The Opus Challenger 3-in-1 combines a 5.25 inch double sided 40/80 track disk drive, a double density disc interface and a fast solid state RAM disc in a single unit, much the same size as a double disk drive unit. With 256k built-in RAM, which can be expanded up to 512k, plus the double sided, double density 80 track drive, the Challenger can upgrade the memory capacity of your BBC Micro to 1MB.
Unusually the Challenger does not connect to the BBC's floppy drive port but connects to the 1MHz bus and includes a pass through socket so devices can be daisy chained. The Challenger has a WD1770 disc controller.
