Re: VAX-11/780 Board Set on eBait

Well I am still holding out hope to find a vax 780 and get it running. I
did not think i would ever be able to find a pdp 11 , but one crossed my
path and i managed to pick it up. Perhaps one will still show up around
here somewhere. In the meantime ive been trying to stockpile parts for the
one day i do manage to find one and it need a board.

I hope that "a machine" wasn't 'an empty machine to plug them into' - because
AFAICT the chances are that happening are basically zero. (People seem to
save either i) complete machines, or ii) just the boards - apparently not
realizing that without the backplane, etc, the boards are only useful as
spares.)

For some reasons, /780's seem to be pretty rare. I suspect it's a case of
'they were mostly all scrapped long ago in favour of later models which were
faster and smaller' (we see the same thing in other lines).


Don't get me wrong, I truly do fervently hope that you do find one somehow,
but one has to be realistic, I think. (I'd love to have an RF11, but I'm
pretty sure they almost all went to the big scrap-heap in the sky many moons
ago; so I'm not holding on, waiting for one to appear - rather, I'm getting
on with the stuff that _is_ still here.) Sorry to be such a downer... :-(

It looked like a good batch of boards and i was holding out on finding a
machine. Any good place to get a 11/780 aside from watching the local scrap
centers with my fingers crossed one will be there?

I'm going to start that with my 780 soon. I'll probably snag the eBay
parts if the price stays reasonable and I'll let you know how things
go.

BTW you mentioned you had had problems with your 730 main breaker too?
How exactly was it misbehaving? Did it sometimes refuse to power
machine even when it was in the ON position?

If anyone is desperate for VAX-11/780 parts, let me know -- a friend of
mine recently came into a load of them.  If it can help someone bring a
/780 back to life, he'd be up for working something out...

Sorry, I didn't mean to upset your plan (and you); I just didn't know if
anyone was watching for VAX-11/780 parts, they come by so rarely.

We have discussed this topic before, but let me recapitulate one point about
pricing and valuations: if we want to stop this stuff being scrapped, we need
to make sure the prices realized are well above scrap. This will have several
consequences:

i) If people only get low (scrap-region) prices, why go to all the
bother/hassle of listing things on auction sites; just proceeed directly to
'Go'. ii) Hopefully, if values are non-trivial, the word will get around, and
people who have this stuff will go to the effort to list it, instead of
leaving it to moulder, etc.

Yes, I understand that will make this a more expensive hobby, but TANSTAAFL.
YMMV.

There's no such thing anymore of seeing a classiccmp-related item on ebay 
"under the radar". Everyone looks.
Think of that radar lower limit like the head/media gap... around 25 microns ;)

you can go for the belt buckle.  Actually, wonder if it is an estate 
find, or if they scrapped or plan to scrap the rest of the machine. That 
is always concerning in these cases.


I bought the recent 6120 sparetime one from Doc Shipley which was for 
sale recently, had the same problem but on the STG yahoo group.
