I know there are a few PDP enthusiasts here so I figured this was worth
I'm looking for any software, manuals, photos of hardware - anything
really - that relates to the Jerrold Communications / General Instrument
analog cable TV headend equipment.
Many of their headend "addressable controllers" were built around DEC
hardware -- the AH series units used a PDP-11, the Terminal Configurator
ran on a PC, the ACC-4000 ran on a DEC Prioris server running SCO UNIX.
Things I'm looking for especially --
- The software from the ACC-4000 Addressable Controller (Prioris
based), AI-0/AI-O or AH-4/AH-4E (PDP-11/73 based) controllers, or
Terminal Configurator (PC based).
- Backup tapes from a running system (may be TK50, or DAT/DDS)
- Terminal Configurator, Message Editor (ME-1000) or "OSD Edit" software
- Any documentation
- Photos, or other details of the I/O cards (either the PC one -
which may have been called ANIC - or the SCX11, SCX11E, SCX11M or SRT11
cards used in the PDP systems).
I'm trying to build an analog cable TV headend from scratch, as a bit of
a preservation and "to see if I can" project.
So far I've managed to modulate a couple of channels and get a cable box
to tune to them, but my two boxes have different frequency maps, and I
need some way of sending an "Input Frequency Map" or channel name table
I'm hoping that someone might have inherited a bunch of backup tapes,
hardware or media from a cable TV company who was migrating to digital....
Going through my stuff I found a Matrox QRGB 6/64-4 card which seems to
be a 512x512x16 color video array for Q bus systems.
Did any software ever support this thing, and does anyone want to trade
it for a bean of some sort?
During lockdown I was having some fun redrawing old DEC manual covers
with Inkscape, specifically terminal and printer manuals from the late
1970s. I've attached a montage of four that I printed out so I could
stick it on the wall. I'm aware I may be the only person, even here,
who finds them attractively simple and coloured in such a definably
Some of these designs were used on several manuals, but I'd like to
know if you know of any other designs that follow this pattern that I
could add to the collection? The VT102 User Guide has different
colours, so it looks out of place. A copy of the LA34 User Guide is
winging its way to me as we speak.
For an infinite number of bonus points, does anyone have any clue who
might have designed these?
I have a PDP 11/05 that I’ve been restoring slowly over the last few years. I’m to the point now where I’d like to get a paper tape reader attached to it. The only reader I can find in my junk is a Bower Associates BAI Data Products model 1230 punch. I’ve put a picture of it here for the curious:
I can’t find any documentation online about this machine. I’m wondering if anyone else has any ideas, or might know anything about this. It’s going to need some TLC to bring it to life, and some documentation would certainly be nice.
This particular unit was used by the Atmospheric Environment Service, Department of the Environment of Canada (according to a label on the back). It looks to be complete, except the punch bin is missing (not a big deal).
Anyway, I thought I’d throw it out there in case anyone happens to know anything about this, before I tear in to it.
I had a dream ; that someone makes a small telnet to chatgpt gateway (using azure chatgpt API possibly ?) So that we could telnet our retro devices to the hype of the year, and get chtgpt answers in our TRS80, PDP and such.
