Nice VRAM conflicts going on there...

I remember those.
Kids today...

Now that would be an interesting PCB
That's a lot of free time...
Not a chip tune fan?
Kids today... Why, when I was young, that was the only music we could get out of our hand-held computers.
Been there. Done that. Years ago when that was the only way. Do it now? No way. Much better tools to do much bigger things these days. It's called progress.

Kids today... Handheld computers? Only if you were a champion weight lifter with HUGE hands...

It's an educational computer. If you've been there done that, you're not the target audience. This is like learning your shapes as a toddler. No one in geometry class is going to be trying to fit the star shape into the square hole. (One would hope.) But if they had never been exposed to that kind of toy, calculating angles is probably not within their grasp.
As someone who has used a computer all their life, this kind of thing removes the veil of mystery from the little chip under the giant heatsink. It's no longer a black box, it's just a very complicated and incredibly fast descendant of the PCB in post #1.
I realize this is probably all obvious and you're just voicing your personal disinterest, but the last line in your post plucked a nose hair. This isn't anti-progress, it's just simplified to make a complex concept more accessible.
They made us build state machines in the intro to digital class in college. I think that did an excellent job.
Hang on, that board has no decoupling, what a poor example to set.
Maybe that's one of the lessons.
"It doesn't work! It keeps crashing!" "Yep. Won't buy a board with no decoupling caps again, will ya?"
that board has no decoupling
That was my initial worry as well. The decoupling caps are hidden under the chips.
I find this a little too primitive to be useful, even as an educational tool

That's what happens when a highschooler makes things with "no formal education in electronics".

Ah, those IC sockets with built-in decoupling caps? I remember those, sneaky....
Given the spacious layout adding an LED/resistor to every signal line would be
a nice feature to add...
(oops. The board with the caps under the chips was a different recently posted logic-gate computer.)
This one does seem to be lacking in that department.

Aw c'mon. Granted, it's an oversight, but an easy one to rectify. He'll learn with experience. On the other hand, finding someone at that age focused enough to learn the building blocks of computing to the degree where he can build a simple prototype CPU? That's pretty impressive. I was still toying with BASIC and being proud of myself for assembling my own PC!
