Probably a very long shot, but ....

Has anyone with a W65C134SXB and the 128KB EEPROM managed to program it in-situ?

I think it's possible (lets quietly forget the banking for now - I'm just after a proof of concept) from code running in RAM..

Cheers,

I've not tried programming the flash on my 134SXB yet but it should be virtually the same as the 265SXB. My 265SXB hacker code is here:

The E, W and X commands erase and program the flash.
