It sounds to me like one of the front panel buttons is getting stuck on
somehow. (or footpedal if you have one plugged in.) I just turned one of
mine on while holding the Next button down and it pretty much behaved just
like you describe. Try all of the buttons and see if any feel like they are
sticking. If they are, it might be that the top piece of metal got bent
down a little and is pressing against the tops of the switches. That used
to happen to me with prototyping the things because I always had the tops
on and off and never used the screws, so eventually they'd get bent somehow
and interfere with the switches. Or maybe that hole has some little metal
spur or dirt got in it or something.

If that's not it, then it would be something weird like a bit of metal
floating around on the circuit or something. Or maybe some part of the
circuit just broke, but that seems a bit unlikely for what you describe.

Pat Murphy <pmurphy@gibson.com> is the dude you want.

If they had a contest for most boring/ugly architecture on campus, Tolman
would be a contender. I think the only class I had there was a discussion
section of electro-magnetic fields and waves, which may be influencing my

oh wait another Tolman experience....summer after 8th grade I took a math
summer school class at Berkeley, and they would have these optional/fun
lunchtime classes as part of the program. I took one where this goofy math
teacher from some suburban high school taught us how to break dance. That
was in Tolman. In retrospect, completely surreal....
