The risk is that you'll generate a bunch of chatter about what the amendment was supposed to do even while it's clearly stated in the comments.
It predates my lifetime but it’s been really fun to learn about how stuff used to work. (Which I guess is some form of nostalgia)
There’s a bit of a boom in retro computing in general right now. Many independent makers doing hardware and software with cool blogs or YouTube channels.
The funny thing with all of this interest in the computets of my childhood, I have grown more interested in the computers that came before my lifetime.
