I want to get a copy of Mountain Lion to put in Virtual PC, I went to app store, don't see it. Any ideas?

Just read and article that with Mojave which I just upgraded to two days ago, Apple, in it's great wisdom, has removed ability to get old OS. (wish I had known that week before upgrading, I probably had all old os in there)

I do see, thankfully installer, El Capitan, in my apps folder, only that one... but I wanted to try older ones: Snow Leopard to Yosemite. I think those work better with my old Dreamweaver CS3 I'll be using in Parallels.

Any idea how to get those old OS?

Apple wants $19.99 for 10.8.

YEs, sad Ira, but I found Yosemite an HIgh Sierra in my apps folder, so I should be good.

Ira PS

DARN IT.
OS X Yosemite
OS X Yosemite JUST says app store download and doubleclick take me to app store.

and this one more promising:

Install OS X El Capitan says application
But when double click it is says, "the copy is too old to be opened in this version.."

Wonder if it'll be ok in Parallels..

Wish I had more Installs, wonder why only El Capitan is in my apps folder and not other 10 from over years?
