I read in the PDP-7 reference manual that Precision CRT Display Type 30
and Precision Incremental Display Type 340 are the typical displays used
with the PDP-7, but aren't standard equipment. I read about the
Graphics-II scope. Was it the only display? I read it was used as a
second terminal and that it would pause per display full with a button
I assume this second terminal's keyboard was TTY model 33 or similar
since it was the standard equipment. Does anyone know?
Do you know if the PDP-7 or early edition Unixes have pen support for
that Graphics-II or similar displays?
Clem has written that the PDP-7 had a disk from a PDP-9. Where is this
The ~1971 draft "The UNIX Time-Sharing System" says first version runs
on PDP-9 also.
But I cannot find any other reference of running on PDP-9 at all. Was
That draft calls the PDP-7 version the "first edition" but later the
PDP-11/20 is called the "first edition". When did the naming of first
edition get defined to not include the PDP-7 version? Or is it because
the early "0th" version was never released/shared outside?
mentions an "interim machine" and a "PDP-11 that had PDP-10 memory
management, KS-1." What is this interim machine? Is this a PDP-11
without a disk (for a few months?) What is this PDP-11
and KS-1? Maybe this is the PDP-11/20 with KS-11?
Do we know what hardware was supported for the early editions? We don't
have all the kernel code and from a quick look from what is available I
didn't see specific hardware references.
The later ~1974 "The UNIX Time-Sharing System" paper does mention some
hardware at that time on the PDP-11/45 like a 201 dataset interface and
a Tektronix 611 storage-tube display on a satellite PDP-11/20.
When did a CRT with keyboard terminal like DEC vt01 (with Tektronix 611
CRT display), LS ADM-3, Hazeltine 2000, VT01A display with keyboard
(what keyboard?) get supported? Any code to help find this? (The
https://www.bell-labs.com/usr/dmr/www/picture.html does mention the
VT01A plys keyboard).
