Do you know how many of those week lost at Queens Park?? One guy in my
department nailed CRTs 2 in one week... You never forget that "hissing"
sound that comes out of the unit... then the expression on the person
working on it. The SEs also had those bad hard drives... the Principal
Secretary actually had a large screw driver next to his SE... Every time the
drive wouldn't spin up he would beat the crap out of it. Apple came down and
they agreed to replace all the flaky hard drives free immediately.
Entire legislative assembly had those things everywhere. I was visiting one
MPP (member of provincial parliament) and will never forget what he did.He
hated the SE so much that he actually asked me "how do I get a new real
computer?".. I told him the only way was if this one broke. .. Well, in
front of me he pushed it off his desk and hoped that it would smash when it
hit the floor. It didn't break so I decided to help him out and offered to
bring it back to my department and have one of our Junior Programmers put a
new drive in it. He then yelled out in the hallway "Someone trip Bordnik!
He's got my computer and I don't want that piece of shit back.".
Good times.

I thought this topic had been chewed once or twice on this
Classic Computer Collectors mailing list, but I couldn't find
it in my archive.
I often lament that there may never be an archive of news
in the middle era between the start of Usenet news and the
birth of the Web. Deja News only goes back to about March 1995.
The <http://www.archive.org/home.html> archive appears to be
down right now, but it has a simple archive of a few years'
worth of early Usenet news. I think there's a gap of at
least ten years between its archive and Deja News. Henry Spencer
supposedly archived everything into the early 90s, but did
he save the tapes and shift them to new media in time?
<http://communication.ucsd.edu/A-News/index.html> has an
archive from May 1981 to May 1982, apparently based on his files.
I found a news story on archive.org at
<http://www.newmedianews.com/042597/ts_inetarchive.html>.
Hmm. I had to blink twice, the picture of the guy running
it looks enough like me to confuse myself. Fortunately, he
didn't look like me in other pictures. He's a net god
of sorts. He founded Thinking Machines, and later sold other
companies to AOL and Amazon. archive.org is trying to
archive all Web sites. <http://www.sflan.com/> is another
project he funded - near and dear to my heart, because I'm
typing this on a VNC window on a 4.5 mile wireless link.
According to <http://www.deja.com/help/faq.shtml>, Deja has
300 million messages, accounting for more than 500 gigabytes
of disk space. They say Usenet posts are increasing geometrically.
At least with old news, you can know there's only a finite amount.
I seem to remember that in 1983 or so, all of Usenet news was only
pumping a meg or two a day. Can anyone confirm this, or supply
any other data points along this curve? How many megs of Usenet
posts might there be in this gap between, say, 1983 and 1995?
What are the chances that someone, somewhere, has an archive of
everything from these years? I guess we only need to find one. :-)

I have 0 experience with Sun. I have a friend who really likes Sun but has a
Sun SPARC IPX?. What model does anyone here recommend I buy for just under
$2K US. I see the Sun IPXs are selling cheap on eBay so are they a low end
machine? [thats what he has right now].
I am buying this for an XMAS present - probably on eBay.
I see right now:
Sun SPARC 10,7,5, Ultra 1, and others.
Any recommendations?

I have a couple of the relevant handbooks (c. 1970) and a B-sized printset
that is marked:
DEC-8/L-HR2A-D, PDP-8/L MAINTENANCE MANUAL Volume II, 3rd printing - March 1972
I can't scan 11"x17" documents, but it's only a few dozen pages - processor
flow diagrams, logic diagrams, module placement and module schematics. I can
get it copied for you either as trade in kind or for the cost of duplicating
plus shipping.
That's all I've got for the -8/L.

Not surprising.

Only if you could wedge the line analyzer in between the 11/70 and
the remote support device on the other end (i.e., a live session). I
do happen to have a couple of HP line analyzers - the ones that use TU58-
sized tapes, not the floppy version. I can follow the traffic and, indeed,
even synthesize some. We had some home-grown software that would simulate
bisync traffic and even an SNA logon sequence. Most sophisticated.

That'd be great. No hurry.

Back to that warehouse today with all the HP stuff in it.
Found this monster 21inch monitor that looks to be an RGB Type..
The Monitor has 5 BNC connectors on the back Labeled ..
1. HD (Sync)
2. VD (Sync)
3. R
4. G
5. B
Hope to hook this up to my Commodore 128D Computer..
Before I get to excited can someone tell me if this model is standard RGB ?
Or is this some non standard type ?
Phil..

It would be arithmetically but spam raised to 20,000++ newsgroups
may have an impact.

I know from 86ish to 91 I had no problem following several groups.
then all of a sudden even one group was too much.
<What are the chances that someone, somewhere, has an archive of

You'd have to check each group. some archived, some didn't. COMP.OS.CPM
used to but I think it's long gone.
