Another stupid flashing cable question HP-30b / HP-15C CE

I'm not sure but isn't the power-on name user-programmable? Maybe it defaulted to "Pauli, Walter" at some point but is now blank ("Erased") unless you set it.

If so your previous reflashing attempts may've been partially successful showing "Erased" (the AT91SAM7L128 bootloader doesn't do it). Or the calculator wasn't reset/power-cycled (the display should be blank after erasure/reset per the HP-15C CE).

If the above is accurate "Erased" was a bad word choice IMHO. Perhaps "Name?", "SetName" or "Default". "Erased" implies that the flash is erased (technically the calculator name is) which made me think that the bootloader was custom. It isn't. A generic serial bootloader in ROM per the device datasheet.

Yeah. I scan stuff I download with at least one (usually multiple) virus scanners. In the case of SAM-BA 2.16 (works with the HP-12C+ and HP-15C CE) I got it from the official Microchip website. I scanned it too before installing it in (deleted after use) virtual machines (VM's). That said I suspect that few do that. You can't trust much these days "They really are out to get you!".

FYI that MySamba program was written using Delphi. A "bare bones" application that even runs in Windows 2000.

I think rprosperi might be correct. MySamba seems to be a WP34S project creation. SAM-BA was an Atmel (now Microchip) program. I've been unable to determine what the last version of SAM-BA, that supported the AT91SAM7L128, was. I cannot find any download link to anything prior to v2.16. Some Chinese sites claim to have it but... Microchip doesn't. Not an issue for me but MySamba may be the only option nowadays if you have an old calculator.
