I did not find any POKE in my old AUTOEXEC.BAS file, so I can only assume that, back in the day, I must have swapped out the ROM chip of my floppy controller. If I did, at some point I replaced it with normal DECB and have no idea where the EEPROM went.

I am pretty sure I also remember having a Smartwatch chip installed, and I can find no proof of that either.

Mandela Effect! :-)

Thanks for the info. The explanations on how it is supposed to work make more sense than my memory, so I am siding with the explanations.
