PDP-8 Document Viewing Help
Most of the documents are in TIFF format or PDF format. The TIFF files are
multipage and normally use group 4 compression. This format
is an image format you can't search or copy text from the documents. The PDF
files are in the Adobe portable document format. This format can either be
text or images.
Most of the documents are images since they were scanned from paper without
trying to convert using optical character recognition (OCR). OCR tends to
need a lot of hand editing to correct errors.
Most of the files from the site ftp://ftp.dbit.com are ASCII text files.
They have the extension .doc but are not Word documents. They can be
viewed with most any editor or word processor.
For viewing the TIFF files the windows TIFF
viewer looks better on screen than the Acrobat reader if the TIFF viewer
scale to gray option is selected. The TIFF files are also somewhat
smaller than the PDF files.
For printing the PDF may keep the text size closer to the original document.
Most of the viewer programs have an option to scale the documents to fit the
page when printing. If the documents doesn't fit well on the page turn this
option on. For acrobat if you have this option off when printing pages which
are close to your paper size they will look better with larger margins.
This option is normally on the print menu or the print options menu.
- To view portable document files with extension PDF use the
Adobe PDF reader from
or Text only
download page. This software is available for many different operating systems.
- To view TIFF files with extension tif or tiff:
One package that can do this under Windows 95 or later is the free "Imaging for Windows". Later versions of Windows 95/98/NT come with
direct link to the download page. Also the
AlternaTIFF browser plugin for viewing TIFF files is available.
Paint Shop Pro 5 from JASC Software can also
load these documents. A multiple page document is read with each page coming
up in a separate Paint Shop Pro window. While not optimal, this works, and
Paint Shop Pro is a great application.
- Are you a Mac user? If so, here's a link to
Graphic Converter, a utility that will let you read these TIFF files, and
optionally convert them to other formats, including PDF. This link was provided
by Al Kossow, email@example.com.
