shebang still in shrink wrap from the HongKong aerospace museum in January.
