Excellent collection of interactive devices spanning the last 30 years. Unfortunately both Casio and Sharp’s contributions in the late 80’s are under represented. Consider the Sharp Wizard’s OZ-7000 expansion card interface that provided touch pad interaction with ROM based applications.
Some great photos of computer related designs from the 90’s. I particularly like this quote “There is no invention out of the blue, but prospecting, mining, refining and then goldsmithing to create something that’s worth more than its weight in gold.”
