I was thinking they're not quite that valuable.  Has one ever sold for more
than even 5000?  I admit I have never seen one on ebay or privately for
sale to know.

Not for $9800, can't afford that much dough.  The paddle color does not
mean as much to me, more interested in whether it's serviceable and
supportable.  I don't really have a strong preference other than "can I
make this run and do something with it".  I just wanted to be sure I was
not missing something about the 570 to justify what seems to me to be a
high price.  There is nothing that I could easily find that distinguishes
the 570 from the original version.
Thanks for replies...

Random question:
Would you have bought this one if it were maroon instead of blue?

At first i treated this as troll bait.  Then thought about it some.

First despite caveats I don't have space so the likelihood is nil.
Also its outside what I do collect, that crates conflicts for space,
power and documents.

The reasons I could give for one or another are multidimensional.

Esthetic, the early 11/70 was of an era and that had a look.  The later
one as well.

Historical significance,  thats limited to the general model the biggest
fastest 11
made but having say serial number 001 or whatever was first off the line
for sale is
as significant as the last one off the line or both.  Also any along the
way that had
a instruction set or major hardware difference of some historical note. 
An example
of that would be an 11/74 as those were truly rare (maybe 4 assembled).

Operational, as in running it. definitely a late model near last built
as it would
have all the ECOs, be the least old, and should run well

Opportunity to save a machine that might be scrapped.  In itself thats
important
and it would be model independent.

Being a Qbus 11 collector there are still critters I might gather.

Luckily for me the local computer club has both the maroon model in a 
H960 as well as the blue corporate cab model. So while space is a bit 
tight I don't have to consider it :)

I have spent more time with the H960, so I might be biased. But ignoring 
any subjective preference for color I do prefer the H960 simply because 
it is easier to work with, less bulky metal panes to remove in order to 
gain access to the CPU. And it is easier to move arround.

This seems like a very pleasant problem to have, are you facing the 
choice?

/P

I think the decdatasystem 570 is pretty, but coloured like an ice-cream
parlour.

I prefer the darker motif of the standard 11/70 posed with a string of RP06
drives, much like the original cover of the PDP-11/70 processor handbook, I
think that remains iconic for the "biggest" PDP-11 (biggest for the SSI
logic implementations of the mid-1970s).

Random question
would you prefer having, if you had to pick only one, the original PDP
11/70 or the newer "blue cabinets" PDP 11/70, assuming both were complete
configurations with racks of storage etc as they would have been sold, more
or less.

Assume space and power are not issues, consider just the machine itself.
