Yabbut, in the early 90's I used a DOS multitasker that let me switch on
the fly between OrCad, Word and other stuff.
That's not multitasking, that's just swapping one app out for another.

No, there were true multitaskers such as Desqview available; by "switching" he
just means from "screen" to "screen," since there wasn't a regular
GUI/windowing system.

Absolutely not. That was a task switcher... period. While one task
was active, ALL other tasks were frozen. THAT is SWITCHING.

I has something that ran as a TSR in real mode DOS and let me
multitask a few applications (like a download and a text editor and a
command line) it was shareware

You do not understand what the meaning of "multi-task" means.

I could have TEN "tasks" "up" under DesqView, and ONLY the ONE task that
was in the forefront was actively getting process time.

Then, in that respect DesqView was inferior to the prog I had,
Desqview386 did allow you to assign a certain amount of processor time
to background tasks.


That is the same for your TSR.

No. it was multitasking, the background task was transmitting and
receiving data, reading and writing files, etc... If I didn't tell
it to use BIOS calls for its display output it'd crap all over the
display of the foreground task.
Yep, and some didn't understand that even BIOS calls could mess up
graphic screens.

it was a nasty hack that had other disadvantages (like having to
partition the 640K into chunks for each application) but it did do
multitasking.

There were no TRUE multi-taskers under DOS. That's not only a fact,
it was a rule.

You're misinformed.
Hair splitting.
There may have been task dispatchers and pre emptive systems, but unless
the CPU had multiple execution units, there was not TRUE multitasking.
Just the appearance to us slow humans.


DesqViewX was the first and only exception as it supplied a gui interface, that gave timeslices to all active apps
running in it. Even Windows' early releases that ran under DOS didn't do
that.

yeah until 3.x's 386 enhanced mode there was no dos multitasking in
windows.

I still have a copy of DV/X.
I loaded it up on a machine not too long ago and it REALLY sings on new
multi GHz hardware!
