I wonder what the really ancient Mac he links to was. The link is broken since Apple has since drastically redesigned their support site at least once.
One of the horribly compromised x2xx series Macs, which did 64-bit operations through 32-bit, 16-bit and 8-bit buses to save 10c on a chip. Quite possibly the most compromised Macs ever built. I used to have one, we called it the "iTurd". It could just about crawl Mozilla 1.3. We eventually just used it as an oversized desk clock.
Ah, yes. Somehow I was fortunate enough to skip over that. My first couple of Macs that I remember getting second- or third-hand as a kid were a Performa 640CD DOS Compatible which was actually not bad at all, and had the interesting property of containing within it a 486 on a daughtercard, and then later a Power Mac 7200, which wasn't great, though at least had PCI and managed to avoid the Road Apple designation from LowEndMac.
