W65C134SXB and programming the flash eeprom?

Post by drogon »

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,

-Gordon

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.
