Well the QMC maths building was new enough to have been designed to

I get the same thing every Autumn, both in my car and with the
Dimplex night storage radiators. With the latter, they also give off
fumes from the epoxy resin which are quite nasty. For the first few
years, for the first day or two there is a layer of air up to 3 feet

are supposed to filter out dust, so if there was dust in the heating
coils, does this means it was not working properly?

Hi,
> That looks specific to a CD-ROM....
Actually, that what I was thinking.
One of my Yamaha CD writers (I think the CRW-2200E) comes in EIDE and SCSI
flavours, the SCSI one being merely the EIDE drive with and adapter
according to the docs I have.
I'm wondering if this is the adapter I need for mine, though I think the
2200E adapter adapts to 68-pin SCSI (this looks like 50)?

I'm guessing it is: There's an external motor in one corner of the unit; I
can't read most of the label, but the "0.9 deg./st" that I can see would
suggest it's a stepper.

OK, that will give me something to work on, once I've figured out how to
re-assemble the thing whilst leaving the control board accessible....
I couldn't tell you if this was a normal ST506 i/f. The control board on the
drive has "TM600 uP 187345" printed on it; the Sirius' controller board has
only "XEBEC SYSTEMS INC." and "Assy 104526 rev-07" as identifying marks.
Does any of that help at all? I've not looked for any schematics yet, I guess
that's the next thing to do.
Cheers,
Ade.

Hi, all,
I'm back in Madison, WI, for the summer, starting another South Pole
tour by coming into the office, ordering a bit of this and that, and
doing a bit of training. I have wheels, and potentially some free
time here and there. If there's anyone in the area, especially anyone
into DEC hardware, Commodore hardware (PET and/or Amigas), or 1970s
micros (1802, 6502...), perhaps we can connect.
Either way, I'm still in striking distance for VCFmw and should see a
number of you there.

Here's an odd one for you:
Coast To Coast AM (UFOs, Ghosts, ETs etc.) has been running a story
about strange spacecraft buzzing around (where else?)
California. Recently somebody claimed to have spent the 1980's
working at a secret lab in Palo Alto trying to "commercialize" the
extra-terrestrial technology:
http://isaaccaret.fortunecity.com/
Now, veracity-wise, these photos and "documents" have problems:
- Nobody is coming forward and identifying themselves.
- In the top-left and top-right photos, if the camera exposed the sky
for a neutral blue, the underside of the craft would be very
under-exposed (almost black) like the middle photo and the underside
of the leaves and power pole.
- If the lab was as secure as the author claims it is, "TOP SECRET"
or somesuch classification would be clearly stamped on every(!) page.
- The final problem is with the look of the documents. While there
are some nice touches (three-hole punch marks on the cover...remember
those ubiquitous binders?) the documents have nice fonts and
formatting, and look laser-printed.
Now, in 1986, the number of systems available capable of producing
such documents "in house" was fairly limited. You did have the
LaserWriter, but it had just come out and the document doesn't look
like it's using one of the original LW fonts. The other options were
Scribe, TeX, Xerox, maybe InterLeaf...and not much else. Integrating
a digital photo into a document was a royal pain back then, and
scanners were still exotic equipment.
I'm curious - does anybody recognize which system produced the
documents? I'd be impressed if hoaxers went to the trouble of
tracking down vintage equipment to produce them.
Overall the story the web page tells is pretty entertaining. One
wonders if this is a viral marketing campaign for a sci-fi movie next year.
Cheers,
jp

The local scrapper I deal with does a fair amount of business picking
up the remainders of local auctions for folks that only want an item
or two. You might check to see if there are any liquidators in the
area and see if they will take what you don't want - this will save
you the cost of hauling it to some scrap yard.

Found some more stuff that I'm unlikely to use
(1) the free stuff: Anyone need a LaserJet Series II for parts? It's
having fuser problems, but if anyone needs other parts it's here. I
also have some (EP-S?) cartridges for LJII and similar modules.
(2) the probably not-so-free stuff: One Multibus SkyFFP-M-03 FPA card.
As it is currently it has the IRIS extender on the back (IRIS Multibus
cards are almost twice as deep as the "standard" multibus so they have
a aluminum plate to extend the eject levers). Preference given to IRIS
1000/2000 owners, but I think it's the same part used in Sun-2 Multibus
machines. Weitek WTL1516AJC based.
