The KAYPRO-10 in action. It had a 10 MEGAbyte HARDDISK!!
For that time it was AWESOME!!
It had a nice menu, so that you just typed a numberkey, and the corresponding menu-entry would start.
That was sophistication in the early eighties.
What a contrast with today (2012) where you just yell to your iPhone 4s, and get what you want...
