Dambusters by South West Research Ltd. (UK) 1981

Factory conversion for Galaxians using a daughter card.

DBA1p, DB03 -> 2732 based on 1H
DB02 , DB04 -> 2732 based on 1K

DB05 to DB12 -> 2732 (code)

The game has an additional battery backed RAM that not only contains the usual 
NV statistics but also game play parameters. The RAM was originally loaded at
the factory. If the battery runs out then the owner must "contact the factory"
according to the manual. The game runs with bad RAM but can become unplayable.
