Name something that was old school to you. Or post something that is more old school that a previous poster. Be real
My first PC was a TRS-80 modded with a piggy backed 1K memory chip to enable lower case letters.
(No matter how old school I think I am I know someone is way, way more old school than me. I expect someone will tell me how they had to rewire their computer to program it, or cut new gears for their Babbage Engine )
