“High resolution scans of obsolete technical manuals”

If your looking for a quality scanned technical manual in PDF format please visit
our WEB site at

www.artekmedia.com

or drop us an email at

[email protected]

and we will be happy to email you a current list of the

manuals we have available.

If you don’t see the manual you need on the list drop us a line anyway we may
still be able to point you to other sources. If you have an existing manual you
would like scanned please write for details. This can often be done very
reasonably in consideration for adding your manual to our library.

Typically the scans in our manuals are done as follows;

1)  Typed text pages are typically scanned in black and white at 300 dpi.
2)  Photo pages are typically scanned in gray scale mode at 600 dpi
3)  Schematic diagram pages are typically scanned in black and white at 600

dpi unless the original manual had colored high lighting (as is the case for
some 70’s vintage Tektronix manuals).

4) Most manuals are text searchable
5) All manuals are fully bookmarked

All data is guaranteed for life (yours or mine … which ever is shorter). If for ANY
REASON your file becomes corrupted, deleted or lost, Artek Media will replace
the file for the price of shipping, or free via FTP download.

Thanks
