I'm an idiot!!!

Didn't even think about Build (Version) Numbers!
On the subject of OS Builds;
Last Night, as my Wife and I were searching for some Christmas Decorations that have been on the "M.I.A." list for > 10 years, I "uncovered" some older IBM Tech manuals, which have been in storage for so long I forgot they existed!
Within this archive of IBM docs were a couple of the basic "Introductory Manuals" distributed with a new Workstation.
These Manuals are entitled:
"IBM PC DOS, Microsoft Windows Second Edition; User's Guide"
Of course, my part of the search for the possibly irretrievable Holiday Garnishments has now ended ...
PC DOS 7.0, and Windows 3.11 are covered.
Remember Program Manager and File Manager? It's been years since I last saw those Windows - let alone the basic setup of a "Pre- Win 95" Window or Icon!
As to the other IBM manuals, found an old Maintenance Library Parts Catalog for the 4701 Controller (dealt with these on Bank Branches), a 3270 Connection Quick Reference Manual, documentation for Token Ring Concentrators (MSAUs) - connections via Type 1, 2, 6, 8 & 9 STP Cabling (illustrations depict Type 1 Cabling), and a Token Ring NIC (Network PC Adapter) Hardware "Guide to Operations", relevant to installs on IBM PS/2, Model 25 & Model 30.
The "Guide to Operations" included Drivers for the 16/4 Adapter on a 5.25" Floppy (not old enough to be on 8" Floppy, but not young enough for 3.5" Floppy).
I do not remember how to identify a High Density 5.25" Floppy -vs_ a Low Density version. It has really been a long time!
Anyhow, just wanted to mention this.
BTW, the Decorations are still an active issue, of which I was promoted to head up the search for the absent items as a committee of One!
Figuring if I run across any more boxes of archived cool stuff, we should have the Christmas Decorations by July 4th, 2025!
