Hello Sir,
I have this printer with Parallel Centronics connection.
How do I print something using modern pc?
Thanks for information on power connection, great help.
Thanks

Dear Noel,
Thank you very much for making the M9301-YA.mac file publicly available (https://www.classiccmp.org/pipermail/cctalk/2015-April/006241.html), but I can't download it...
When I try to download it, I get the message: "You don't have permission to access /~jnc/tech/pdp11/M9301-YA.mac on this server."
Could you please email me the M9301-YA.mac file archive?
With best wishes

George Goble passed away

From Wikipedia:
https://en.wikipedia.org/wiki/George_H._Goble
George Harry Goble (December 11, 1952 – March 18, 2026) was an
American scientist and academic, who was a staff member at the Purdue
University Engineering Computer Network and a 1996 Ig Nobel Prize
winner.
Goble was commonly known as ghg, since he used that as a login id and
signature in digital communications from the 1970s. He received his BS
in Electrical Engineering at Purdue University.
In 1981, he wired together the backplanes of two DEC VAX-11/780
systems and made the first multi-CPU Unix computer, preceding DEC's
dual processor VAX-11/782.[1] The operating system was based on the
4.1 BSD kernel,[1]: 293 and the modifications thus eventually made it
into the 4.3 BSD Unix release.[citation needed] At the beginning of
the 4.3 BSD user manuals, Bill Joy wrote a special note of thanks to
GHG for being courageous enough to put the multi-CPU kernel into a
production environment before anyone else did.[2] (However, the
frequent crashes for a while inspired the writing of many humorous
text files by the Purdue University Electrical Engineering student
body, such as "The VAX had a Blowout", to be sung to the tune of
"London Bridge is Falling Down".) The development of the Dual-CPU Unix
system was the subject of Goble's Master's thesis.
Around this time, Goble, along with Bill Croft, also developed a
networking protocol for Unix, referred to as pnet, which was used at
Purdue at the time before being displaced by TCP/IP. Pnet allowed
remote logins, and remote execution of commands, among other
capabilities.[3]
In the late 1980s, Goble started experimenting with refrigerants, due
to increased danger and lower thermodynamic efficiency of the recently
introduced R-134a compared to the older R-12 which was being phased
out due to concerns about damage to the ozone layer, and the
incompatibility of R-134a with the lubricating oil and other materials
used in systems built for R-12. In 1987, he converted the beverage
refrigerators in the Eta Kappa Nu lounge in the basement of the Purdue
Electrical Engineering building to using a refrigerant of his own
devising. This refrigerant is now recognized as R-406A by ASHRAE and
is available commercially under the trade name AutoFrost. He later
developed another refrigerant which is compatible with R134A
lubricants, but which is superior in thermodynamic efficiency and
lower system internal pressures called GHG-X8.
In 1996, Goble was awarded the Ig Nobel Prize in Chemistry, for
preparing a barbecue for cooking in less than 5 seconds by the use of
a smoldering cigarette, charcoal and LOX (liquid oxygen).[4] This act
attracted the attention of the West Lafayette, Indiana fire
department, which warned him to never let them catch him in the
possession of LOX near a barbecue fire ever again.
Goble was also noted for driving a vehicle with the Indiana license
plate UNIX, and also GHG-1

According to legend, so it has been proven to be a fact, Apple was created
50 years ago today. The classic computing world is one reason we as members
can look back and witness the contribution Apple has played. Whether this
is a mixture of delight or sadness doesn't take away the contribution Jobs
and Wozniak played in my and others interest in keeping classic computing
alive.
Happy computing all.

Hi all,
I am looking for advice on some problems that I am observing trying to
read QIC tapes using an Archive Viper.
If you are unfamiliar with QIC tapes, tape transport is done through a
single roller that moves a plastic band in tension with the outside of
a portion of the tape on the reels. Over time, the band will break.
A long time ago, I bought a bunch of the green plastibands to use as
replacement bands. Later I bought a bunch of the clear ones. I was able
to image some tapes with the plastiband replacement but not all (but
rewind and retension works almost every time). Until today, I don't
think I ever tried the clear ones after I bought a bag.
I am preparing for a VCF and need the contents off of some of the tapes
that I have, so I got out the driver and tapes. However, I have been
unable to read anything from the them. The tape will jam up. It seems
like what is happening is that plastiband is not providing enough
tension to move the tape when reading. The tape loses tension and I see
it gather instead of moving along. Sometimes the tape feels stuck to the
posts that turn the tape to be parallel with the heads.
I also tried a clear band for the first time and the tension with that
seems too tight.
What am I doing wrong?
