Thank you guys!
Aside from these major contributions, many other pages and resources were
merged with the Ardent Tool. You should always find the name of the original
author either directly on the page in question, next to the link that leads to
it, and/or in the global changelog below.
If you are one of the original authors and you can't find your name anywhere,
want to request some edits or content removal, please don't hesitate to contact
us.
All direct email links present on these pages were either removed or
replaced by an email form to avoid spam and email address harvesting. If you
want to contact one of the original authors, please use the link that points to
their website and look for contact information there, or contact us and we will
point you in the right direction (if possible).
The website also contains various documents - such as technical references,
brochures, patents, articles from various computer magazines, etc. Authors of
these materials are either named explicitly on the page from where they can be
accessed and/or are named directly in the material itself.
New Content
The MAD Edition also features a large amount of new content created by
me - Tomáš Slavotínek. This includes technical explanations, tutorials, various
text notes, board outlines (TS signature), schematics and other illustrations,
pinouts, reverse-engineering and measurement results, hardware modifications,
and more.
Many of the pre-existing pages from Louis Ohland and other authors were
modified, moved, merged, or separated. Page changes range from simple typo
corrections to complete overhauls. Some of the illustrations, tables, and
other content were completely reworked. The main index and most sub-index pages
were redesigned from a scratch to make navigation easier.
Despite all these changes we are trying to keep all existing external links
alive by adding redirects and/or rewrite rules where needed. This includes
links pointed to the original location of the Ardent Tool on
Kevin Bowling's server.
