Yet another case where text printed on paper outlived any digital storage.

I wonder how long it'll be before they release the source for the earliest Windows versions. The fact that they still have the source for this very old DOS at least gives hope that they also do for old Windows.

I am sure that there is a lot good material to take inspiration and learning even from the early Windows 3.11.

Do a deep dive into how OS/360 formalized to having DOS.

Seems like it was never digitally stored in the first place, and the printed text was barely readable due to age. Not really a big win for paper.

Well it had to have been on disk or tape at some point. It wasn't all typed in by hand every time they needed to build a new version.

It sounds like this printout has deteriorated badly and was barely readable.

They waited a couple decades too long for this to be of interest.

It is wonderful how early years of modern computing was brilliant. We treated machines as they really are: machines. Performance, creativity, science..., all possible to make a 386 machine work. Nowadays is all about libraries, virtualization, [bad] code over [bad] code over [bad] code..., I dont like it.

I sometimes think that my mental model of a computer is still an Apple ][+ with 48K of RAM leads to my writing better code.
