MACTECH CD NOW INCLUDES ALL OF “DEVELOP”

Westlake Village, CA — May 9, 1997 — Xplain Corporation, the publisher of
MacTech magazine, today announced that it is now shipping a new version of
the MacTech CD including the entire history of ‘develop’, Apple’s Technical
Journal.

As one of the first CD-ROM publishers, MacTech Magazine has continually
updated it’s historical CD. The MacTech CD, Volumes 1-12 includes every
article from MacTech magazine (Nov, 1984 through May, 1997), every issue of
develop (Volumes 1-29, 1990-1997), the original Inside Macintosh, the most
complete set of FrameWorks magazine archives known, hundreds of megabytes
of source code, the best utilities from the net, developer relevant demos,
and much more.

All of the articles are in THINK Reference format. THINK Reference is one
of the most beloved developer tools ever available for Macintosh. The new
THINK Reference Viewer, version 2.5, now includes boolean searches and
other features in one of the fastest search engines around.

Starting with the May, 1997 issue, MacTech magazine delivers a special
section of ‘develop’ written by Apple engineers and reviewed by Apple
technical support that will enable develop’s high-quality technical
articles and code to reach more developers than ever before. The first
develop section is included on the CD.

“Apple is excited to be joining forces with MacTech magazine to deliver the
kind of high-quality technical information previously published in the
develop Technical Journal,” said David Krathwohl, Vice President of Apple
Developer Relations. “develop’s in-depth technical articles and vital
programming on Apple platforms and technologies, combined with MacTech’s
third-party insights, product reviews, and industry news means developers
will get even more of the high-quality technical information they have come
to expect from each publication.”

“The new CD represents some four linear feet of printed matter.” said Neil
Ticktin, Publisher of MacTech. “We’ve taken every article we could get our
hands on and put it into the best online reference tool available. The
quality of develop’s content warranted that we move it immediately onto the
CD — that’s why we moved quickly to complete this within weeks of develop
joining MacTech.”

The CD has a list price of $129. During the week of WWDC, there’s an
introductory price of only $99. Upgrades from previous versions of the CD
(other than those that receive it free) are $49.

The MacTech CD will ship at Apple’s World Wide Developer Conference on
Tuesday, May 13. This is a first look or beta version. Everyone who has
purchased the MacTech CD Volumes 1-11 since November 1, 1997 will be sent
this beta version by the last week in May — automatically and free of
charge. All recipients of the beta version (including those sent it free)
will be sent the final, fully polished version of the 1-12 CD mid-summer.
