Hi all, I know there are a few PDP enthusiasts here so I figured this was worth an ask! 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 to them. 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....
