Imagine if you went to see a play in the theater, and every few minutes it just *stopped*. And you had to wait while the actors set up for the next few lines of dialog, and the director chatted with the lead about motivation, and commentators ad-libbed to the audience about how the scene was going.

It's on Archive.org of course. But it would be cool to have the dead-tree version!

Not strictly for 6502, and maybe obvious, but...
If the last thing your subroutine does before RTSing is JSR to another subroutine, you can replace the JSR with a JMP and omit the RTS, saving a byte and several cycles.

I once toyed with the idea of using indentation in 6502 assembly as Pythonesque way to branch without labels.
I started on a proof-of-concept preprocessor to read the weird code and turn it into standard assembly. Not sure why I abandoned it... might revisit it one of these days.

That's a good point. Certainly by now, Spinal Tap has pulled a full Monkees and gone from manufactured to legitimate.

I've got the same radio in my kitchen, in a different color scheme. It sounds pretty great for the size.
(And yeah, sometimes I hook an 8-Track player up to it.)

Is a relocatable stack pointer even that important? I've never run into any problems not having it.

It might be too on-the-nose, but I don't care. If you start a roadtrip by blasting this song, that trip is legally required to be awesome:
