Springboard Expansion Slot

The SpringBoard Expansion Slot was a versatile expansion slot devised for Handspring's range of Palm OS PDAs.

In 1999, the flexibility and expandability possible with SpringBoard modules was unavailable in other handheld computers. The innovation earned Handspring the PC Magazine Annual Award in the Handheld category for its Visor series. The PDAs available from Palm had been less flexible, and this limitation contributed to the splintering off of many Palm founders in order to form Handspring Inc.

This proprietary hardware standard supported a plethora of accessories. The interface inspired many creative products because it made it possible to use the PDA as a flexible interface to otherwise technically difficult to manage sophisticated hardware. Among the many available modules were auxiliary memory, game plug-ins, GPS navigation receivers, cameras, GSM and CDMA mobile phones, versatile infrared remote controls, wired and wireless network interface cards, Bluetooth modules, MP3 players, cordless phones with answering machines, and voice recorders.

Distributing software in plug-in modules was also seen as the next big thing in software protection, with an implementation very similar to game cartridges in entertainment systems. However, the impractical requirement of carrying around multiple modules, not to mention the potential impact on delicate pins, prevented widespread adoption.
