    DOS is a nifty operating system. I credit the fact that I know as much about computing as I do to the fact that I had old computers to play with and experiment with in my formative years. DOS is simple enough that you can basically learn the whole thing in a week or so, but versatile enough to still be useful. Giving a curious young mind the power to know how a complex system works inside and out is a recipe for self education. Unfortunately, today's most common modern computing devices aren't so transparent. With so much of the inner working buried in countless layers of abstraction, they may as well work with magic. You can't play around and see how it works. It's depriving a generation of something great.

    My favorite thing about DOS is its ability to run in extremely limited environments. And although newer systems added more and more resources (faster CPUs, much more RAM, storage etc), modern OSes have placed so many additional demands on the system that it doesn't _feel_ as fast as DOS was back in the day.

    WordStar on MS-DOS (on my dad's Compaq) was the program that made me fall back in love with writing as a teenager. I've used many other word processors since then, but there was just something about it that made me want to write.
    The funky way its default view had a command menu covering half the screen seems absurd in hindsight, but it had the effect of making the program seem trivial to use. Everything you needed to know was right there (unless you hid the menu, which you could).

    Don't forget that CP/M had a GUI too, called GEM, graphical environment manager. It shipped at standard with some systems, notably the Amstrad PC1512/1640 in the UK in the mid to late 19800s. I've done a fair bit of programming in the companion product, PL/M, programming language for microprocessors, which was Intel''s standard supported language on its development systems alongside ASM/xx an assembler.

    • @eekee6034
      @eekee6034 Год назад +3

      Curious, I thought GEM was first developed for DR-DOS. After a bit of searching, I see DR DOS was a CP/M-86 implementation and MS-DOS compatible, interesting! Still, I don't like GEM very much. In Atari ST form it was my first GUI operating system, and I refreshed my memory of it in recent years with OpenGEM under FreeDOS. In neither case did I find it comfortable to use. The version in Atari's TOS 1.4 ROMs (or was it 1.04,) was improved; you could scroll without losing your selection, but OpenGEM lacks that improvement. OpenGEM does have the improvement of menus only opening on click if you wish. (I think TOS 1.4 had that too, but it was too long ago.) On the ST, the combination of a terrible mouse with my neurological problems meant menus were always jumping into my view! lol But both my health and mouse technology has improved tremendously over the years.

I did fire it up out of curiosity and remember looking at some appointments or calendar app but that was about it. It may have also included GEM Paint, not sure. There's a video "The Amstrad PC 1512 Computer with Tom Scott" here on RUclips. At 15:37 you can see the GEM desktop. This was back in 1986, only a couple of years after the Mac launched, but Apple made sure to make more of a thing about the OS. It was a bit slow too but that could be improved a bit by fitting an NEC V30 CPU instead of the 8086 (it had the genuine 16 bit CPU).

      I still miss the fact that you could set it to beep on a spelling mistake, rather than having to go back and look for highlighting or wiggly underlines and the other visual indicator everyone else used.

    Man, it's hard to believe that all this DOS stuff is really ancient history, and little known by most people. My first PC compatible computer was a Packard-Bell 486 in 1994. So I actually missed most of the earlier DOS development, as my computer had MS-DOS 6.0 (which I quickly upgraded to 6.22 and ran Windows For Workgroups 3.11 on top of it. I loved WFW, but I certainly explored everything I could find on the computer, including all the DOS commands and programs.
    Later on, I played wtih OpenDOS/DR-DOS which had some nifty features to it as well.

I have to point out however that many of the DOS 2.x commands were unbelievably braindead. The "more" command being a prime example. In the early 80's I was exposed to Unix and found its "more" command so superior to the DOS version I wrote my own DOS version in assembly so that searching and paging backwards (as well as forwards) worked.

    4:20 keep in mind the "Operating system" was a completely separate to whatever allowed you to control/manage a disk drives. Depending on how you booted the computer, it may not be able to access a disk drive, if the drive was powered on AFTER the computer booted, it would be unaware of that peripheral, and you had to reboot again to load data from a drive.
    Atari 8bit computers were like that, which allowed it to have more RAM free if there was no disk operating system loaded, but it also allowed it use various kinds of DOSes to fit your needs. You could run simple boot-loader menus, that booted FAST and only used a TINY amount of space on the disk to boot, display it's contents and wait for the user to pick something from a menu. Then you had more traditional Atari DOS menu driven allowing you to manage files, but you had to exit out of BASIC to use DOS, and vice versa to just get a directory listing. Then there were command line DOS like SpartaDOS which was very similar to MS-DOS that allowed batch files to run.
    Yet other computers like Commodores didn't care what powered on first and let you "boot" a floppy disk with a simple command in BASIC, meaning it's "DOS" was always loaded in RAM, even you didn't own a floppy drive. Yet to get a directory listing meant you had to clear whatever BASIC code you had in memory since the directory listing was loaded into memory as a BASIC program, as REM statements. So you were stuck with just one way of interacting with floppy drives, at least until Fast Load carts came into being.
    These days the OS and disk management is all under one roof now.

