I think it's worth mentioning that in France they had Minitel, a system run by the Postal Office that put a terminal in every household in the early 80s. What started as a way to save money by having the phonebook in a computer instead of printing millions of copies each year ended up becoming a proto-internet of sorts, with people sending emails and doing online shopping. It even had the same problems as the internet but 2 decades early, like a start-up bubble and controversy about pornography to minors

Funny that they were trying to do away with phonebooks all the way back then yet still in 2023 I receive a phonebook in the mail once a year. It just seems like such a waste to still do that. I'd guess around 99 percent of people who get them throw them straight in the trash or put them on a shelf where they will sit never to be used. As much as I like things from the past there is no reason to have phonebooks anymore. First of all the white pages are listings of people who still have standard land-line phones which is hardly anyone nowadays. And as for the yellow pages I can find the number of any business I want in a matter of seconds on google. I used to say they should still make them but only for people who call and specify that they want one. Nowadays though I think they should just stop making them entirely. How many people is the phonebook actually useful for? Even old people have cellphones now.

​@@kaktusgoreng What's interesting is that it was so successful that it actually slowed down the adoption of the Internet in France. These terminals were free and access was affordable (same price per minute as your average telephone call), so millions of households had one. They were also designed to basically last forever, since the technology was stagnant. When the Internet came along in the '90s, you had to buy an expensive PC for it (that would be outdated in a few years) and to many, it just didn't seem worth the hassle, given that all of the online services they were using were available anyway. Since Minitel allowed private firms to offer services for it however, these companies had no trouble transitioning to the Internet once it came along, given that they already had experience with online services.

As a sysadmin, I still use terminals; not only during regular operations with virtual terminals, but when a system is seemingly unresponsive, the hosting provider can provide a serial connection to the faulty server and this gets piped as-is into a terminal emulator through internet. Same for virtual machines; we can setup a virtual serial port for the guest system, and literally pipe that from the host to get a working shell from the kernel even though SSH and sometimes virtual display are broken. It's very useful, as it's very basic and does not requires much working parts.

What simply made it hard to use screens for text for a while was lack of good internal memory for the screens.

​@@leap123_ 24FPS has not necessarily been the standard since digital projection became ubiquitous. There are so many caveats and a lot of nuance, but it is film projection which actually was standardised at 24fps. Cameras had long since already had variable control over frame rate, and filmmakers commonly utilised that for artistic and practical purposes. An experienced camera operator could try to match the frame rate on the screen, but mechanical vs electrical limitations can and most probably will still end up being off.
@8bitwiz_
@8bitwiz_ Год назад
Early terminals often had to use delay line or shift-register memory, making them quite complicated. During most of the screen, you could only access the specific character being displayed, and that required lots of tricky timing to update the display. The time period where directly addressable memory became affordable, but a dedicated CPU was not yet affordable was rather narrow, and ended in the late '70s.

Even though I lived through this era (I’m 60) I never noticed that text on terminals started. It just seemed natural at the time. Maybe it’s because us software people saw it as going from punch cards to terminals and had seen the NASA stuff. The programmers of the 60’s & 70’s were so happy to ditch the cards and teletype style stuff they didn’t spend time thinking about what was really a huge evolutionary event in computing. Edit to say I’m not old enough to programmed professionally in 70’s was just in awe of the elders at work. I knew a guy that started working as a payroll programmer on an IBM System 3.

Terminal interfacing is still very much alive and relevant in modern IT. I’ve been a network engineer for ~27 years now. The vast majority of the equipment I work with every day still supports a physical serial connection to a terminal. Obviously this is almost always a terminal emulator these days, but a ‘dumb’ serial terminal would still work. When everything is at-least partially working properly, we can forego the serial connection and use IP (usually SSH) to emulate the serial connection over a network connection. But we always keep a serial connection handy for when lower level access is needed.
@szr8
@szr8 Год назад
Indeed. I've connected up and used serial interfaces on things like routers and IP cameras and other devices without network shell access, to rescue or gain access to the OS (often to enable ssh, telnet, ftp, tftp, etc.) Sometimes a serial connector header would have to be soldered in place first into the unpopulated points on the motherboard. It's amazing just how many devices are just mini/embedded Linux machines, much less powerful than a Raspberry PI yet still doing their things. Edit: typo

@soriac2357 Год назад
That was the case for the big, "wall type" screens, those were part video projection and part computer output. But the terminals seen at each mission control desk were something different, those were called "charactrons", video tubes which could display a fixed set of characters or even graphics. Each of these tubes were used with hardwired logic, that can change the display to a certain degree, obviously to display varying values, but also switching "pages" for different displays. But their function was pretty much "baked in", for whatever telemetry was needed for the controller, so you couldn't just, for example use the CAPCOM displays for FIDO...

