Ah, a fellow KISS fan. :-) I got started on Unix by going from CP/M at
home to hanging out, circa '89, with some folks who sat me in front of
a 21" color monitor connected to a MicroVAX or the like, (very hot,
not to mention expensive, stuff at the time, like getting out of a '59
Volkswagen and into the cockpit of the space shuttle), gave me a few
manuals and said, "Do Something interesting".  Those machines use a
Posix non-compliant wm (uwm, Ultrix Window Manager, IIRC) with no
borders, buttons or other trim.  With Linux at home, I've moved up to
twm and stuck there.

Same here.

I don't do it that way.  But normally, I access the net (from home,
via ppp) with only my main box.  That's gradually changing because
there's one site -- there'll eventually be more -- for which I have to
use the recent browser on the laptop to render it readably.  Normally,
I connect, do mail, news, web etc. just from the one machine with a
modem plugged into it. (And use a very old browser, so old that it
doesn't support any of the popular attack vectors.)

Right. All your remarks and pointers saved for lookup next time.  And
there's always a next time.  :-) I once asked, on our local Linux
mailing list, about implementing analog audio from a CD drive. Was
instructed about installing the right cable that was missing.  Did
that, all was well.  Some weeks later I was gently reproved for asking
what appeared to be the same question over again.  But it wasn't the
same.  I had bought a new internal CD drive, found and plugged in the
right cable, got no sound.  Eventually, after grovelling around the
net, found the mfgr's manual for the drive.  The physical plug for
analog audio was provided on the drive but marked on the manual's
diagram as "not implemented".  Grumble.  The fellow who had reproved
me opined that that was "not fair" by way of apology. :-)
