A nice little RT-11 system. It may seem heavy, but the alternative
is usually in a BA23 deskside/rack box, and that's heavier. It is
almost completely non-expandable as Tony pointed out; it was
theoretically available with only a single RX01 floppy drive, and
three serial ports, but all the units I've seen (mine or pictures
on the 'Net) have both drives and six ports.
There's probably *something* other than RT-11 that'll run on it,
but I haven't gotten around to finding it yet. There probably
isn't enough room on an RX01 for anything like Xinu or a Unix v6
mini-root, let alone enough hardware, but things that could be run
on a pdp-11/03 stand a chance. Should be some fun things in the
DECUS library.

Sorry, meant to post a "seen this" note, but life got in
the way. That was a relisted at least once, I saw it the
other week and it ended with no bids.
What I need is something like the Google search API but
for eBay, so I can wrote a nice little 'bot that will
keep an eye out for things...

Trying to find an Overland Data, Inc. OD3201 (or similar)

Oh yes, the RetroComputing Society of Rhode Island is still very much in
business (www.osfn.org/rcs). {As is the Rhode Island Computer Museum
(www.osfn.org/ricm).} I don't know why you couldn't get through by e-mail,
other than the fact that "Shrimp", the RCS/RI's faithful Sun server, has its
good days and its bad days, and it's anyone's bet what today is. And I
don't know whether the phone is still there or not, but unless it's a
monthly Open House it's a crap shoot as to whether anyone's on-premises to
pick it up. I for one don't subscribe to Classic Comp, so this was kindly
forwarded to me by Marc Bileau, who is very active in the RCS/RI's
activities. He tells me that even non-subscribers can send to cctalk, so
here I am. Please respond to me directly, not to the mailing list.
So, just what is this item up for auction? I doubt we're bidding on it in
any case, as money is a bit tight all around right now. But if it's good
we'd be delighted to receive a donation.

Yes and no. There is a dual-height version of the 11/73 (KDJ11-A)
which carries the processor, MMU, FPA, cache control, etc, but no
bootstrap, SLUs, or line-tme clock. It was commonly sold as an OEM
product or as an upgrade to 11/23 systems. There is also quad-height
version (KDJ11-B), the same board as as the 11/83, but (if sold as an
11/73) it has a 15MHz crystal instead of 18MHz, and would originally
have had different bootstrap ROMs.

I was perusing some old DEC brochures, and I read that the AlphaServer
4000 can be field upgraded to an AlphaServer 4100. How does one go about
doing that?
Peace... Sridhar
G'day,
You posted a request for !EVX0101.CFG on classiccmp. Unfortunately, I
don't have one; I'm looking for !EVX0002.CFG myself. So far I haven't
found any mirrors of everex.com or an archive of CFG files, but here's a
clue:
http://groups.google.com/groups?selm=UTC200211161343.gAGDhQI15309.aeb%40smt…
I'll be contacting Andries.Brouwer(a)cwi.nl, perhaps he will make his archive
available.

Econet fileservers were called 'Filestores' which came in different 'levels',
which is somewhat like a version number.
Check http://www.heyrick.co.uk/econet/ for more information.
There was an Econet interface card available for PC's, called 'Ecolink'.
With this card I believe it was possible to hook an Econet to an Ethernet,
and/or to set up a PC as a fileserver.
I think it would be easier to set up an A310, A3000 or A3010 as a fileserver
though.
Another option which I've been working on is adding an Ethernet interface to
an BBC, and writing a simple TCP/IP stack so that this BBC can act as an
Econet-Ethernet bridge, but this project is still in the design stage :-)
Some econet documents can be found here:

Does anyone have any experience with Acorn Econet (Acorn's low-cost,
fairly low-speed network)?
My newly-acquired Acorn Cambridge Workstation (ACW) has an Econet
interface (I am told it's standard on these machines), and I'd like to
hook it up to something.
Digging in my junk box (well, more like junk room :-)), I've found a
couple of Econet clock boxes (one Acorn, one SJ, these supply the data
clock for the network), a terminator, various connector boxes, etc.
Cabling shouldn't be a real problem either, I assume the right cable is 2
twisted pairs with an overall screen.
I believe I need a fileserver (== a machine set up as such). Assume I
have Beebs (with Econet interfaces), 6502 and Z80 second processors, A310
(but no backplane, therefore no expansion), A3000 (no expansion either),
A3010 (in bits, but probably repairable), a couple of Systems (one with
an Exonet interface), and not a lot else. I think I could find the Acorn
SASI/SCSI host interface for the Beeb if pushed, and I have a Beeb with
the Torch SCSI card and SCSIFS. Oh, and an Acorn Econet bridge, but
that's fairly useless at the moment...
Any ideas as to what I should use, and where to get the necessary
software. Has anyone ever hacked a PC to work as an Econet fileserver?
The hardware wouldn't be too bad, I think.
Anything else I should be aware of?

Apart from auto tuning? I'm not sure. The manual for the extension is
on the net at The BBC Lives! but it's a pretty big PDF file :-(
