Today I upgraded an SE to 2.5 megabytes using SIMMS from Technology
Works. Everything went fine considering that this was the first time
I'd opened up a Mac, but after booting the machine I noticed that the
speaker was behaving erratically. Sounds would begin but would then be
cut short or degenerate into static. Sometimes I couldn't get any sound
at all. I opened the case again and checked the speaker cable
connection, but everything appeared to be in order. The problem was
still there when I started it up again.

Setup:  2.5 megabyte SE running System 6.02 (problem occurs under both
Multifinder and Unifinder)

A coworker suggested that there might be some oxidation particles on
the contacts. From experience with stereo hookups this makes sense, but
I wonder if anyone out there might have had a similar experience.  If
anyone does have any experiences or suggestions, then please e-mail
them to this account and I'll post a summary to the net.

Thanks in advance,
