I was reading your wall of text chomping at the bit to complain about IRQs and dip switches but you covered even that!
Oh wait, you didn’t include having a math coprocessor daughter boards! I barely remember them but remember my dad building computers with them.
I kinda wish I was a teen when the first computer kits were coming out. And phone phreaking.
Jokes on them. I randomly select extra or less boxes than are correct. Yes, it takes me more time but I’m doing my little part to stymy Skynet.
