...except that, in my experience, finding old Multisyncs are just as 
difficult as finding the original AT&T PC 6300 monitors that go with the 
machine.  Both have similar frequency on ebay, anyway :)

It was offered to AT&T and Bell Labs employees at a very nice discount 
(almost half) so that's how I got one (father was AT&T employee) and 
that's how I saw a LOT of them at garage sales 5-10 years ago (I live in 
Naperville, home of one of the Lucent campuses).  I think it's not 
entirely coincidence that a lot of HAMs are/were Bell Labs employees...

I'm currently a Lucent employee, and I see AT&T 6386s by the trash heap 
about twice a year (386sx-16 machines, with the same AT&T 640x400 
graphics modes, and also VGA).

Some quick google and usenet searches shows the following very useful 
tidbits:

Lots of good info there.
