    I remember refusing to buy a personal scanner for many years because we had a Linotype Saphir Ultra at Uni and the quality difference to anything a common mortal could afford was ridiculous. Our pool workstations had no floppy drives and their ports were pretty locked down, plus you couldn't install userland drivers back then anyway, so the scanner only made sense for student projects, right? Almost. With the Zip Drive, we noticed that apparently someone had forgotten to lock down the SCSI port, and Zip disks would just automount, world-writable. Any user could hook up their Zip Drive, format the disk to whatever they used at home, and copy away. This opened a niche for a select few nerds in the know who would proceed to lug their Zip Drives to Uni to copy off scanned images (and downloads, but who's counting). Since there were rather few of us, the ops never saw a need to shut us down, allowing us to have scans that still seek their match today.

    This vid is a legit treasure trove of interesting after working in a smaller locally owned print shop for last decade. A sincere thank you sir. Still dialing in the best avenues for making color accurate duplications of original artwork into archival ink and laser prints per medium etc. It always blows my mind when someone comes in with a random af state notated relic archive .tiff of some legit old as fk artwork/photography and it stands the literal test of time to the point it challenges modern views on format vs function, file size vs clarity. A bridge well worth the effort crossing though either from higher end clients doing large format limited runs down to aspiring artists looking for lower cost laser runs of post cards/stickets to slang at art shows etc for their rec marijuana funds, guns, ammo, etc. Cheers from Helena Design + Print in Montana, USA 🇺🇲🤘🖨

    I was sitting here watching this video trying to remember the name of my first scanner from the mid-90s. Then at @1:32:40 it popped up. I had the Mustek Paragon 1200. Although I (or more accurately, my parents) absolutely didn't pay $2000 for it, so I'm guessing I must have picked it up at the end of its life, or something. And although it was painfully slow, I don't recall its output being muddy/washed out. (Although I had nothing to compare it to)

    CRD, Microsoft might have placed a restriction on re-using the board and wouldn't allow the DVD drive use in an effort to strip the system of its game-playing capabilities, this seems to be the obvious choice by MS if they wanted a restriction because as you mentioned, the drive was used to verify the legitimacy of the console. The fans are likely for the power supply more than anything, that thing gets pretty damn hot on its own and being inside that case not only would make it run hotter, but it would also heat up the rest of the console.

    High resolution drum scanners. Hell - Linotype is one manufacturer. You had to know what you were doing. You mounted the photo or negative on a clear cylinder and it was then scanned by spinning it past an image sensor. No PC involved, everything was proprietary. You set up the scan by what you might think of as an audio mixing board arrangement of stacked knobs that represented each color and had adjustments stacked for like intensity, hue, saturation and contrast for each color ( Usually CMYK, but I seem to remember there were also selections for extended color gamuts utilizing oranges and greens as well. Worked well enough for outputting film both for halftone or continuous tone for Rotogravure plates. Extremely high quality output for things like expensive color catalogs, art books and pretty much everything else. A close friend ran one of these machines and I got to see it in use on a number of occasions.This was in the late 1980s -early 1990s.

    Mouse Systems is the reason I can only put up with the better, more modern versions of Logitech mice and no others. Mouse Systems ProAgio mouse was the first consumer scroll mouse, and its scroll was smooth. The later and much more popular Microsoft mouse had ratchet scroll. Modern Logitech mice (I use an MXMaster 3) were one of the few to bring back smooth scroll - with a mode toggle switch so you can also change it to ratchet scroll. Both are incredibly desirable in different situations, so it's the best of both worlds.

    I just realized as I watched this recently with a friend to show him some of the odd-ball video tape formats, it took multi-function machines to make my mother finally change over to a DVD player. I had bought a Sony PlayStation 2 six months after release (around April of 2001, I was a teenager still), along with a really nice bookshelf stereo for sound, and Metal Gear Solid 2 as my first game. I got that all hooked up, and then went to rent a few movies on DVD before she got home from work that day. I was busy playing Metal Gear, and she was stunned (as was I) at how good the game looked and that I had everything hooked up in the living room for the moment. Then I played a movie and she was stunned that my game console could do that. Well, a few months later, the first DVD player I bought her was a VCR/DVD combo unit, as her VCR had died and she was looking at just getting another cheap one to replace it. Ironically, it was years down the road that the DVD side of that died and I got her a really nice, high end DVD player used. I should also add that I gave her my Sony PlayStation, my Final Fantasy 7, and got her another RPG as well. I kept the rest of my PlayStation games, and she did not understand why till I shower her I could play them on the PS2 as well. 23 years later, and I still miss that console.

