Several changes people have been asking about... here's the status....
1) The classiccmp mailing list archives at www.classiccmp.org are now
reworked and up to date. We are still using hypermail which takes the
mailing list traffic and automagically creates the website, organized by
year, month, thread, etc. etc. A background process is *STILL* running to
populate the rest of year 1999 (other years, including 2000, are already
done) but it should be done in an hour or two perhaps (theres a LOT of mail
to process in portions of that year). There is a month or two missing, but
those months are actually missing from the raw datafiles. I assume that the
list was not functioning during those times (before [and perhaps while] it
was being moved to my servers).
2) The hypermail task has been set up as a cron job to keep the mailing list
archives at www.classiccmp.org up to date without operator intervention.
Because the mailing list is hosted by a server sitting right next to the
classiccmp webserver, updates to the archive will be especially fast.
3) Previously, digest subscribers could get multiple digests per day if the
size of the digest was large (ie. it could be split into multiple emails if
the size went over a threshold). Due to popular request, that is no longer
the case. The digest will now send only one email per day to digest
subscribers no matter what the size.
4) Several people have asked - I don't have their email addresses here... so
once again - publicly, to subscribe or unsubscribe send an email to
majordomo(a)classiccmp.org. Any list traffic should go to
classiccmp(a)classiccmp.org. When subscribing you tell it which list you want
to subscribe to, either the normal list or the digest list.
Hope this gets everything in order.
Once again, I will gladly host any website, ftpsite, mailinglist, etc. that
has to do with classic computers at no charge - unlimited traffic, unlimited
storage, no fees of any kind. I am currently connected to 5 major backbones
via 100mb ethernet (and offer local dialup in over 152 US cities [shameless
plug]), so the transfer speeds should be acceptable. The only thing I ask is
that if the disk storage requirements are unusually large (say, greater than
10gb) that you buy your own hard drive and ship it to me. I'll mount it in
one of our servers and the drive will still belong to you and be dedicated
to your use only. If you decide to move, you get the drive back of course.
I'll do this for free, I feel it's something I can give back to the folks on
the list for all the endless advice I've gotten out of it. Ok, if a few
RK05's and 7900A disc drives show up anonymously, I won't complain either
<grin, just kidding>.
It would be nice if we could get a lot of subsites under the
www.classiccmp.org site, sort of like a portal. At the very least we need
some links to classiccmp sites there. Anyone care to throw together a main
page for this (I'm not an html person, and our webdevelopment staff is
working overtime already)? Then all the subsites that folks host on my
server could be at www.classiccmp.org/mydecstuff and
www.classiccmp.org/hprules for example. Of course, if you want your own
domain name that's fine too.

Univerter/Qniverter? Depending on what the docs say, would the Q-bus end
be similar to what DEC used to connect BA-11N or BA-23 boxes together?
It does kinda matter which way you are going (i.e., Unibus or Q-bus CPU)...
mostly because the Unibus is 18-bit and the Q-bus is 18 or 22 bit (or 16 ;-)
with completely different ideas about how to map space (which matters at
the driver level, not the hardware level).
We looked into such products at work, but we decided that the extra effort
on the driver did not pay for saving a development box.

To rescue from oblivion, yes. To put to immediate use, no. I have two
11/750s and wouldn't mind spares, but space/cash is too tight for such an
optional set of boards. I haven't even fired one up since I moved it to
the Quonset hut. It sits, temporarily unloved, until I can wire a 30A
Hubble receptacle for it.

