How did you determine that this was the part to examine for failure, was it just from seeing other videos suggesting this is a high point of failure? Thanks for the videa and fix. Also noticed you are missing your anode cap as well, so people mentioning that it may have been rubber and disintegrated is up in the air now since I have seen quite a few without it. I found no residual parts inside my CRT when I opened it the first time.

Did this method fix yours? I found this fault by looking at the schematics and testing components with my meter. I think these early CRTs from RS just didn’t have caps on the anode.

@timothycolegrove4365 i hear ya, figured you poked around a bit before zeroing in on that one. Yes, mine does not have a cap but ordered a NOS cap and some grease, im suprised these sets dont show my visible or audible issues without it. Appreciate the reply, good luck, and keep the fixes coming, they are always helpful.

This makes for a truly invaluable piece of reference material as along with being an information dense review of the facility, it captures the mundanities of the space and time period that only a homestyle video like this could.

Until I saw this and another video recently, I never realized how profoundly slow these were! I didn't expect 5 MHz to be so much slower than Mac's 8 MHz, but it's clearly an OS difference. Even from a hard drive, it's dramatically slower than Macintosh from a floppy.

Thank you for posting it. The date I can tell is 1963 or later, as one of the movie titles shown at 8:20 in this video was released in Oct.1963. Another thing is that if the lady appeared at the biggining of this video is one of the families of USS Mansfield Navy Personnel, it will probably 1966 or later, as she was assined Yokosuka Naval Base a her homeport in June 1966 (per Wikipedia). Anyway, I am very glad to see this video, as it reminds me of my childhood in 60's.

@@timothycolegrove4365 Sorry for the wait. 0:15 Saikaya (Yokosuka's only department store) Christmas sale sign is up. Footage from 0:15 to 0:45 This is thought to have been taken at the intersection of the current Yokosuka Chuo Boulevard, "Joseph Hospital Entrance". (The location where it was taken is maps.app.goo.gl/GWzXUkaHCce3jkbn7) The footage from 0:49 to 2:50 is thought to be from Asahi Machi to Motomachi. The name has now changed to "Hon-chou". It is pronounced "Honchou", but US Navy personnel called it "Honch". This area was called "Dobuita-Street", and US military personnel used to drink alcohol and buy Japanese souvenirs. From 2:51, Yokosuka Chuo Boulevard and Mikasa-Dori Shopping Street are shown again. The bus in this footage is a private route bus called Keikyu Bus. 8:19 The movie signs "GYANGU-CHUUSHINGURA" and "JIROCHOU-SANGOKUSHI" are in the picture. These two movies were released in 1963. 10:04 Mikasa Catholic Church Is the "sign with the date" you are referring to the white sign in front of the church? If so, it says "Mikasa Catholic Church." The times below are the mass times. There is a Mikasa Church next to the Womble Gate at the current Yokosuka base, so I think it is that church. I don't know if the concrete wall shown in the scene where the woman is getting into the car is the same, but there is a wall that looks a little similar, but the Kanagawa Dental University next to the church has recently been rebuilt. There was also a port called "Ogawa Port" in this area. It has now been reclaimed and is lined with apartments, parking lots, and Kanagawa Dental University. Church location → maps.app.goo.gl/3nnZ7oXzrrwF5ch87 11:04 The long building on the right side of Yokosuka Central Boulevard is the Mikasa-dori Shopping Arcade. It was completed in 1959. 11:13 It is necessary to confirm whether it is the destroyer Mansfield (DD-728 Mansfield). I think the location of the photo is near Berth #9 in Yokosuka Base and the coast on the north side of the base. Judging from the situation of the streetscape, I think it was taken after 1959. If you add the information from the sign in the movie, it is 1963, and if you combine the information from the sign for the Christmas sale at Saikaya Department Store and the year-end sale (year-end sale) at Mikasa-dori Shopping Arcade, it is thought to be around November to December of 1963. This is my guess. I'm sorry I can't be definitive. I'm using Google Translate, so I'm not sure if the translation is accurate. The footage was taken more than 10 years before I was born, so I have no way of finding out any more. IMA, Tadafumi in Yokosuka

The tour focused on the "string test" that was to serve as a demonstration that the magnets and the project itself were on track and feasible. Unfortunately, it was too little, too late; the political die had been cast when the bore of the magnets was increased over a year earlier, significantly increasing the project costs and schedule at the absolute worst political time. It is difficult to say if the project would have survived in any case because of the loss of the Texan President and Speaker of the House. Many of the top engineers and scientists in physics research found themselves unemployed and forced to restart or change careers, a terrible loss for science and our country.

The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU.[2] Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics[3] and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines.[4][5] According to Harry Garland, the Altair 8800 was the product that catalyzed the microcomputer revolution of the 1970s.[6] It was the first commercially successful personal computer.[7] The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.[8][9] The Altair 8800 had no built-in screen or video output, so it would have to be connected to a serial terminal (such as a VT100-compatible terminal) to have any output. To connect it to a terminal a serial interface card had to be installed. Alternatively to using a terminal Altair could be programmed using its front-panel switches.

This is the best video I have seen of what it was like to use an Altair PC. I started using PCs with a Radio Shack TRS 3 in high school, and a COmmodore Vic-20 at home. But I never understood how to efficiently (for the day) use an Altair from just a few years earlier. The Altair was different to me because of the switches which made it look like something from the 1950s to me in the 1980s. NNow I can see how a terminal made it useful. I even had that same Panasonic Cassette recorder. Very cool!
