Yes, but I don't feel like hunting down (and paying for) a tool that's
really only good for this one job. I've only got the one Mac, and I don't
plan on opening it too frequently.
Now, if I got a whole truck-load of old Macs and was threatened with death
if I didn't open them all up, I'd certainly want the proper tool. :)

I just bought a 'cheap' Radio Shack logic probe today, also 10MHz.
Unfortunately, tonight I was powering it with a cheap Radio Shack power
adapter, and it was screetching and had the PULSE light on no matter where
I made contact. So probably I need a power supply with better filtering.
I know that when I used to use this very same power supply with my
Walkman, there was a very audible (and annoying) hum.
Anyway, I don't know what the heck I'm doing with this thing yet. But
I've only used it for a few minutes. I didn't find the problem with the
Mac, but that'll come in time.
I also did a very dumb thing today in that I bought the wrong connectors
for the Mac->Amiga mouse cable I wanted to build. I bought one of each
sex, which any lame-brained dimwit would recognize as wrong as the two
machines in question use ports of the opposite sex.
If I had accidentally bought two female plugs, at least I could've tested
the Mac mouse on the Amiga.
My excuse is that I haven't managed to get more than 4 hours sleep on any
night so far this week. :)
At least I'll be building up a 'spare parts bin' like the rest of you. :)

Thanks for the advice and info, Tony!
