put finger to keyboard and composed:

I bought a Pitney Bowes A510 digital scale on Ebay originally just to
use it for weighing shipments to calculate by hand what the postage
should be (goes up to 10 pounds in 0.1oz increments).

However this scale has a built in price calculator - it'll show what
the $$ should be to ship something. Problem is the rates are not
updated ( for example first class 1 oz is $0.33 instead of $0.37). It
would be nice to use this function.

Rates are stored on a pluggable card containing a 27c64 ROM chip.
I've dumped the code, looked at it in a hex editor but don't know what
bytes to change, where the checksum is stored, etc.

Anyone have a current hexdump of the rate prom from a Pitney Bowes
A510 or similar scale? Or know how the data is arranged so I know
what bytes to change to update to the current postage rate?

TIA
Dave


I'd be interesting in looking at the hex dump. You would need to
provide a list of the scale's rate data, though.
