The wood boxes are quite beautiful.
The plastic case of pressurized cartridges is on top. | |
The thin box is for the small ball point pens,
the large box for all the other parts. | |
inside the thin case | |
felt lined compartments.
There are 2 tops for using the small pens
The empty holes are for the alignment reticules ("periscopes"), which are in the other box. | |
Pressurized ballpoint pens assure drawing starts instantly
from the point where the pen is dropped to the paper. I suspect these are identical to the Fisher Space Pen | |
inside the large case | |
|
Across the top: alignment reticules, high top for pressurized pens, the solenoid, the hollow top for drafting pens and felt tip pens, drafting pen nibs, and the container of Rapid-O-Eze pen cleaner. I believe a small spool of cellophane tape fits where I put the swabs. center: the drafting-pen liquid ink and boxes of spare drafting tips bottom: the felt tip pen adapter (flange with alignment hole), ballpoint pen adapter (thick tube), drafting pen barrels |
The standard size 1627 Model 1 was a Calcomp model 565 plotter and used 12-inch-wide paper (305 mm) with a plotting area of 11 inches (280 mm) … operating at 18,000 steps per minute. Model 2 was a Calcomp 563 and used 31-inch-wide paper (787 mm) with a plotting area of 29-1/2 inches (750 mm) … operating at 12,000 steps per minute.
In 1963, Douglas Englebart was working at the Stanford Research Institute. He set up his own research lab, which he called the Augmentation Research Center. Throughout the 1960s and 1970s his lab developed an elaborate hypermedia groupware system called NLS (oNLine System) … On December 9, 1968, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute presented a 90-minute live public demonstration of the online system, NLS, they had been working on since 1962. … This was the public debut of the computer mouse. But the mouse was only one of many innovations demonstrated that day, including hypertext, object addressing and dynamic file linking, as well as shared-screen collaboration involving two persons at different sites communicating over a network with audio and video interface. This demonstration has become known as "the mother of all demos" at the 1968 Spring Joint Computer Conference.
