Hello Forum Members!

I've taken the advice of @Dave Frederickson, and purchased the HHC 2021 flash drive, specifically for the HP-10C ROM file.

I've been playing with Nonpareil, so I loaded the ROM file with the Nonpareil 11C...

A few observations:

1. It passes the self test.

2. The keyboard test displays the exact same segments, while keys are pressed in succession, as other Voyagers Series, but final display is off (should be 10).

3. Clearly, the segment mapping is different than other Voyager Series models, as below initial power on display (0.0000):


I'm hoping members can offer insights as to the reason, and possibly offer solutions for remapping the segments in the Nonpareil code.

Thank you!
