I was running Apple MacOS 7 on my Amiga 3000 as an emulation. Ran faster than it did on a native Mac with the same 68030 processor.
I’m still running WXP SP3 on a Dell Inspiron with a Duo Core CPU, 4GB RAM (3.25 recognized by XP), a 512MB video card with AVG and AntiMalWareBytes keeping it running squeaky clean.
Ad Blocker Browser plug ins amongst others keeps my browser free of ads.
I’ll probably upgrade to a SS HD from the 250GB SATA HD I currently have.
XP was the last good OS that Windows released, and I never liked the Apple UI, not to mention the price of the HW
And I still remember a lot of DOS commands.
