if they are suitable for it, ask Motorollin to blank them and put the 3.9 stuff on them.

Sorry, won't work. The Amiga's kickstart chips are ROMs, which means they are not programmable. You need EPROMs if you want to put 3.9 on them.

Aren't EPROMs the really oldschool ones with the window to erase them with UV?

That's right.

If so wouldn't EEPROMs be better since they can only be wiped with the proper equipment?

Yes, but I can't find an EEPROM which is compatible with the Amiga's ROM socket. I was thinking of trying to find an EEPROM which is not pin compatible with the 27C400 EPROM, and build an adapter board so it can be used in the Amiga.

Anyway if someone were to pay you for materials and time etc. would you be willing/able to make some more 3.9 ROMs?

Sure, but I would need an original 3.1 ROM and 3.9 disc sent to me first to confirm that you have them, and I would make the 3.1 chip unusable so it cannot be used in another Amiga.
