Hi members

I got an old PET with 6540 ROMs and these ROMs seems to be damaged.

Some pins a broken and after I have soldered a socket unter the ROMs they
continue not in working condition. Some times aftyer power on the normal
prompt appear but most some random is spread over the whole screen.

My question is, is there a replacement for the 6540, maybe any EEPROM or
PROMs type ?
On the internet I had found some hints for an adaptor but I couldn't find
the source or schema.

Can everyone help or inspire me

thanks and Regards j.
