They are really cool, really well-built machines, for sure!
I loved the description of your collection!

My collection goes way back. My wife is after me to pare it down, which I’m doing. I have some vintage Apple II machines from 1977, earliest is in the low 100s serial number I still have, another in the 300s I sold to pay for others, most likely worked on personally by the founders. They still work.