Data displays were made in the 50’s and 60’s for military applications. Look up a Charachtertron. There was no digital pixel set to create as they used a physical mask to create the characters and they could write a whole screen of text with it. The founder of a company I used to do work for designed and built the first ones for the Convair corporation in the 50’s I believe.

Great nostalgic topic for me. As a home health nurse in the 1990s we had dummy terminals at our agency that were connected to a AS 400 IBM computer located in the hospital. We were sternly warned always to log off the terminals every time we used them for if the units were shutdown by flipping the power switch or if the power went out the whole system likely would crash. I was amazed at how well the whole system of 30 terminals worked. The terminals were spread out across town, connected by dedicated phone lines. We used the system for ordering supplies, basic word processing, for entering forms to be transferred to the US government for reimbursement. However, in those early days I accidentally typed in a global record delete that began to rapidly erase every patient in succession from “A” to “Z”. I could see the names flashing by on the terminal so I flipped the power switch which surprisingly interrupted the loop. Three temporary secretaries were hired to re type about 280 records up to the letter “R” which took several days to enter. I kept silent about my mistake!

You absolutely could write games for dumb terminals. When i was in college in the early 70s we had a PDP11 with 16 terminals. Most were Teletypes or Texas Instruments Silent 700s which used thermal paper and as their name implied were quiet. But we had a single Tektronics graphics terminal which used a storage tube. It used vector graphics not character generators so it was possible to draw on the screen. The other characteristic of the storage tube was that the entire tube had to be erased at once. Erasing flashed the screen. I wrote a fighter plane program called MIG 25 where you tried to shoot down a MIG. The erase function made a very nice explosion so if you hit the plane I'd erase the screen.

To riff on the end bit, the "terminal" software available in Linux and Mac has much more than a skin deep connection to this history. Its operating system architectures date from the period of true dumb terminals, with files like /dev/tty (standing for "teletype") to manage connections to user sessions, and it still supports the same escape sequences of characters that were used back in the day to move the cursor, change colors, etc. If you have one of these devices, you can most likely connect it to a modern Linux system (possibly with some work to enable insecure legacy stuff) and use it to log in and run programs just like 40+ years ago.

Indeed! This is a core component of why we can use computers without features like keyboards and displays, now known as "headless". One obscure bit of compatibility is for upper case only terminals like the one in Apple 1; logging in with an all upper case username tells getty to switch on case translation modes, as with "stty olcuc iuclc". Otherwise you couldn't type most Unix commands, as they are lower case.

It's trivial to enable, and not insecure! You get a login: prompt just like you do on a virtual console by pressing Ctrl+Alt+Fn, where you can choose F1 through F7. 7 virtual consoles are the default, and your graphical session (and graphical login screen, in some configurations) will use one. For all the others, you'll just see the virtual console number, hostname, and a friendly login prompt!

I'll be aging myself here. I went to high school in Utah and we were fortunate enough to have a two year program for computer science and programming. The majority of the systems we used were the still fairly new Radio Shack TRS-80 model 1 computers. We had one Commodore Pet as well which nobody used (I wish I had that now). In one corner of the room was a teletype machine. This connected to the Univac mainframe at the University of Utah and one could program in Basic, Cobol, and I think Fortran. Obviously it wasn't the most popular system to use, but I did do a few assignments on it just to try it out. Anyone with an account on the mainframe also had an e-mail address assigned. I never got an e-mail, though I wish I had because that mainframe was one of the original Arpanet nodes. So in theory, I could have gotten an actual e-mail Form a system in another state before there was an 'internet'.

Minor nerd quibble (the best kind in Star Trek); the computer occasionally shows text in the conference room when they look at people’s files, such as Harry Mudd or Kodos the Executioner’s criminal records. They also showed text on the bridge a couple times on those larger monitors near the ceilings. Such as Roger Korby or Gary Mitchell’s files. The wider point about the bridge, engineering etc almost entirely having graphs and status lights rather than text still stands though ;)

To me that is the sound of core memory when those old computers were running programs. Be it I was a little kid around those machines but that is what I remember and have always associated it with. I doubt anyone has any core memory systems that still work today so it's impossible to test if my ancient childhood memory is correct.

