Yes, if only we had unlimited funds and space!
I see the original IBM PC, the 5150, more a part of the earlier "era" where there were several companies vying for the computer buyers money, many of them in the CP/M arena, and some not. This is where I came in, using a North Star Advantage and Horizon.
From here I am only mentioning the Intel/x86 systems. The Apple Macs, Commodore, etc. were doing something else.
But the era of the PC Compatible is starting more with the XT and compatibles and on through the AT and 286, 386 and 486. DOS and Windows 1 to 3.11
Then the Pentium and some hold outs who didn't want to follow the newer PCI systems, the EISA and Cyrix, AMD, etc. The 586 group. Windows 95
Then the Pentium II and III. Windows 98/Window 2000
There are all sorts of other families that are not necessarily in this Intel/x86 path of progression. But most of my stuff is in this Intel/x86 family sonce that is what we bought into back in the early 80's. It wasn't until much later that I got some old Apple II's, Atari, Commodore, and Tandy.
I have several other computers in the Intel family that are not really "Vintage". Some people stretch to include the Pentium 4. But I don't really think of anything past the Pentium/586 class as even close to Vintage. I prefer to stop as the 486 class.
But I am with you. I wouldn't turn down anything if I had enough room and unlimited funds. But instead of trying to buy old CP/M systems or a Commodore PET I just read and watch videos, or use simulators/emulators. It's cheaper.
