The Springboard expansion slot were produced on Handheld Computers
developed by Handspring, how ever Handspring no longer makes Springboard
modules. Springboard cards are used for more then just Flash memory
expansion. Springboard was designed using the same 68 pin header used on
the PCMCIA PC Card, but the pinout is different.
The pinout table below defines the main connector pin out, how ever there
is an expansions slot that is not yet shown on this page. Handspring uses
the industry standard Palm OS as its software platform.
Xilinx has an Application Note covering CPLDs as used on the [xapp147.pdf] Insight Electronics Springboard Development Card, dated
2002.
The SpringBoard card dimensions are: 67mm x 54mm
