Funny you mention this, when the DOS Extended vs. Expanded RAM confusion and product battles were occurring in the late 80's it made me think of the 41 main vs. eXtended RAM confusion in the early 80s!

Indeed, I remember that - at the time - I thought that I already went thru all of that! ;)

Sure!
And I remember how much expensive were all those RAM cards.

Ditto!
And I stayed with the dynamic duo QEMM + DV386 up to 1996, when Windows 95, not running under DV, forced me to embrace the Win world.
