About 1 hr in, a "computer" is used to analyze flying saucer
messages. It's a Bush-style (no not our dimwit president, the MIT
guy) diff analyzer! Operating! With plotter!
TiVo'd it. 1956 Harryhausen movie. Haven't seen it since I was 12!
Lyle,
I tried to reach someone at dilog.ch (the european branch office) to obtain a manual for the
Dilog DQ3256 controller ( a very good SMD-E Controller), but unfortunately, nobody answered.
I just gave it e try, as I heard, that they still sell and even produce some qbus and unibus boards.
Maybe, I should write to dilog.com instead of dilog.ch?
Regards,
Pierre

I'm starting to sort all the DEC stuff that I've been picking up the last
few weeks and I've got a big pile of the CAB kits sorted out. I know that
several list members wanted some of them so I've decided to to offer them
to list members for $8 each plus shipping. Shipping should be $3.85 in the
US. Buy as many as you want for one shipping price. If you're interested
contact me directly for details. I'll pick out the best ones to send out.
They should all have both cables, all the knobs, etc and appear to be in
good condition. The batteries are old and probably dead but don't show any
signs of leakage. If you don't need cables, let me know and I'll save the
ones that do for those that need them.

I picked up some of the decorative plastic panels for the DEC computers
yesterday and I plan on listing them on E-bay later today.

DEC items on E-bay as I have time.

This past weekend I picked up an old PS/2 machine. It's a Microchannel
system, a Model 65sx (I think). The only thing missing in it is the
hard drive. It has one of those 3-1/2" drives with the full-length
card-edge connectors on it, I think 50 pins wide or so, that provides
all connections including power.
I would like to get it up and running just to have around as another
working system (also got a Compaq Portable III at the same auction for
$10 in a leather case!). Any suggestions where I could find such a
drive easily? Is this machine's HD interface an ST-506 variant, EISA,
or what?
Thanks.
(also got six complete, loaded Ultra 5 boxes at the sale. Exciting
times...)
Our very own Chris Garcia has an interesting article on movie computers at:

For those who don't know what fanzines are, I will leave that up to Chris to
explain in some future issue.

Hi Tony
I don't know specifically about silver ( one of the better
reflectors ) but the more common reflector, aluminum, is
down in the few percentiles at these wavelengths. Silver
doesn't hold up well in the current atmosphere because
of sulfur in the atmosphere, both man activities and natural
sources.
There are what are called dielectric reflectors that
can get into the high 90%'s but these are for relatively
narrow band widths.
For all practical purposes, the higher frequency UV just
doesn't reflect worth beans.
I put aluminum in my EPROM eraser, more to protect the
plastic from UV damage than to reflect much light.

Hi
The mirrors most likely don't do much more than any other
surface. At the wave length used to erase EPROMS, about
the only thing that will transmit the light is quartz.
ordinary glass used for mirrors only allows a tiny
fraction to pass through.

I was recently scanning the web for a Dilog SCSI board and stumbled across a
"DLI Dilog" web site: http://www.dilog.com/unibus.html
I called and chatted with Jon Klotz - who turned out to be a founder and
partner of the original Dilog back in 1978. Amazingly, DLI Dilog still
manufactures DILOG boards (mostly SCSI - but some serial) primarily for
government accounts.
As one might expect, the price of new boards is prohibitive for most of us as
collectors ($2,500 or so for a SCSI Unibus or QBus board). They don't stock
boards - they manufacture them from scratch when they get an order!!! They
are capable of manufacturing a brand new board for every product that Dilog
ever produced!
Jon was great to chat with and knows a lot of interesting DEC history!
I was just sorry he didn't have a stack of used boards he wanted to part
with ;-)
Cheers,
Lyle

"Black holes are where God is dividing by zero"
All this talk of 2708s and how to program them makes me wonder....
I've got some PROMs of various sorts (mostly UV-erase, but a few 28xxx
EEPROMS). I'd like to throw together a burner. But to this end, I
find I care about things such as differences between one maker's 27512
and another's.
Is the sort of trouble described for the 2708 something that was worked
out of PROMs early in their existence, and for later devices I can use
pretty much any manufacturer's data sheet, or do I have to make sure I
use a reference that corresponds to the exact maker and chip I'm trying
to write? If the former, what counts as "later"?

In the whatinthehellisthat department:
I have a small daughterboard, pulled from an very early Sun SPARC machine
(perhaps the first generation Sun-4 architecture). The floating point chip
was replaced by this daughterboard. On the daughterboard is the PACT8847
chip (the normal floating point unit), plus a larger chip called
100-1845-1 SUN-GNUFPC. The daughterboard seems to be called GNUFPC COBRA,
and seems like real Sun hardware.
Ideas?
