These are some good hacks and tricks!
The good news is that these fun days are still upon us. I'm a member of the Bitshifters collective: https://bitshifters.github.io/
If only there had been an internet then, rather than just me with my books and a few years to spare :-) I guess most of us were like that at the time.
I see the 6845 still has surprises yet. Now you've made me read the Wikipedia article on it, and I learned something new, that it can be tricked into reloading the display address in the middle of a frame. If only I'd figured that out that back in the day, that would have been very handy!
I wish there was an internet back then too, one that was fast, had a good search engine or directory ... and was only online for 2 hours a day for research purposes. A 24x7x365 internet would have gotten in the way of my tinkering which was mainly driven by boredom.
