A review of Dave Hitchins New Advanced Plus 5 (AP5) cartridge for the Acorn Electron Plus 1 expansion unit. I replace my ElkSD Plus 1 and ATI with ABR for an AP5 to provide the functionality of both products in a single cartridge.

As always, many thanks to everyone on StarDot, especially Dave Hitchins and David Banks, who helped sort out my various odd problems.