    That there are no pixel sensors which measure the wavelength of the light for each pixel is not entirely right. The Medipix collaboration at CERN has developed multiple readout chips for pixel detectors which measure the energy and arrival time of every single photon. Depending on what pixel detector you attach this could also detect visible light. It is used for X-Ray and particle detection and has a too low resolution to be viable as a camera sensor.

    ca. 58:20....ordinary fluoscend tubes are operated with AC and that wouldn´t be adequate for optical use. Because they would flicker and that would be bad for constant optical scan. So the power-supply for the fluorescend tube is powered with DC anyway? That would make sense. So thats the reason, why there is not a direct connection from 110v AC to the fluescend-controll-circuite. I do not know, how much voltage is neccessary to light up that tube. But it is maybe not as much, as it would be in normal use (with AC in our kitchen or whereever). It also did not have to light up big volume, just as the hole room, only that area between light-tube and the paper/picture, so...

It used a modified DVI connector called an ADC (Apple Diplay Connector) it was used with their flat screen monitors at the time (not their first (green/grey) one, that used VGA) It was sold with the quicksilver towers. I think it was 25v and VERY proprietary. of course, you could run one of these monitors off of a standard DVI port.... with a $150 (lol) DVI to ADC adapter.

    17:33 QQ is still a thing (that probably won't go away) which is a popular im software in China made be Tencent. And yes, the same company made WeChat because office politics or something... And I doubt any third party client of QQ would still work. Those originally would probably imitate a real client because old internet doesn't care about encryption, then it probably runs WebQQ in background. Neither would still work nowadays I think. And Tencent is known to be not happy about third party clients because those can have bot features, so much so they sometimes sue the developers to jail. Some say they do it to sell their own bot service but third party bots are often used to spam ads or porn (which when used with auto report bot can shut down group chats without the group owner being able to file dispute, called "exploding a group"). And for that, it's mostly better that they straight up don't allow third party client.

    First, scanners connected to the parallel port, then to SCSI, then directly to the main bus with custom cards, and finally to USB. And they worked just as bad with each interface, which at least tells us something: The interface was never the problem. Oh, and if you could connect a scanner to your parallel port was also a gamble, as the original parallel port was only designed to be an outgoing port (computer -> peripheral). But specification aside, many parallel ports could actually be used both ways from the beginning. This was neither a bug nor a feature, it was just due to the simplicity of how these ports were built and the fact that you had to artificially prevent data transfer in the other direction, but why would you do that? It would have just cost more money for no real benefit. But as the video said, this port was very slow; 50 to 150 kByte/s. As you can see, it didn't even have a designed bus speed, as the speed depended on many different things and thus would also fluctuate a lot whenever you sent data over it. It was basically: CPU writes a byte of data, then signals that data is on the bus, finally the device signals that it has read the byte and then the whole process repeats. The CPU, the device or how the port was connected to the bus all would influence data transfer speed; even cable length did matter (the longer the cable, the more latency; and even if latency is tiny, keep in mind that's latency per byte and it will sum up). EPP (Enhanced Parallel Port) officially supported two-way communication (it was a design feature of this port) and allowed up to 2 MByte/s. ECP (Extended Capabilities Port) allowed data compression on the bus (up to 64:1 was theoretically possible, realistic numbers were closer to 4:1), and the bus had a 16 kByte FIFO buffer, which allowed even faster transfer because the CPU could now read/write data in large chunks instead of byte by byte (also, data transfers would take much less CPU time overall). Because the ports all looked the same, most people didn't even know what kind of port their PC really had, and a printer would often work on all variations of that port (just at different speeds), because it was possible to detect the port's mode of operation in the software for both the driver and the device, just by looking at the signal lines during a data transmission (the signal lines were not used the same way in different modes, which made it possible to detect the mode). A scanner would normally require at least EPP, because as I said, only EPP guaranteed two-way communication, and even if the scanner could work with SPP (Standard Parallel Port), it would have been awfully slow.

    I kept my old analog tv as long as possible and had netflix with mail in discs. June 2009 they finally cut broadcast to analog tv so I got a 720p TV with a ROKU and used the plex app to steam movies from my desktop over the network to the TV. I never realized people put actual computers under their TV.
