Summary: I use a remote printer


Brandon mentions that his printer caused a preculiar slow motion
effect similar to what I had accompanied by the "too many windows"
message.

I have a printer set for remote printing via uucp on neoucom's
imagen 2400, so I don't have anything currently attacted to my
Centronics port.

The had the peculiar slow motion effect once since I removed the
one additional escape-hatch getty.  The only job running at the
time was vi, and I had been using vi for about 10 minutes.  Neoucom
had just finished a big uucp transfer just as I began vi.  Of
course, the necessary daemons were running too.

So far my system has been up since Nov 21 (knock on wood) and there
haven't been any of those weird happenings since then.  I really
haven't changed anything radical (other than temporarily unloading
The STORE! from my disk).  Perhaps, the machine was just burning-in
for the fist few weeks and needed to make friends with me.

About the only other thing I can think of is that for the first few
weeks, the electrolytic caps in the power supply were unstable.
Judging from the date-code stickers inside my machine, it was
sitting in a warehouse someplace for about a year before I got it.
In that time the filter caps might have degraded.  Apparently, the
72 meg (er, I mean 67 meg) drive was popped into the machine just
before it shipped from AT&T last month.

I used to manage a student lab with about a dozen Apple II
computers.  Almost every Apple we received crashed repeatedly for
the first few days, and then would be fine for several years there
after.  It must have been filter caps, as the power supply light
blinked and chirp! chirp! would be briefly emitted (presumably)
from the switching regulator xformer core.

I'm getting almost bold enought to put the escape-hatch back in and
see what happens.

Thanks to all the Net People that have written with their
suggestions.

Happy holidays,
Bill
