Description

The object consists of three components: a metal stand with a metal holder bolted to it, a monitor sitting on the holder and a keyboard sitting on the stand. The keyboard has a white and green sticker attached to the back with the name "Memic" [OEM?]. The keyboard has a white sticker attached to the bottom with the name "Computer Communications, Inc. Inglewood, California" [OEM?]. An LLNL blue dot is attached to the top of the keyboard. On the front of the keyboard are 18 toggle switches (labeled from 18-35) apparently used to set the starting address. Also on the front of the keyboard are multi-position switches labeled: 7-bit ASCII, 8-bit ASCII, 7-bit TTY, OCTAL, Read Recycle, Read Single, and Modify Write. Behind the front panel of the monitor is an embossed label reading "Sony." The monitor was apparently created as a TV set: it has an attached flip-up antenna. The stand measures 27 in x 22.5 in x 17.5. The keyboard measures 4 in x 17.25 in x 8.5 in. The monitor measures 13 in x 12 in x 12 in and the screen is 10.5 measured diagonally. Pieces of paper attached to the stand and monitor contain tabular information involving transceivers and disks. According to computational physicist George A. Micheal, the TMDS were developed and used at Lawrence Livermore National Labs "to provide graphics to all our computer users at as low a cost as possible." These units were used with the PDP-6 and CDC 7600 Octopus System. See more at http://www.computer-history.info/Page4.dir/pages/TMDS.dir/index.html.
