I'd thought the same thing Matt . Had seen RFM's for sale on ebay etc. with the title as "Bally RFM.." and thought it was either a typo or them trying to get people confusing it with AFM . Hadn't really noticed that they were badged as Bally until now . Weird.
That would explain why RFM was marketed under Bally seeing if was basically a concept copy of AFM to quickly get RFM on the market for P2000
