WESTLAKE VILLAGE, CA — AUGUST 4, 1997 — Xplain Corporation, the
publisher of MacTech(r) magazine, today announced that it will be shipping
the release version of the MacTech CD-ROM, Volumes 1-12, which includes the
entire history of develop, Apple’s awarding winning technical journal.

As one of the first CD-ROM publishers, MacTech Magazine has continually
updated its historical CD with an extensive library of reference material,
hundreds of megabytes of source code, special offers with developer demos,
and much more.

The MacTech CD, Volumes 1-12, includes every article from MacTech magazine
(November, 1984 through May, 1997). It has the entire history of develop
(Volumes 1-29, 1990-1997). The CD also has the original Inside Macintosh,
and the most complete set of Frameworks archives known (the publication of
the late Software Frameworks Association).

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 also included on the CD.

MacTech’s flexible THINK Reference Viewer (2.5b2) gives the user faster and
more searching capability. 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. The new search capabilities are
a valuable addition to the CD by making it easier to find the references
you need. All of the articles are in THINK Reference format

The CD has a list price of $129. There’s an introductory price of only $99
through August 31, 1997 — act now!
