Way back when, I developed a Z-80 based embedded unit complete with a

Anyone hacked their Z-80 with a analog meter yet?
Seems the easiest
(just pull off of the M1 line).
That'd give you a fairly constant reading...not very exciting.
Not many Z80 systems have variable clock rates. Though building one
wouldn't be difficult.
