Koala Technologies Corp.

The KoalaPad was a popular graphic tablet on the 8 bits computers of the early 1980's (Apple ][, C=64).
The KoalaPad invented by David D. Thornburg.
The KoalaPad was the first touch tablet for computers, and we had a heck of a time convincing potential customers that they could draw pictures on the computer with a pen!
