- 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!!
Well done Keith. Very interesting information
Thank you!

If I'm not mistaken FreeDOS is released under the GPL license not public domain
Thank you very much ❤️.
You helped ease my presentation.
I really appreciate
Very informative , whole lotta thanks for the post tbh
Nice video, you seem to be real guru in computers
Very good video brother
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.😊
cp/m command prompt monitor
LOL this looks Shade...
That looks Vaguely Familiar from the early 2k's
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
Thank you! Will definitely watch!
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.
sequel to MS-UNO
Nope - they used the Skip card on that.
un, dos tres
3 bit CPU?
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.
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
DOSBox is not an operating system ....
war games was unix not dos
I believe WarGames was using CP/M, as he was running on an IMSAI 8080.
You could get the same experience using a Linux server lol.
