Some mention has been made on the list with regards to a "global" list of
classic computer related artifacts, be those documents (manuals), software
bits, other historical ephemera, etc. The concept I've been working with is
defining a standard record format for interchange amongst those that wish to
participate. Think of this as something like ANSI X.12 (Electronic Data
Interchange).
Each site who wants to participate would (in an automated fashion)
periodically (nightly?) run a program or process that takes data about their
collection items and puts it into this standard record format. The format
has things like document name, title, description, document type, owner
site, http vs. ftp, URL, FTP address, email contact, date, key words,
categories, distribution allowed, etc. For example, a program could pretty
easily be created that would take all the documents on bitsavers and puts
them into this standard record format. Then the source systems send this
record dump (or deltas from a previous dump) to the classiccmp server.
The classiccmp server takes all these records from all the various sites and
puts them together into a single database internally, and also provides a
seamless mechanism (http, and yes... gopher, archie?) for people to search
the database or browse based on given criteria. It looks like one database.
But when a user tries to pull up one of the specific entries it is actually
redirected to the sponsoring systems server to get the data.
This way each system can keep their classic data (jpegs, pdfs, disk images,
whatever) in the format they are already using without changing anything.
They just need to have something that takes their format/sources and puts it
into the standard format which is then sync'd to classiccmp.org.
Provisions could be made to the standard record format to address all types
of media, allow some items to be listed as "present" but "unavailable" for
things that can't be released due to copyright issues (but at least people
would know it had been preserved).
I'd be happy to start a separate mailing list to discuss this record format,
and if people are interested in participating. I'd hate to chew up
cctalk/cctech bandwidth discussing project design :)

CMU did a parallel machine like that using PDP-11/40s. They used 16
machines and 16 memory banks. It was called C.mmp. I think for me,
reconstructing that would be the ultimate in classic geek.
Also, while I haven't watched all that carefully, I'm sure there are others
who have also used crossbars to route inter-processor communication.
I even messed around with that approach a little.

In answer to mikes question... Yes and on a lot of levels ...
BUT I am in full agreement with Jay that it is OT for this list and further discussion it does not belong on the cclist
at this point in time. So I have place my reply and some thoughts on the subject in a seperate Blog.
http://computercollectables.blogspot.com/
I invite others to come and comment on mine mutterings or create a free blog of their own, on this or any other
computer, collector, collection, or collectable related subject. I like the idea that Blogs on related subjects can be
cross linked using comments to form a better overall picture of the challenges involved in building everyones
collection and archive management solution.
Sorry Jay for the additional waste of bandwidth ;-)
Please comment directly or in/on the blog NOT here on this list!

Folks,
My local favourite DEC reseller has the following heading for the scrapper
unless someone pipes up:
8 or 9 Alpha 3000-300LX with RAM, working when pulled
10+ DEREPs
VAX 3800 cabinet, no cards
R400X cabinet, no disks
5+ VXT2000 x-terms, base unit only
5+ VXT2000+ x-terms, base unit only
They've been stored outside for a month so they've had a good wash in the
british winter, but they'll be fine once dried.
You pay packing/shipping, I'm happy to box up and send to wherever, there's
palletising facilities at work.
Caveat is, the stuff will probably be heading to the recycler in a week's
time so speak up now.
Cheers,

Well, unlike the Altair, a computer that didn't run any software wouldn't
have sold very well in 1979; what do you call software, and how much'll
you let me expand it? They did have BASIC, Forth and PL/65 (and an
assembler of course), Serial I/O and two expansion busses, but although
you could connect a terminal and disk drives I think CP/M would be a bit
of a challenge... wouldn't want to run a Fortune 500's accounting on
it and end up like the Enron & Worldcom boys (and our very own
Lord Black of Crossharbour, presently starring in Chicago ;-).
But being (AC-powered) portable with a full keyboard and an integral 20
or 40 column display & printer, there were quite a few applications for them
on their own (e.g. insurance agents used them on the road, later moving to
the more or less functionally equivalent but smaller Panasonic HHC).
They were also used a fair bit in the lab & industrial area.

I have to compose a much longer post about everything discussed in the past
week while I was gone. I did want to say thank you to Jay for supporting the
main bitsavers archive site, and that I support whatever he would like to do
to continue hosting it. I am a believer in preservation through replication,
which is why there are public mirrors of the material.
More thoughts as I finish going through everything discussed while I was gone.

It's possible since I configured that system nearly 10 years ago and it
hasn't been opened since save for cleaning the fans. The only board that
could have a boot rom would be the RQDX3. I'll have to check net time
I clean the fans.
