My regret list is quite long but at the top are: 1. Three Apple 1 computers including one in the box with all the extras and a personal letter from Steve Jobs telling what keyboard to use with it. 2. A working Bendix G-15 that was in my classroom in the early 1970's. 3. A working Burroughs B-3300 4. A Univac Short Code manual from 1952
And soon I can add to the list my entire collection as it is moving to a new home next month.