No experience with this device, but you could try this:
Remove the HD and attached it as the second drive in an
old bootable PC that already has one MFM drive. You'll
need to get the drive parameters for the drive entered
into the CMOS; I think I used to use SpeedStor (?) for
that. Other utilities exist.
Then, assuming this datascope doesn't turn out to be an embedded DOS
machine (and thus the drive formatted as FAT12), use DEBUG under DOS
to load the boot sectors, then write to a .BIN file and set aside.
Load the partition table (assuming it has one) and save it. Do a quick-
n-dirty disassembly of the boot code to see where it runs off to (that
is what it loads from the drive), and if it's loading less than 64k,
you should be able to do this easily in DEBUG.
If it's loading more than 64k, you could just write a quick-n-dirty
program using your favorite language (unless that's COBOL!) to read
the datascope code in and store it in a binary file.
However, as I said above, you may find this machine is an embedded
DOS machine, and the drive may already be readable, file by file.
I've been fascinated by micro-computer monitors
for years. Possibly because my original Atari ST
had such a convoluted 13pin
As a result I've tended to grab any monitor
that didn't have a vanilla
or plain 9pin or 15pin connector. Ditto when it comes to video cards.
So the NEC series of multi-sync and other monitors with additional
switches have been high on my collectables.
The Amiga newsgroup is always full of queries regarding which
Nec works with it (3C ?}. Similiarly each of the older platform
newsgroups have the same questions.
While I know Tony Duell and others have posted the video
requirements of different systems, it has always been a
bit of a grey area for me. For example what do the dip-switch
settings on most of the configurable cards indicate ?
Some of my monitors include a Radius full-page display,
and I have a kit which supposedly allows a Mac+ to use it.
A DEC VR201 with the retactible support pole and transporting
handle which works on my DEC Rainbow.
Tatung configurable, Tandy CM5, Several Hi-resolution configurable
monitors Compaq and TVM ,Commodore 1402, Apple Color RGB
(for A2 GS),Supermac rebadged Sony GDF1950, and Magnavoxes
However, I have yet to see a good FAQ regarding these monitors.
There seems to be more info on the fixed freq. and sync on green
and I have book from MS Press on IBM CGA thru VGA monitors but
little on their configuration and platform-specific features.
Possibly each mfg. issued a booklet with their monitors and the
market wasn't big enough for a book. An area to explore.
My system includes a JDH Videomate external box which is a
TV to VGA converter and my main TV when not displaying
computer-specific info. Again , a defunct company, so no info.
I purchased an interesting system at the Timonium Hamfest last weekend. It's a
SparcStation IPX, refitted to a military case. I've put some pictures up at
<http://www.applefritter.com/temp/saic/>. It consists of the computer itself
and an expansion chassis that latches onto the bottom of the case.
Right now, I don't have the machine running. The power supply I got with it is
a LAMBDA, 24VDC, 10.5 A. I don't have a military connector, so I've been
sticking the wires onto the pins. I managed to get the system to power on.
It gives a splash screen reading "Tech-Source Inc." followed by a line I didn't
think to write down before it started having problems.
At the next spring it tells me a bit about itself:
SparcStation IPX, Keyboard Present
ROM Rev. 2.9, 64 MB memory installed, Serial #2219226
Ethernet address 8:0:20:1a:c:28, Host ID: 5721dcda
And informs be that it can't boot off the hard drive (the seller told me its
been wiped clean).
Just a few minutes ago the power supply apparently gave out. I had the machine
powered on and was copying down the above information when it seemingly powered
off and the screen started flickering on and off. I'm not at all familiar with
Sparcs, and I really don't know much about power supplies either. Does this
strike the anybody as a faulty power supply connection, or something else?
The expansion chassis needs its own power, so unless the power supply I have is
powerful enough to power both (opinions?) I'm going to need a second. I need to
get the expansion chassis up and running as it has the CD-ROM drive (along with
a second hard drive and a tape drive) in it which I need to install the
Does anybody have any suggestions regarding getting this system running? Know
where I can find some decent power supplies that will work? Ideally with the
three-prong military connectors?
Thanks for the info.

There is one that runs under UNIX.
Also the rollers for the TU58 I clean off the goo to get down to the
basic hub then use .500 od/.375 id Tygon tubing. which is a stretch
fit over the hub, add a drop of super glue and trim to width as
diameter is not critical and that material seems to hit it very close.
I've done this to maybe 8 them I still use.
hey do you have any ideas about using relays or some thing connected to a parallel or aerial port to control the power to an outlet, you know like a dimmer switch controlling motors ETC
if you have any thought or ideas I'd be glad to hear them.
Could you be referring to "Microcomputer Design" by Donald P Martin and
published by his company, Martin Research in Northbrook, Illinois? It has a
black cover with a photograph on the front of integrated circuits lit from
below. A large format squarish paperback about an inch thick. I don't see
an ISBN listed, but the Library of Congress Catalog number is given as
It is full of practical application advice about the 8008, and includes
stuff about the "new" 8080 too. The last chapter describes various "minimal
microcomputer" circuits and Martin's own product line of Modular Micros such
as the MIKE models 3 and 4.
I have the 2nd edition published in 1976, and it is a treasure.
