I want to add it was owned by two universities before I got it so I might think about reaching out to one of them, probably the original university since the one a actually got it from in my hometown didn't have any disks for it.

Hope someone has a more immediate solution, but I will have to remember you if I happen to get into the inaccessible storage where my 5.25s are in a few months
FOR few= 3 TO 40
Because I remember having some early compaq disks, might have been for portable, might have been for deskpro 286, it will be a surprise. Last seen over 2 decades ago which is why I am not super sure/precise.

There is some Compaq Diagnostics programs here, years ranging from 1986 onward, however they are targeted at the Deskpro 386.

Compaq MS-DOS Dos 1.11 (1982)

386 is way too new and that DOS version is too old that system was released June 28th, 1984. So, if anybody has a disk from later than that time and not from the 286-386 era. That's the kind of disk I need.

For anyone also wondering with their Compaq 8086 here's a link I found:

Ok good news, I got it to the point where needing that disk is not priority. That system that I found was a little broken so i'm doing some repairs. The original CRT that came with it (monochrome green) and then the keyboard are both not working correctly, thankfully I already fixed the floppy drive.
