We offer the flashing of new firmware for the 10bII+, 12c+, 20b and 30b.
These calculators have a port that allows the user to flash a new firmware. For that, a special cable is needed.
Once the flashing has been done, the original firmware disappears and cannot be recovered. Hence the calculator guarantee is no more valid.
As there are several versions available at a given time, the customer has to supply via email the desired firmware to flash. The customer has to be aware that the firmware may contain bugs - of which TheCalculatorStore.com cannot be made liable. We do not offer currently key overlays or key printing - additional information can be found at www.hpmuseum.org, and you can see more information in the video below:
If the software provided is the wp34s, 10€ of the 15,00€ value will be donated to the project
The offer only applies to new calculators bought at TheCalculatorStore.com
