YouTube, and interesting technology favorites

This time, I’m not going to talk about a project or an “old equipment concept”, but would like to introduce some interesting users or their contributions from the YouTube portal. These are contributions from the field of computer, technology and science, which I personally like to look at.

First and foremost, I would like to mention the legend of modern computer history, which has fascinated me since my youth. The ComputerClub from WDR times with Wolfgang Rudolph and Wolfgang Back. The two moderators moderated the program Computerclub from the beginning of the 80’s to 2003 at Westdeutscher Rundfunk. In the topics, the two men are generally concerned with computers and peripherals, new developments in the field of electronics and present all sorts of things here. Many broadcast recordings are archived on YouTube, including by user janbras.

On 22 February 2003, the last broadcast was broadcast on WDR.

But the two protagonists have not given up the computer club and let him resurrect on July 24, 2007 on a German private broadcaster (NRW-TV).

However, the private broadcaster NRW-TV had to cease its operation in 2016 and so the program was Nr.186 recorded as the last in the studios of NRW.

But Wolfgang Rudolph has managed by fundraising to set up his own studio and now produces the CC2 from his private studio on his own.

In the background, a lot has changed, which confused the viewers and freaks a bit. Parallel to the broadcasts existed the page cczwei.de which was filled by both gentlemen. After 13.12.2016 suddenly a new page appeared. The new domain cc2.tv has been created. The now operates Rudolph alone. The domain cczwei.de continues to be operated by Mr. Back. He is assisted by Heinz Schmitz, who is now producing YouTube broadcasts with Mr. Back. Apparently, there were sufficient reasons for the gentlemen to part with years of community work. There never was an official explanation.

 

From the computer area, the guys from VirtualDimension report. They call their channel VD Hurrican and produce the formats: Virtual Worlds, Back in Time, Retroplay and On Site. The contributions are absolutely professional and mainly deal with home computers. With a lot of background information the old 8 and 16 Bit’er are presented here. Gameplay as well as fair reports and contributions from community events are also part of their repertoire. As an example here a link to the unboxing of an Amiga500 and its history. On the occasion of their 1000th subscriber on YouTube, they have published a 1000-subscriber special with a studio tour.

From the Australian continent, Dave Jones, also an inveterate technician, blogs. On his YouTube channel EEVblog, He also introduces electronic devices, explains their structure and operation. A special category in his channel are the so-called Mailbags. Here, Dave receives packages from people in the community who he opens in front of the camera and presents their content. This can be old computers and boards, or even new developments and prototypes of startups that are presented here.

 

A slightly different channel is that of an Englishman. He calls himself Photonicinduction and shows experiments with high performances. All sorts of appliances, such as vacuum cleaners, heating lamps, washing machines, loudspeakers, etc. are operated to the limit of their maximum performance data – and far beyond. The end of the device through destruction is the goal here.

2.5 inches earlier and today

Before it lands in the archive, I have to put it here too …
It is a hard drive from the 90s (exactly 21.10.1991) – namely a 2.5 inch disk from Seagate with the incredible storage capacity of 85.3 MB (yes MEGABYTE). In comparison, a 160 GB (Gigabyte) disk from Fujitsu in 2007.

The Seagate disc with the designation ST-9096 was installed in a Commodore Amiga 1200. It kept the complete Amiga OS 3.1 including plenty of applications space. At that time you could not get that 85MB so easy.
To the technical data: If you want to format it today, you should know the following parameters: 980 cyl, 10 heads, 17 sectors gives a capacity of 85,299,200 bytes. The HDD has a power consumption of 2W in read / write mode and 1W in idlemode. 300mW still consumes it in sleep mode.
Interesting is perhaps even the size comparison to current records.
 
The interface complies with the IDE standard (Integrated Drive Electronics).
