Interesting article about the 40th anniversary of
the progenitor of many modern operating systems.
It even mentions our very own Al Kossow,
"One holy grail that eluded us for a long time
was the first edition of Unix in any form,
electronic or otherwise. Then, in 2006, Al Kossow
Museum, in Mountain View, Calif., unearthed a
printed study of Unix dated 1972, which not only
covered the internal workings of Unix but also
included a complete assembly listing of the
kernel, the main component of this operating
system. This was an amazing find?like discovering
an old Ford Model T collecting dust in a corner
of a barn. But we didn't just want to admire the
chrome work from afar. We wanted to see the thing run again."
I love the picture of the very first man page.

As I mnentioend the other night, I've added the parallel printer port to
that TD1100 viewdata terminal. The output is a DA15 socket, and in fact
the hardest part of adding the port was cutting the back panel of the
unit ot allow the conenctor to come through. I had to remove the back
panel entirely from the PCB, which invovled desoldering the line wires
and the mains wiring....
Anyway. I then had to make a cable from the DA15 to a 36 pin Microribbon
conenctor to conenct ot a Cnetronics-interfaced printer. As I mentioend,
I'd gueessed as to what the signals were, so I sued those guesses for the
Connected the unit to an old Epson FX80+ and pressed the 'print' key on
the terminal. It printed. Some garbage, some readable text. I then
rememebred the pritner setup screen (type 'P#' at the dialer screen) and
found it was set to 'teletext compatible' -- i.e. it would handle the
various teletxt/viewdata controll codes and graphics. I reset it to
'ASCII text' and tried again. This time it printed correctly -- almsot.
It was double-spacign the lines.
I then realsied that the pritner had previously been used with a BBC
micro, a machine that, by default, sends only a <CR> as a newline.
There's a DIP swithc in most old Epsons to cater for this, it foces the
AutoFeedXT line on the inteface conenctor low. Only problem was, I didn't
haev the printer manaul.
Oh well, I just took it apart and traced the conenctions from the
AutoFeedXT pin through the filter resistor to a DRIP swithc. Turnrf it
off (so it no longer asserted the AutoFeedXT signal) and put the pritner
together. This time it worked fine. My gueses on the printer port signals
had probed to be correct.
In case anyoen else wants to do it, here's the wirelist (and colours) of
the cable I made :

Does anyone here have a surplus of GPIB, HPIB or IEEE488 cables (they're
all the same thing) with metric threads? (the thumbscrews will probably
be black -- the silver ones are AIUI usually some SAE thread type or other).
I'm after a couple of the short 1-2ft "instrument to instrument" cables,
a 1-metre (to replace a nasty little knockoff cable which has
excessively long thumbscrews) and a 2-metre (to replace a buggered up

Does anyone know how to get in touch with Vince Briel these days? I've
tried e-mail to no avail and his website is a closed loop.
If you are in contact with him please pass along that I'd like to speak

LOL. I have always wondered where all the nice colorful British
