PS-9000_P1.jpg (350695 Byte)The PS-9000 Back-up Memory Module was designed for the PS-9450 and PS-9500 TimeRunner Organizers. It backs up the entire TimeRunner memory for storage and safekeeping. Within one year the PS-9020 Link Software was introduced to save the memory to a file on a IBM AT-compatible PC.

The PS-9000 Back-up Memory Module was sold in Europe as IS-8050 but works with the IS-8200 and IS-8400 Digital Planner, too.
