Problem 1) Whenever the CPU is doing something or something is being
read or written, faint warbling screeches can be heard coming from
inside. The volume control does nothing to quell this noise.
This is likely subharmonic trace resonances in the CPU board. I don't
think you'll be able to do much about that.
Problem 2) The image on the monitor is canted a few
degrees clockwise --
enough to be noticable and irritating.
Power it off. Pop it open, slightly loosen the clamp on the CRT's
yoke, and turn it a bit to correct. BE VERY CAREFUL, and DO NOT DO THIS
WITH THE POWER ON. There's serious high voltage in that area.
Problem 3) I've figured out how to format a Mac
floppy under Linux and
transfer files by floppy, but I'm unclear how I should get two needed
utilities: binhex and unstuff onto a Mac floppy without mangling the
resource and data forks.
This is a guess, but I believe there's a Linux implementation of
StuffIt which might help with this. (I know it was ported to UNIX; I
have the Solaris/SPARC version)