    If I remember right DOS 4x is when they added much of the myriad of batch commands - which are now considered "magic" commands - How did you do that in a batch program? (I wave my hands) - magic!!!
    These are commands you now have to look up on stack overflow these days. Things like picking out text in file.... you can do that in a batch?????? Yes, yes you can.
    I was once told at work that our database program array was too difficult to automate. Our programmers tried and tried but they could not get away from the manual intensive methods of installing a program and then setting it up manually, over about 5 programs that dealt with the database. So I wrote a batch file that did it because I was doing testing on an array of customer database mockups and I identified this manual BS as the biggest time waster. I took a 3 hour process and made it a bit less than 10 minutes. Our programming team could not figure out this batch file, and I had made it with functions and well thought out routines. This was NO spaghetti code!! It was properly structured with error traps and all the bells and whistles a regular program has... about 1900 lines of batch code. Eventually I had to write a white paper on it, as to how it worked because it used such obscure batch commands, no one could figure it out!!! Actually, there was some code in there that I lifted from stack exchange, and I wasn't even sure how it worked, but I knew what it did. Needless to say,, our programmers were none too happy that an engineer did what they said was impossible.
    Thanks stack exchange!!! couldn't have done it without you!!!!

    • @chaos.corner

      Definitely the way to do it. We had two scripts, one to create the database and one to update to current. When you wanted to modify the database, you'd never modify it directly but would add the code to the update script and run it. At various intervals, you'd make a new create script and empty out the update script (or just keep it).

    From my perspective, DOS was an exercise in forgetting everything that anybody else had learned and making their own mistakes all over again.
    I had been working with PDP-11s (RT-11 and RSX-11) and a VAX 780. I was used to multiple people sharing a machine, and running real-time multi-processing.
    Then DOS came along and forgot all that. Then it added kludge on kludge (extended memory paging/swapping) and weak forms of multi-processing. As an engineer used to reliable, predictable multi-processing, this came as a rude shock when I was forced to write software for Windows 3.1 to drive analytical instruments.
    It's not because DOS works with less resources - our PDP-11s had around 256KB of memory.
    OK, we're way past that now, and modern OSs (Linux and Windows) far exceed the capabilities of those early engineering OSs. But we could have been here quicker...

      Kildall did acknowledge the influence of various Digital operating systems, but mostly TOPS-10.

It's incredible to think of all the split energy inside that company trying to support so many systems. Luckily they had a hit with the superb VMS (which was heavy influence on Windows NT of course). Operating systems are a small world of people 'borrowing' other ideas.

    looks like the power on detection circuit is a bit iffy. In general from this era, they worked by pull the cpu's reset pin down (RESET) at power-on, for a few milliseconds. then, after the psu had stabilised, releasing it. My UK101(Ohio superboard 1978) has a reset Switch on the keyboard. You could do this, put a little spring loaded reset toggle switch on your unit. Or, look at what's connected to your cpu's RESET pin. There's only two possibilities for failure of power-on reset circuit. 1) it fails to pull RESET down (or up depending on which cpu) at power-on. 2)it isn't holding it down long enough for your psu to stabilise. This looks alot like case 1. If you follow the circuit from your cpu reset pin, a pc from this era, might have just a pull-up resistor to 5v, and a pull-down capacitor to GND. Check out the Capacitor first. You can buy, or I can send you, power-up reset detectors nowadays though. they're really cheap, and only about the size of a BC547 transistor. They were designed to get around the problems of dodgey power-up detection using R-C circuits.
    Also, if your psu has a lot of ripple, this can cause R-C detectors to act weird. Though, in the short clip you give at end, yours doesn't look to be acting up in the right way for that. That momentous fist sized electrolytic, should be 1st port of call if your scope shows psu is excessively ripely. As ever, AWESOME VIDEO, respect! please keep em coming, and show us this old veteran in action soon.

