Folks may remember back in October of last year in the thread titled "#5 Prop: Spock's 'CSG-1 Flight Computer'" that I discussed a small, handheld computational device used by pilots that surfaced as a prop in a few Star Trek
Well, there was a different but yet remarkably similar device that was also used in a few other episodes that I wanted to discuss in this post.
We see a different "flight computer" in a few episodes. Specifically, we see a Model B-1
Slide Graphic Vector Computer lying on the table top near navigator Dave Bailey in "The Corbomite Maneuver."
Like the CSG-1, this Model B-1 was made by Jeppesen & Company in Denver, Colorado. The Model B-1 Vector Computer was originally made by Warner Instruments in Chicago, Illinois in 1962, but Jeppsen bought the rights to the device and started making their own "Jeppesen Improved
Model B-1 Computer"--which is what we see on Star Trek
. We also see some unnamed Engineering-division crewwoman carrying one in the corridor in the same episode ('way over at screen left):
It also shows up a third time in this episode when a Command-division ensign carries one on the bridge:
We get a pretty good look at this device in "Mudd's Women" when Mister Spock uses it to make some computations:
But probably the best look we get at this thing is in "Who Mourns for Adonais:"
...and a blow up of the same view:
(You can see the big "J" in Jeppesen's old corporate logo 'way down at the bottom of the device.)
The Jeppesen Model B-1 Slide Graphic Vector Computer is much rarer than a CSG-1. These things seldom show up on ebay. They are about twice the size of a CSG-1.
As was mentioned in the earlier CSG-1 post, both Gene Roddenberry and Matt Jefferies were accomplished pilots, so it's very likely this prop was actually one of their very own personal navigation piloting tools.
What made the Model B-1 Slide Graphic Vector Computer nice as a prop--probably nicer than the CSG-1--was its larger size; also, it had a bright yellow ring--perfect for color televisions in 1966. The Model B-1 also has a red and black wind vector arm "spinner" on one side that adds a splash of color (although this "spinner" is really only barely visible in that one shot from "Mudd's Women").
Here are some shots of my vintage Jeppesen Model B-1 Slide Graphic Vector Computer
Here's a shot of the front (the "Vector Computer Side") with the Vector Card completely removed from the Circular Slide Rule "wheel" portion.
And here's a shot of the Circular Slide Rule and the reverse side of the Vector Card in their disassembled states:
Here's a shot of the Vector Card sliding through the Circular Slide Rule "wheel," just as it does in "Who Mourns for Adonais:"
And here's a shot of the Vector Card inserted into the Circular Slide Rule "wheel" in an "flipped" (backwards) position--just as was accidentally done in "Mudd's Women:"
Lastly, here's a shot that compares a larger "Navigator" size Jeppesen CSG-2 with a much harder to find Model B-1 and a somewhat hard to find smaller "Pocket" size CSG-1:
Anyway, between the B-1 and the CSG-1 and the push-button "Vulcan Calculator" prop, Mister Spock and the other Enterprise
crewmembers have plenty of handheld doodads with which to keep themselves occupied as they go about their important Starfleet computational tasks.
