a bunch of faster/cheaper variants of the same theme.

My problem is getting started with all this. I don't want to drag the
old EPROM burner out of the basement; I think the latest fad (late as of
probably 15 years ago) is in-circuit programmability and -debugging.

I'm just wondering into which architecture should I invest time and
money in terms of a development system, and how much. Unfortunately the
app notes I found on many MCU vendors mainly cover embedded networking
applications and not the more down-to-earth stuff I'm interested in.
Like I said, I like m68k assembler but I've heard good things about ARM,
too.

Given your m68k experience, Coldfire would be your architechture. Consider
Coldfire a kind of RISC'ed m68k minus some addressing modes and
instructions. Have a look at the Coldfire instruction set, and you'll
recognize the mnemonics, thre A0-A7 and D0-D7 registers and much more.
