> it's quite a feat to fit this into 4 MB on a 386.
I had 2 different Librex 386SX laptops, with 4MB of RAM, on long-term loan from work around 1992. One was quite chunky, the 2nd was a slimline thing with an off-centre hinge.
I ran OS/2 2.0 on them both.
So I could run multiple DOS apps, and a WinOS2 VM containing Windows 3.0, meaning I could run Win16 apps as well. And native OS/2 apps, although I didn't have many.
A 386 with 4MB is small now but at the time this was a fairly serious workstation-level PC. At the time my work desktop was a 386DX but it had only 1MB of RAM.
In its time a 4MB 386 could run any one of multiple multitasking 32-bit protected-mode OSes, including OS/2 2.x, SCO Xenix, Coherent 3 or 4, DR Concurrent DOS/386, and so on.
This was a high-end bit of kit and with one of these OSes, or even with Quarterdeck DESQview, it could multitask half a dozen large and demanding DOS apps, or maybe a couple of the still fairly new Windows apps such as WinWord 1, or Excel 2.

Here's a pic of the original Librex:
