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.
