7854 ROM replacement issues


Martin Whybrow
 

My 7584 is suffering with ROM failure, so I decided to buy some 2364 to 2764 adapter boards and fit 2764s instead; however, the adapter boards are too long and overlap the adjacent ROM sockets. Given that this seems to be a popular mod, how have people managed to fit 2764s on adapter boards?

It does appear not to be the ROMs after all, they all read and verify correctly for rthe -01 revision.
