RE: Charger Specs for Rockwell 74k Calculator
Maybe the same psu could have been used with other UK built models in the range that were powered by regular dry AA cells. A switching jack plug would take them out of circuit. Hence, battery "eliminator".

It is interesting that the psu is dual badged as "Sumlock Anita". The calculator shown (built in Japan?) was from the transition period as Rockwell International waded into the UK based company, just before asset-stripping the place and closing down calculator production. Like Commodore, they looked into their crystal ball and saw that calculator makers were about to get badly burned.