@petergathercole4565
@petergathercole4565 Год назад
And remember that IBM Mainframe (and other IBM compatible systems) used Bus and Tag cables to connect the disk and terminal controllers to the main CPU complex, These were thick and heavy cables that you wouldn't run overhead if you could avoid it. The sort-of rule of thumb was that if it was a data processing or computer machine room, the cables would go down under a raised floor (which also hid not just pipes for water-cooled systems, but also air ducts for air cooled systems), and if it was a telecommunication machine room (like a telephone exchange), the cables would go up to trays suspended from the roof, and the floor would be solid concrete (mechanical switching gear was heavy!). This has tended to break down over the last couple of decades, and now many computer rooms use overhead cables. This is mainly due to not needing individual cables per terminal (just network cables), and also the fact that often comms equipment like network and SAN switches are installed in the racks with the computers (so a lot of the cables are just restricted to inside individual racks), just needing trunks links between the racks. Also fibre-optic cables are often used, which are much lighter, and have much higher data bandwidth than older types of cables.
@ChristLink-Channel
@ChristLink-Channel Год назад
So true! My fist job was as a "Field Engineer" with Burroughs, installing miles of cables under the raised flooring. All kinds of cables down there, but the largest quantities were the hundreds of serial cables (full 25-conductor RS232 cables!) , running from the DTE boxes (don't recall the name, but each one could handle 32 lines, or later 64 lines) out to the racks of modems. And also the huge cables for interconnecting the mainframes to the printers, card readers, SPOs, and banks of disk packs, tape drives, and HPT disks. Those were the days! A favorite prank with those cables among the older field engineers was to send the newbie out the engineering storage area, for a "cable stretcher", when the cables weren't quite able to reach their destination... Yup, we sure did have a LOT of cables down there. An nothing at all "overhead", as some have suggested. The ceiling area in those data center machine rooms was all HVAC and fire suppression stuff. No cabling related to the mainframes.

It is wild how back then you really needed to know what you were doing to be able to use a computer. Technology moved so fast back then. You might go to college and learn all about how to use computers and in just a few years time all the information would be outdated. I'd say it wasn't until Windows 9x that your average person could use a computer without too much trouble. Windows 3.1 was a big step ahead but you still had to have a little knowledge of the system to really be able to use it. Once Windows XP came out then anyone and their grandma could use the computer pretty easily. It has been almost 22 years since XP came out and things really haven't changed that much compared to how it was back in the 80s and 90s.

I was happy to use the terminals if the computers were taken since it was all text-based anyway. I got an account on all the computer servers they offered, even though I didn't know anything about mainframe systems. I taught myself how to use Unix from the man pages.

As you can imagine if that silly 95 machine went down the whole store would grind to a halt until it rebooted.

The place I remember dumb terminals from most prominently (and fondly) growing up was in libraries that used them in addition to the old physical card catalogs. Especially if you were doing a term paper and needed to find out what articles were in periodicals about your topic. You'd look it up on the terminal, print the list of abstracts to the dot matrix line printer, then go through the list of brief abstracts or sometimes just titles and try to guess which ones were actually relevant to your term paper. Then you may have had to wait until your library borrowed the periodicals from another library to actually see and photocopy the articles. Does anyone know what kind of computer system in the library those dumb terminals would have been connected to?

The early terminals didn't use any RAM, they used wire delay lines -- a topic in its own right. A technology from the 50s and before.

It both bothers and amazes me how there isn't more videos on the history of terminals and older game genres. Like MUDs, MUSHs, terminals, ZZT (I've had a lot of weird Google searches recently, long story). They're all pivotal parts of computer and gaming history, but there's shockingly little documentation on them outside of forums, manuals, physical units in museums, and source codes.

I worked for Data-100 and supported the printers and card punches and card readers at Bendix Guidance, Bendix Flight and Bendix Aviation in Teterboro, NJ. This terminal equipment was connected to a mainframe in Southfield, MI. Teterboro was known as Bendix Borough for six years.'37 to '43.

