I'm paranoid enough that I didn't want to come in contact with any part of
the CRT at all. I wasn't worried about moving the yoke, I was worried
about it biting me. It's nice to know that with the power off there
wasn't any danger though.

Changing the pinout while everything was installed was a challenge,
When I was working on the Z90, I found it helpful to rememebr that it was
a Z19 with the processor board added (making n H88) and then the floppy
disk system added after that. And that it was best to remove things in
the reverse order. Take the floppy drive out first, then the add-on
boards, then the CPU board and finally the Z19 board, etc.
especially while simultaneously trying to avoid
touching the yoke on the
CRT neck. :)
I assume you were doing this with the machine turned off. In whcih case
what's the problem with the yoke? It's not a colour CRT so there's no
real alignment problem if you do slightly move it. There's no stored high
voltage on the yoke.
