Damn, maybe I shouldn't be tossing crud like that busted VR290 in the
dumpster... All of those 14" monitors are worth 3 to 5 bucks? Heck, I've
probably tossed 20+ of them this year... As I write this the dumpster by my
work contains 2 dead terminals, a dead VR290, and Dell guts.. the MicroVAX
3100 may, unfortunately, be joining them soon, since it won't boot and all I
get is a ~ from the console :( But seriously, would it be worthwhile to save
all the circut boards, monitors, etc. which I currently toss in the
dumpster? I already have a bunch of automotive scrap that I know is
worthwhile (i.e. engine blocks, transmissions, etc.) but is that computer
junk worth it?

getting a ~ from a 3100 often suggests your doing something wrong.
I bet you cable is wrong or maybe the internal line fuse is open. If I
were closer I'd say bring it around and I'd look at it.

Generally yes, monitors need to 'look' good, no scratches or burnin on the
tube, and in most cases old terminals are not wanted. The MicroVAX 3100 is
full of goodies and gold. The other part is normal, you need to either take
to a salvage place that does the recovery, or have enough of a load to make
one of the "runner" type guys come and get it. The former is a better idea.
Don't be surprized if they try to low ball you, but don't accept anything
for a one load deal you would not be happy to repeat.
BTW you might want to check with your trash company, many places do NOT
allow a monitor or other large tube device into a landfill. If they find
one, and it still has your property tag on it, you could get a nasty fine.

Indeed so. I have just been emailing with a fellow who is a consultant to
the EPA and had contacted me for feedback as to what I do with defective
CRTs. He told me that Massachusetts has banned CRTs from landfills within
their state. Reason basically is the volume they take up. MA has a new law
promulgated which prohibits creation of new landfills so you can imagine
the remaining ones are a rather limited resource. (So watch out Allison and
Megan! :)
What do the rest of you folks do to get shed of dud CRTs? I suppose the big
scrappers handle recycling of the CRT glass through an outfit specifically
geared toward CRT recycling. I found there are at least 16 outfits
worldwide who either broker or actually recycle CRT glass and CRT byproducts.

I am NOT RESPONSIBLE for any injury caused by trying the above, BTW!!!
Modern CRTs can't violently implode, but it's still wise to take care.
I have included the caveat in the quote for obvious reasons. A master
at my old school used to break up old CRTs by _gently_ tapping at the
base of the neck with the ball of a hammer. This created a small hole
to release the vacuum.
It looked dangerous to me so I used the 'blanket and brick' approach as
in (c) above or put the tube in a dustbin and crouched down beside the
bin and used a hammer to knock off the neck keeping the bin between me
and the CRT.

You can safely let the air in (or vacuum out) of a CRT by breaking the
"tit" on the back end of the CRT where the air was evacuated. It may be
covered by the plug for the electrical connections. If it is then just
break the plug off. The glass is very thin there and I've seen may people
just use a karate chop motion with almost any metal object to break the end
of the tit off. That will let the air in and the rest of the tube stays
intact.

It depends on whether or not you are willing to invest a little work
in them on the off chance someone might need them. For example, I
took two dead Apples IIs and swapped parts until I got a running one.
I never was able to revive the other, so I ended up in the trash
(Sorry, I was ~15 at the time)...
Most DEC boards use the same bus transceivers that aren't available
anymore. If you were willing to make a list of the components on the
board, you might find someone willing to spend $$ for a dead board.
Clint
PS This is not an attack on throwing stuff away. Only a suggestion
for everyone (myself included) to revisit that stack of "dead"
hardware.