    • @gigatesla
      @gigatesla Год назад

      Definitely good to check on the electrolytics. If they're not sealed well then the electrolyte can leach out over time, which causes them to lose capacitance. I think there was a problem with Chinese capacitors manufactured during a certain time period that had this issue. The overall impact is that it will either pull down for a shorter period, or won't pull down at all, either way not giving the PSU enough time to stabilize.

    • @herrbonk3635
      @herrbonk3635 Год назад +1

Personally I use reset and brown-out detectors nowadays, they're so much cheaper than in the 80s. But your right of course, they also just pull the RESET pin down till PSU has stabilised. Just more reliably than the old RC ever could.

      Your mention of the UK101 brought back some memories of building mine somewhere around 1980, and the hours of keying in BASIC programs from computer magazines, and waiting for a cassette recorder to reach the correct place on the tape, before actually loading the code. Around that time, I was in charge of a 24 user unix system running purchased COBOL business programs for which I had negotiated getting the source code so that I could add features for job costing work done in a bespoke spring and pressing manufacturing company. I missed all the unix commands on my home computer, but some time later I heard of unix simulator - MKS Toolkit - software that would run unix commands under DOS, but could not afford its cost. I contacted the company selling the simulator - based near my home - to try to get a 'student' version, but ended up using my previous technical author experience to write an appraisal of the software for them, which was published in the April 1988 issue of a magazine called .EXE. Not only did I get a free copy of the software, but I also earned the unexpected sum of £317 for the 3,170 word article!

I'm fulfilling my life long dream now and learning MS-DOS, C and Assembly, and I'm working on a VirtualBox machine for now on my MacBook.

      The programs I wrote for myself on MS-DOS were pretty simple but helped me to get stuff done.
      For example, I didn't like certain DOS commands, so I made my own versions in C with new features, like a version of TYPE that converted text to upper/lower, converted tabs to spaces, etc. Or a version of DIR that colorized the output so it was easier to see what was there. Things like that.
      I also made small utility progams that did specific, useful things. As an undergrad physics student, I wrote a lot of programs in FORTRAN77 .. and I might write that in a local editor, and then dial into the university VAX to compile it and run it. So I had a program that did certain checks for FORTRAN77 (like a primitive linter, but targeted specifically for me). That way, I spent less time dialed into the modem pool for coding and debugging, so I could use that time to just run my stuff and hang up.
      When I started using LaTeX to write documents, I wrote a QBASIC program that prepped a plain text file for use in LaTeX. And when I started exploring nroff (see my other video) I wrote a program that converted my LaTeX files to nroff (if they didn't have equations).
      And I wrote one-off programs to do data analysis for my physics labs (a lot of those) and do numerical analysis and numerical simulation.
      These were not very sophisticated, just stuff that helped me do my thing.

    21:12 Oh yeah the reason they made it monochrome is because it was a design choice. The tradeoff was, have a monochrome desktop and have 512x342 resolution. THat makes it much more useable for desktop publishing and productivity software. Whereas the Amiga 1000/500 and Atari ST had color, but only 320x200 which is why GEM and Workbench looked like toys. That was the choice given only a certain amount of VRAM in the machine's budget.

    Hi, good video
    What about a video on DOS file managers (with split screen, and all other functions just, or not, included in W10/11) ?

      It's an older video (2yrs ago, so the quality isn't great) but you might like this video on the DOS Navigator file manager on FreeDOS. ruclips.net/video/N6Vyr52eiw4/видео.html

    Remember the program X-Tree Gold? That was my go to program for managing files and directories, it's a program like Total Commander which was very useful.

      X-tree was awesome. Did you ever try Z-tree?

    Started with DOS 5.0 on our 386 and eventually ended on DOS 6.2 before transitioning to Windows 95. Good times.

    I used PCWrite on DOS, did the job well enough and was shareware. Even bought copies of it for work, licensed.
    Also used Enable 4.5 and before. Fantastic office app with SS, editior, DB, & more. I think the DB is better than MSO or LibreOffice (which I use). Enable's DB could do amazing things, and on limited hardware.
    I still have the files to run PCWrite and Enable, but do not have the desire to go back to that hardware.

      A lot of great shareware from the DOS era!

    Can you run Foxpro 2.0 for DOS, the pre-Microsoft fully relational database?

      I haven't tried (I don't use it) but I imagine so. FreeDOS runs lots of DOS programs.
