A HP 15CE keyboard handler bug?

About this newly discovered mode:

- This happens only with the 100ms rebound The Calculator Store supplied firmware ("enhanced") with checksum C6C6h and dated 2023-11-06
- If you connect to a PC with the cable, you will see the calculator in usb as HPb10II+. This mode is intended to back up the calculator user memory - but we're still missing the PC side app.
- To go out of this mode without resetting, press f-ENTER and "on" again.

So, it is a feature, not a bug. To be updated shortly...

I confirm, that this is one of "your" HP15CEs, flashed with the improved HP-16CE easter egg (unfortunately yet without the cable).
