Ben Duncan Research UK
* List updated  September 2010 - now covering over 230 manuals.
* See terms at end - please read these, before enquiring.
* If your requirement is not listed here, yet we list similar material, it may be worth enquiring.
* Includes manuals listed elsewhere on this website: ex-laboratory Test Gear is also available...
* Professionally enhanced, Xerox digital repro, bound hardcopies

UK flagThis is a UK site. Don't enquire if you are overseas, unless you are prepared/ready to wire funds in British Pounds Sterling and also aware of airmail or surface postage charges. We don't accept credit cards. We do not supply PDFs. High quality requires uneconomic scanning time, and creates huge file sizes.
We specialise in hardcopies on high-grade paper, of a quality (with greyscale imaging) that aims to facsimilize our masters - which are largely originals. 'Wide schematics' are supplied in one piece.

Miscellaneous Technical Equipment
One-off disposal of one original manual set, covers 2 models:
Xerox 5760 & Xerox 5765Production colour copy machines - includes edit-pad manual.O3

Key to abbreviations of manual types:
O = Operator manual.
S0 = Service manual, content not yet designated. Info on request.
S = Schematic only. Typically 1 or 2 sheets.
S1 = Manual has basic Service information, part of operator manual, eg. circuit diagram at least, and possibly with operational description or notes.
S2 = More information than S1 but less then S3 - sometimes no schematic or other basics, but certainly including other information (eg calibration / application / parts lists).
S3 = Manual of more comprehensive Service information (not available in many instances).
Note: Dividing manuals into these categories is necessarily subjective. In any event, these designations are not about absolute size or weight and cost, but that for any given size of manual, more complete information is given, in the opinion of those who have had to use most of the manuals. "O, S" indicates that both manuals are separate entities, and available as such.
FOM = manuals for equipment over 12 years old, which are still available From the Original Maker - some for purchase, others downloadable from website that can be found by searching either for the maker's original name, or any later name (placed in brackets if known).

Maker Abbreviations & Helpful Information:
Dana Inc. (CA, USA) - were taken over by RACAL (Ltd, UK), hence latterly Racal-Dana.
HiVolt, Hunting, Hunting-HiVolt, Miles, Miles Hivolt, Wallis, and Wallis-Hivolt are all related.
HP = Hewlett-Packard. Today: Agilent.
Tek = Tektronix.
RS = RS Components (rebranded equipment).
= maker unknown, but was a well known UK defence contractor.

Xerox 5760 & Xerox 5765Production colour copy machines - includes edit-pad manual.O3

Key to abbreviations and symbols:
O = Operator manual.
S0 = Service manual, content not yet designated. Info on request.
S = Schematic only. Typically 1 or 2 sheets.
S1 = Manual has basic Service information, part of operator manual, eg. circuit diagram at least, and possibly with operational description or notes.
S2 = More information than S1 but less then S3 - sometimes no schematic or other basics, but certainly including other information (eg calibration / application / parts lists)
S3 = Manual of more comprehensive Service information (not available in many instances).
Note: Dividing manuals into these categories is necessarily subjective. In any event, these designations are not about absolute size or weight and cost, but that for any given size of manual, more complete information is given, in the opinion of those who have had to use most of the manuals. "O, S" indicates that both manuals are separate entities, and available as such.
HP = Hewlett-Packard.
Tek = Tektronix.
= maker unknown, but was a well known UK defence contractor.
FOM = manuals for equipment over 12 years old, which are still available From the Original Maker - some for purchase, others downloadable from website that can be found by searching either for the maker's original name, or any later name (placed in brackets if known).

Prices do vary widely, depending on size, need for any fold-out (A3) pages, whether the supplied items are original or high grade electronic reproductions (with greyscale for 'as good as original' photo reproduction), whether colour pages are involved, binding (size) requirements, shipping weight, worldwide destination, etc. So please enquire.
space
For example, if desired, it is sometimes possible to usefully economise on postage (shipping weight) and also the item cost, by making a miniaturised 70%+70% side-by-side version, using our greyscale capabilities. (ie 2xA4 sides copied onto one side of A4, etc). And by double-siding - although we prefer normally to enhance over existing manuals by supplying single-sided pagination, as this permits any two pages to be readily compared, as is needed in real use. If desired, user can then re-enlarge locally.