In the 70's, I was a tech on a mainframe. All tranisiters, descrete and core memory 5Kb x 12 bits. They ran 2 branch and 4 other banks with online terminals. Crts, thermal printers and k/b. Altogether about 100 or so terminals. The ones in the main bank were running at 1200 baud, but all the out of town ones ran 300 baud. Even so we had a heck of a time keeping the out of town ones running. In those days RS-232 was not 3 wires and forget-about-it. We had to use the full RS-232 complement. If the telephone co moved our line to different pair (which they did a lot) we had restrap the serial port pcb for all delays and there were a ton of them. That is something people don't appreciate nowdays, exactly how hard it was to keep a remote RS-232 line running. Takes me back a year or two. Enjoy you channel.

Yes, to elaborate, even though David said a couple of times that the terminal and central computer would interact every time a key was pressed, that was not true of IBM mainframes. They were setup more efficiently. The user would type whatever keys he wanted. They would get echoed to the screen by the terminal itself. Eventually the user would press one of a handful of keys, usually Enter, but sometimes a PF key or a few others, and everything that had been typed would be sent to the central computer for processing, which would then send back data to refresh the screen as needed. Some mainframes had thousands of attached terminals and this really helped with turnaround time.

These were called "block" terminals (ex: IBM 3270).
@johndododoe1411
@johndododoe1411 Год назад
Oh yes, we used roomfuls of 3270-series terminals a lot in college, most were the basic 3278 with full keyboard (not the reduced cash register keyboard shown in some modern descriptions). There were also a tiny number of color or graphics models, but normal exercises were done with basic text models and knowing which seats in the converted auditorium could do bitmap graphics was important for the one class that would output graphs from the programming exercises . I didn't get within arms reach of an IBM mainframe until a later job when servicing a Compaq server in a business that had a modern one next to the server racks . The software was done in per login virtual machines with per student virtual discs and an interface using virtual punched cards . The machines were apparently on BITNET, but I never used that .

Interesting history lesson on how we got from teletypes to terminals. One thing to keep in mind is that PCs still run as terminals to this day, just smarter...not just the command line interface that you showed, but any time we talk to another machine over the internet, it's still basically the same thing. It's just that the protocol has become more sophisticated and more complex than 'just' the old ANSI codes. And then someone figured out how to send actual runnable pieces of code over the connection to be run locally instead of on the remote system.

Awesome showcase David & brings back a lot of memories repairing these for work & so cool to see Usagi!. Worked on ADM 11-32, Wyse 30-60, VTE 6 & 200 display terminals which were used on UNIX, PICK, some IBM 5364, some Control Data, CP/M & MP/M (multi user CP/M) in the late 1980s & was doing both field service at customer sites & also component level repair on both their logic boards & monitor sections, mostly through hole PCB construction along with both Genicom dot matrix & Dataproducts line printers. Sometimes we'd get oddball terminals for repair which were pure 74LS bit slice CPU logic, much like the PDP-11/40. Back then, those terminals didn't have a lot of the modern line isolation on their RS232 serial lines one normally sees these days with MOVs, transient suppressors etc & we'd dread any lightning activity as it usually used to kill both the 1488/1489 line driver ICs & if we were really unlucky it also killed the 74LS data buffer chips & much more. Supposedly, the RS232 length was max 50ft/15m but I'd worked with many sites who had 100ft/30m of RS232 underground cabling back to the central MP/M box via a few line driver plug in cards & even learned a lot of the hidden service codes. One time, we couldn't get the flybacks/LOPTs due to a transport strike & managed to successfully repair about 10 of them using a Dremel, fine soldering, HV silicone & special pre-mix black epoxy. In some sites we used 20mA current loop & one time at some industrial plants they had to use some specialised converter due to arcing from site machinery playing havoc with the 20mA signalling. Those dumb terminals were awesome to work on, nice construction, great support documentation & was sad to see them go. Back in the 1980s these things were everywhere until the IBM clones came out. Back then manufacturers really took pride in the things they created & quality PCBs too. It was hilarious when 56kbps BBS came out as we knew a lot of the ANSI codes backwards we had picked up from repairing these dumb terminals

As a little kid in 1987, my dad took me into the University where he worked and there were rooms full of ADM-3A terminals connecting to Prime servers. Even as late as 2001, my college had its library catalogue accessed through VT320 terminals (though soon replaced by a web-based system). Then at my first job in 2005, most employees had thin clients instead of proper PCs. These are essentially graphical dumb terminals - they send your keystrokes and mouse clicks to the server, and download bitmaps of the Windows desktop and whatever programs you are running on the server.
