I was really curious to find the sources of the files from this zip, https://www.mediafire.com/file/mm7cjztce9efj4w/8086.zip/file This zip file is mentioned in every website and video tutorial for setting up MASM using DosBox, but yet there's no mention of where they are from or what they do. These files are collected from older operating systems, so for the most part, direct downloads for these files do not exist.

The following information is gathered from the links above
Runs on and produces code for 16 or 32-bit x86 MS-DOS, released in 1989
The earliest versions of MASM dates back to 1981
MS-DOS versions up to 4.x included Microsoft's LINK utility
Included in MS/DOS versions 1 thru 3.1
Part of DOS 1.00 and has been included in MS-DOS
Originally named DEBUG.COM, the executable was renamed into DEBUG.EXE with DOS 5.0
Version 1.0 appeared in MS-DOS 5.00
August 11, 1999
Because this requires a 8.3 naming convention and was released in 1999 we can assume this program was created with Windows 95 or 98
