  • Remember DOS? If you don't, learn about how a family of operating systems produced the giant which was MS-DOS, eventually leading to Windows, and how other DOS variants were used on every computer imaginable. If you do remember DOS, take a trip down memory lane and revisit computers in a simpler time.

    Wow, great video! My childhood just came back to me! Amazing how much of windows in born out of DOS... I always felt weird using DOS because I learned computers on CP/M... Crazy!!

    If I'm not mistaken FreeDOS is released under the GPL license not public domain

    heheh I still remeber a few .bat files I had on my PC, depends what I want do. Memory with XMS and drivers in 384k for gaming. and EMS for daily office job :)
    Eh, old good days with Norton Commander, Lotus123, Framework :)

    On touch screen the mouse driver let me get the x,y- coordinates. But i am not sure how left/right click works without a mouse.😂

    I still use Microsoft Word for DOS ver 5.0, as I'm still running XP

    Today we can still run old DOS programs and games on a free software, DOSBOX 1.0, a virtual DOS emulator. I still play "Wolfenstein" and other old DOS games on my Windows 10 operating system.

      I am on an Android tablet with a not official DosBox app installed to create tiny executable files and some videos(no speech) to show how it works in DosBox. Have fun.😊

    Nice video.
    If you understand Italian, on my channel I made 4 videos where I talk about DOS memory management, and why it was so hard to go beyond 640k of RAM

      We can access the linear framebuffer of a VBE video mode(in the 4th gb example in C0000000) from DOS if we switch into the (not docemented) 16 bit BIG Real Mode of the 80386+ CPU and open 21 address line with a segment size of 4 gb for Segment DS,DS,FS,GS and 64 kb for CS and SS Segment. The latest himem.sys XMS driver use it too. I used some Intel and some AMD and all of them let me do this. Last Intel core2quad 64 bit CPU with Radeon 9750 PCIe booting from 2 gb USB-stick or self made boot CD-ROM MS DOS 6.22.

    where did you get that war games was using DOS? "The IMSAI (used in War Games) is largely regarded as the first "clone" microcomputer. The IMSAI machine ran a highly modified version of the CP/M operating system." Yeah this is not the dos you are looking for.

    Where's echo off? Worth giving MS-DOS 7.10 a try, regardless, not putting DOS in a good light in this video. You should've showcased all the DOS features making DOS what it is.

    4:36 We would watch videos on computers and phones today even without MS-DOS (or Microsoft's) existence.

    640 k is 5 and a quarter million d flip flops. People are just greedy.

    • @herrbonk3635
      @herrbonk3635 Рік тому

      It was usually dynamic RAM "DRAM", so no real flipflops for the memory itself only a lot of addressable transistors paired with a capacitance. But yes, 640K is 5 242 880 bits, so it would have been that many latches using static RAM (which a few handheld PCs actually used).

      640k was a flop

      I believe WarGames was using CP/M, as he was running on an IMSAI 8080.
