This is a terminal customized for use with Xerox centralized
production printers. 8700, 9700, late 1970's to early 1980's as I
recall. I have two of these terminals on-hand, one still has the
Xerox logo plate, the other does not. Both are operational though.
The terminal was set up with custom commands apparently, so that
pressing a particular key would send an entire command (This may have
been handled on the controller side though). Working from memory
here, as it's been a few years since we decommissioned our 9700. Our
current printer, a Xerox 4090, has a similiar setup, with a newer LINK
brand ADM3A terminal.
The "SAMPLE COPY" button would send the full command to request a
sample copy of the output. STOP halted the printer; CONTINUE
continued printing the current job. STATUS would give information on
jobs in the print queue (accounting ID, pages printed, total pages
spooled to the print controller, etc). CLEAR would clear the entire
input line. RUBOUT, I never used but I think it wipes out the
currently selected word. To my knowledge, there was user operable no
cursor positioning available of any kind. Any typos had to be
remedied with either a change command (c/error/correction) or by
retyping the entire line. The print controller was a PDP11/34 (or
/34A), with various custom option cards and a bus expansion box
installed. Removable-platter hard disk by CDC; StorageTek vacuum
chamber 9-track tape drive. 800/1600/3200 bpi base, 6250 was an
option.
If anyone would like more info, I have complete service manuals on
the 9700 printer (and a few parts) available.
Also, DigiBarn has a page on the 9700 which is a bit dated. It also
shows a different setup than what I ran. Ours had a full-height Xerox
controller, as opposed to the PERQ T2 based controller.
