These have been claimed, and two people are in line behind the first person.

Re: I finally got to see a LMI Lambda in real life...

[Guy Sotomayor Jr via cctalk]

I finally dug up the link to the CADR stuff (there’s probably some other useful 
links there as well).
http://www.unlambda.com/index.php?n=Main.Symbolics 
.

The CADR emulator and all of the microcode and OS (disk) images are in the 
download
directory.  Even if you don’t use the emulator, if you ever want to get the 
CADR running again
you’ll need the microcode and OS images.

The SAGE was the AN/FSQ-7 computer, possibly the sub-units 
had some IBM designation, although a quick scan of some 
bitsavers docs didn't turn that up.  The SAGE main system 
were built on gigantic racks covered with modules with a row 
of tubes on them.  So, no housing as we normally would 
expect.  But, I think the core memory was different, and was 
built into a housing.  I think the memory unit had few tubes 
in it, needed shielding and probably used controlled 
temperature, so a housing made more sense.


But, that unit definitely matches what the SAGE core memory 
units looked like.

Re: VT240, VT241 are graphics? what does it mean?

[Al Kossow via cctalk]

The most common serial comms line graphics protocol evolved from the Tektronix 
401x
storage scope displays, sometimes refered to as the "GS" protocol for
the escape sequence it used.

https://en.wikipedia.org/wiki/Tektronix_4010

There are tons of manuals on bitsavers about them.

Just about everyone in the graphics terminal business had to support Tek
protocol, including the company I worked for (AED).

hi
so, in a description of DEC terminals, I read "VT240 and VT241 are
graphics terminals, supporting Digital’s ReGIS graphics and Tektronix
vector graphics"

what does it mean? which kind of graphics? Can they draw lines?

I am googling for "Digital’s ReGIS graphics" and "Tektronix vector
graphics", but I have only found dead links =(

The terminals were text based, until a certain escape sequence was sent.
Then it would interpret everything as a tek command. Different escape
sequences went into regis mode which were similar, but more powerful. These
were done mostly to draw plots or other graphs at the time. I believe Regis
added bitnaps to the vector graphics (which just means drawing line by only
specifying their end points and other details).

Anyone know if these are compatible with HP 8570x cards, the kind used with
HP 8920A communications analyzers?

Neat! Can you say anything about how they came to you?

Was that part of the package, or did you already have it?

There is extensive documentation around. If you look at Linux's
lkkbd.c[1], you'll find the pinout, how to build an adaptor to use it
on a regular serial port and a pointer to some scanned PDF[2] where
the hardware and protocol is descriped in depth.
