I have a client trying to sell me approx 6 working RL02 drives, a
variety of Q-bus items, and a Digidata tape drive.
I do not want to sit on the drives, if you have any interest please
contact me off list. I need to let them know by Friday afternoon.
Drives can be palletized and shipped or picked up in the midwest.
Thanks Paul

I have a 3000/37 that I run on occasion. I did have a /42 before my big move last year. I didn't have enough room so, I had to let it go.
Both machines ran MPE/V which I got from HP during their great Y2K upgrade/giveaway.
I'd really like to find a machine that runs MPE/IX. I see them on Ebay occasionally but, they are either too much money on on the other side of the country.
See yas, SteveRob

Subject: HP-3000 (was: HP HP-2117F on ebay)
Speaking of old HP minis, does anyone have an HP-3000 in their
collection? Not the newer ones, but the ones from the mid to late
70s.
I have MPE/V that ran on my /42. Is that what you're looking for?

CHM has a Series II, Series III and a model 44. Finding MPE that will
run on these is the problem. There has been talk of a classic 3000
simulator for a while, but I've not been able to find early enough
software releases for the machines with good hardware documentation.
The 4x series machines have a console processor is a HP proprietary
microcontroller unlike those that came out of Fort Collins.
In the early '80s at ADP Network Services (old timesharing service), we
connected a couple of IBM and compatible mainframes (IBM 4381, Amdahl
470) to our packet switching network. It took our systems guys a bit of
work, but indeed, they did connect the 3725 to a PDP-8... and from that,
to the rest of the packet switching network. (The network was originally
designed and optimized for PDP-10's, which coexisted with the blue
boxes.) The IBM side ran under CICS. As I recall we eventually needed 4
PDP-8's (as network bridges) to carry all of the traffic from the 2 IBM
boxes-- supporting 400 or 500 simultaneous users. Ah, the old days...

Except that (if memory serves) this kind of coprocessing communications
aggregator would be able to pass more data than the P/370 has I/O bandwidth.
Anyway, I've seen many P/390 installations that are bigger than a PDP-8.

Exactly.
I am really only a buyer and have only ever
sold one item. I currently have a rating of 99
on there. Thats 101 positives and 2 negatives.
The first negative was added accidentally by
a buyer, long before the option to mutually
agree to remove feedback was added, and he
sent me an email to apologise for his mistake.
The 2nd one is, however, valid. I won too many
items at the same time and relied heavily on
my emails to check what was paid for etc.
I missed an item and didn't realise until it
was far too late (I had a seperate email
account specifically for it back then and only
checked it every 2-3 weeks).
You will always find someone with negative
feedback. If you didn't, then I'd be rather
suspicious - especially if they have more than
1,000 positives.

I'm looking for AAA-sized rechargeable batteries. Good capacity would
be nice, but the main thing I'm looking for is that it should be able to
supply a fairly high peaky current draw.
Any suggestions?

Listowners perogative to ask a question that is only halfway on topic.... ;)
I figure some people here may have some good suggestions - offlist please.
There is a SpamAssassin machine(s) filtering spam being sent to the list
that sits in front of the classiccmp server (we're also making use of Pyzor,
Razor, milter-ahead, and clamav). It's been doing a wonderful job, such that
most spam is kept out of the moderators faces. However, over the past few
months I've noticed that more and more is getting through (not to the list,
but to the moderators eyes who have to kill it all manually). Same goes for
many of my customers.
What concerns me is that 99% of the new spam making it through is vaguely
sensible english phrases (apparently automatically pulled from online books,
or from usenet post archives, etc.). If there was also an advertisement
text, Spamassassin could catch that. However, the text is all just english
phrases (I've noted them to be targeted phrases, like having to do with
computers, sometimes old ones) BUT... the advertisement is a graphic
attachment. Since SpamAssassin can't do OCR on the small gif or jpg
attachment that says "buy viagra here"... I am not sure what to do about
this. It comes from all over, not just a few servers, etc.
Before you say "just kill all emails with graphic attachments"... keep in
mind that these spamassassin machines do their job for thousands of domains
that I host, not just classiccmp.org. So just killing all emails with
graphic attachments is simply not an option. If anyone can give me a few
ideas that will work well for ISP/hosting-class environments, I'd love to
hear it. Off-list please! Thanks in advance for any advice.

Hi Eric,
The Computer History Museum recently acquired a SDS 910, 920, and
accepted donation of a SDS 930 (940 predecessor) from History San Jose.
See pics at

http://www.flickr.com/photos/lee_courtney/sets/72157594391722530/.
If your Dad is in the Bay Area would be happy to give him a tour at the
Museum. Just had one of the original SDS/XDS HW designers come thru over
Thanksgiving.
Cheers,

Jay, thanks for the rundown on this system. The closest I've ever come to an HP mini was when I saw a 6' rack that with one at the local university surplus 'store'. Unfortunately, they were only relocating the system to another part of campus, so would not sell it. Frankly, I was interested in it *because* it was fully racked with drives, etc., and had an ASR-33 with it. It was clearly a whole system. (BTW, I did convince them to sell me the ASR-33!)
But, this business with ebay is really starting to annoy me, since it's nearly impossible to find a whole system, these days. Everybody is just parting out the bits and pieces, like that whole series of the '11/40' unibus boards that end this evening. I'm becoming a bit disheartened with the 'chop shop' mentality. And, that's trouble for someone that is ignorant of what key components may or may not be required to get a system functional again. It sure is easier to 'shop' for parts that when you already have knowledge of the system in question.
On the other hand, I think that's what I like about this 'hobby'... the exploration and (re)discovery of what these old systems really were/are and how they are operated. I admit that it isn't just the operation of my little collection of qbus systems (PDP's and VAXen) that is the end all, but rather the discovery, in my case (versus re-discovery), of how these system were constructed, configured and operated. Truthfully, this is the fun part for me.
So, thanks to you, Jay -- and others on the list -- for keeping the fires burning, and helping us 'ameteurs' out from time to time.

I'm playing around with a VR241 - the colour monitor bit of the VT241 -
and trying to make it work as a standard video monitor. It has two pairs
of RGB+sync inputs, and an "INT/EXT" (presumably sync) toggle switch.
I have been unable to find any specifications for this monitor online. I
don't think the Monitor Database one is correct - if it is, I'm doing
something wrong.
Is it possible to hook this thing up to a PC? Is there anything I need
to bear in mind when configuring X?
TIA,
-Tore
