I used to program my 29f032 chips with my ADP-082+ADP-077 adapter combo, with the -082 jumper 5 set to v1. This worked nicely.
Now I have another batch of seemingly equivalent 29f033 chips that do not program on this v1 jumper setting, but which works nicely on the v2 setting.
Since I need a in-circuit programmer for boards on which the eeprom is already mounted I'd like to find out what's different about these jumper settings. Does anyone know?

Did you find out?
It should be easy to trace the board.
