(For the 5 people who get this joke: psst we’re old)
mcSlibinas@calcifer imagine this: live so long to understand the joke and hearing the joke for the first time.
Oblomov@mcSlibinas @calcifer I wonder if there are greybeards who are old enough to get the joke, but don't get it because they never used DOS, only other operating systems.
M-A.Delsuc@oblomov @mcSlibinas @calcifer
I am !
never used DOS and barely Windows actually.
Even though, got my hand first on PDP-11 running RTX-11M (in 1978), got my personal ZX81 (in 1981!) were I wrote my first Fourier transform algo, Used RTX-11M, CP/M, Apple ][, Adakos (Bruker), VMS, CTSS (Cray), Unix (many flavors), Unice, Basic, Forth, Linux, MacOs 6 to 10, Android, e/os (in chronological order)... but no DOS ever.

I forgot one - the batch OS from the old IBM mainframe, with "control card" - what's its name... God I hated that one !
