Professor Eric Laithwaite (1921-1997) of Imperial College London demonstrates the difference between magnetic and electro-magnetic motors. Examples futuristic - include minute pump that can fit inside human tissue and a huge test rig to help develop high speed vehicles driven by a linear motor.

This is one of a series of 16mm colour films made for schools. They were all made in Eric Laithwaite's "Heavy Electrical Laboratory" in the Electrical Engineering Department at Imperial College London.

Professor Eric Laithwaite: Motors Big and Small - 1971

This is one of several films made at Imperial College London in conjunction with ICI. The entire film, except for a short end sequence, was shot in the laboratory of Professor Eric Laithwaite at Imperial College London. This is one of many examples demonstrating electromagnetic forces and in particular the linear induction motor for which Eric Laithwaite was famous. Many of what he called his 'toys' are seen, these are models that help demonstrate the concepts and forces of electromagnetic induction etc.

Professor Eric Laithwaite (1921-1997) of Imperial College London demonstrates some of the most difficult concepts in electricity &​ magnetism.

Here is an interesting historical look at the "Senior" (Amiga 2000 version) of the old Electronic Program Guide software which ran on most cable systems throughout America and Canada during the late 1980s and early 1990s. (The EPG Sr. software was later upgraded into Prevue Guide -- the split-screen version seen at https://www.youtube.com/watch?v=UtvPd9MSCvs -- which also ran on the Amiga 2000.)

This particular video demonstrates the EPG Sr. running in maintenance mode as a local cable company employee updated the local scrolling and ticker advertisements it displayed while running normally. At the end of this clip, the cable technician finishes his work and puts the software back into normal listings mode. But apparently while getting up to leave, he bumped the Amiga's keyboard the wrong way and tossed the EPG back into maintenance mode without noticing. And that's how it stayed for the rest of the day.

The audio in this clip is another historical item in its own right: Cable Radio Network, which many cable companies used during the 1980s and 1990s as a soundtrack for their assorted computer-generated information channels.

Here's what the EPG Sr. looked like when running normally:

And what the EPG Jr. (Atari based) looked like, for comparison:

Electronic Program Guide in West Covina, CA on 12/20/89

The Weather Channel On Analog C Band Satellite 10-15-2010. The Weather Channel, the last major television network to utilize the VideoCipher II system, discontinued its analog signal on AMC 11 transponder 13 on June 26, 2014, effectively ending the VideoCipher era.
Occasionally, The Weather Channel would broadcast their feed unencrypted, sort of a free preview. That's likely what is seen here, as VideoCipher subscription service had been discontinued by this date.

Anyone who had a C-Band satellite from 1995 to 1998 should recognize this one -- the opening of "Basil Basset Bingo," a playalong satellite Bingo channel. The game was "hosted" by Basil Basset, a 3-D animated dog. Bingo cards were purchased directly from the station and activated to play and win at home. There were a few legal challenges to the game in some states (mainly Florida), but Basil himself was always interesting to watch. The station itself resided at S4-7, which a very weak satellite (as you can tell by all the static) and was a "holy grail" of sorts to get a perfect picture. More clips from Basil Basset Bingo (later 3BTV) is coming soon!

This gem from Lee's archive is from the first day he received the 4000. Earlier in the day before class he had the 3000, then while he was at school, two classes later, he passed through the TV studio to watch TWC for a few minutes. He noticed no narration during the a satellite LF broadcast, so he grabbed a tape and started recording. This clip was captured during that period. I would like to assume the issues displayed from the 4000 still initializing.

Promo for special New Years' Day showing of "Rocky" (first time on cable) then some computer-generated stuff listing other upcoming movies with elevator music til the next movie starts. (The music is still slightly audible under the movie when it starts- anyone know what music this is?)

Z Channel break- December 1977

This was between movies- in New Orleans where this was recorded I'm told it came in with a rented microwave antenna and receiver, but in San Francisco it was scrambled on broadcast channel 26 and you had to rent a descrambler to watch it.

Here we get some text with national news and a scroll at the top listing upcoming movies. Audio is from an FM station, WBYU (I hated these 'beautiful music' stations as they were called then, but now that they're extinct I miss them!)

At 17:18 you can hear the beginning of the station's hourly news with Dan Brown, then the next movie starts with a neat intro at 18:36 .

The song played before the news was recently marked as copyrighted- the entire video was muted until I told YouTube they could 'remove' the song instead- the audio in that part has now been replaced with the sound from the beginning of the clip! Glad the copyright holders of "Rainy Days and Mondays" have no issue with this!

Flipping through channels on Primestar on March 19, 1997. The videotape was damaged soon after it was recorded, so there are 2 splices in it. (00:22 and 02:40) This video is mostly me going into the service menus over and over again to find hidden channels which were being tested on Primestar's new satellite at the time. They were going to do a major channel lineup change on April 1, 1997. I sat on the Prevue Guide for a while, and that has been a separate video on my channel for a few years now. This video is the whole source tape from that night.
