[laptop-accessibility] sdcard slot GPIO

[linaccess at yokoy.de]

hi,
the sdcard slots intended purpose is to use it with sdcards, shure. Would it be possible to use some pins as GPIO (generic purpose in out). If so, it would be easy to build very cheap hardware, for example a morse pushbutton for morseall (http://morseall.org/). With this it would be possible to control the machine with one finger.

The idea using the sdcard slot for GPIOs is reverse. On Linksys boards with openwrt you could use the GPIOs to implement a cardreader. Why not vice versa using the sdcard slot for gereral purpose I/O?
