its only a couple of years since I had to rebuild a Windows 3.11 machine that had been struck by lightning. It ran a milking parlour, and economics couldn't justify the upgrade of the software. I found a scrap 586 motherboard, cpu and fan at the local tip and reinstalled DOS 6.22 and Windows 3.11 from a collection of .IMG files copied from a bankrupt former employer. It worked, wasn't internet connected and simply did one job. No need to upgrade.
Thinking about it, I was probably the only local tech who had access to the required images. Lucky for the customer!
Its only about three years since I had to rebuild a specialist piece of opticians kit (one of the machines which measures field of view with random flashing lights). Needed a new fan and hard drive - again, the local tip got raided when no-one was looking. Replaced the software like-for-like with DOS5
