PC's can run either open source or closed source
OS's.
Does Acrobat run under any of the open-source ones? Is Acrobat itself
free (at least as-in-beer)? And I'm still not about to sink my own
time into the rathole of sysadminning the machine, not with
closed-source software on it (even if the OS is open).
I don't know of any classic computer that came out
with open source
DOS's (but a few open source monitors).
...so? None of my machines, classic or not, run the OS they came with
(if any); I'm here for the hardware, not the software, side of things.
(When I have the OS, I have a copy of it archived, but I don't do
anything with them; they're against the day when I do find a reason to,
or for a putative someone else.)
