I've created a page of useful reference data. It contains a list of links to other pages on this site which hold data useful to visually-impaired or blind Linux users/hackers.

The first two entries at the time of writing are a page which gives a textual tour of the Raspberry Pi single-board computer and a page showing tables of the pinouts of the GPIO bus on a Raspberry Pi.

I intend to add other stuff like the commands unique to the Emacspeak variant of Emacs.
