KoalaPad: the mother of them all
Looking back in graphics tablet history brings us to the KoalaPad, the first ever digital drawing tablet for home computers. This device was first produced in 1984 by US company Koala Technologies and designed by Dr. David Thornburg.
The KoalaPad could be operated with the pressure of a pen stylus, or a finger for less precise work. It included two buttons along the top for operating additional software features.
Versions of this tablet were compatible with a number of 8-bit PCs, including the Apple II, the TRS-80, the Atari, the Commodore 64, and the IBM PC. It was packaged with a simple drawing application called KoalaPaint or Koalapainter, depending on the platform.
