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....
