The Key Tronic KB5153 was $400 in 1985... I got mine for $4 this year. :-)
a touchpad??
do you have photos?
edit: this is a nice passage:
"Keyboard design is one of the most important considerations when shopping for a computer. The keyboard is usually the only hands-on part of the system, and a balky or awkward setup can produce physical as well as mental strain.
Some people prefer a crisp key response, while others like a spongy touch. Some enjoy the positive feedback of an audible click when each key is touched, while others prefer silence. Some like hair-trigger keys, while others like stiff resistance. Unfortunately, many buyers think they have to put up with an uncomfortable keyboard to get the computer they want."
