Wang 360KT Trig Video

This is a video clip of a Wang 360KT (Trig) keyboard/display unit connected to a Wang 360SE electronics package, performing the sin of 45 degrees, followed by the arcsin of the result. The video has an artifact in the display due a beat frequency between the refresh rate of the multiplexed Nixie tubes of the 360KT, and the frame rate of the video camera. This manifests itself as an area of dark Nixie tubes slowly moving left to right across the display.

The video is approximately 30 seconds in length, and is in MPEG2 format with audio, compatible with Microsoft Windows Media Player, as well as most other video playback software. The total length of the file is approximately 5 Megabytes.

The video shows the display of the machine as it performs the following operations:
