Aztec C - a programming language for a variety of platforms including MS-DOS,
Apple II DOS 3.3 and PRoDOS, Commodore 64, Macintosh and Amiga.
Software that is no longer current, but is still of interest.
The purpose of this website is to provide a free internet archive for
various versions of the now-discontinued Aztec C Compiler for older now-obsolete platforms,
and to provide related compiler documentation and Aztec C source code and samples that support
the Fair Use of these discontinued compilers
for educational purposes by programmers, researchers and enthusiasts.
If the aforestated is not your intended use, you may not download from this website.
Please email me (Bill Buckels) at firstname.lastname@example.org if you
can provide me with Aztec C Compilers, Documentation and Examples other than what is listed
on this website.
Emulators for these older now-obsolete
platforms have become popular with enthusiasts and hobbyists,
and most emulators are free or almost free. As far as I know, no commercial market exists
for programs or development environments that run on these older now-obsolete platforms.
However the native Aztec C Compilers for these platforms are still quite as usable as they ever were
on their respective native platforms, and the MS-DOS Aztec
C cross-development compilers for
these platforms work under Windows XP and in other operating systems that provide support for
MS-DOS either directly or through the use of MS-DOS emulators (like Linux).
This means that a C programmer-enthusiast can create
programs in an emulator or in the MS-DOS or Windows environment then run them on
an emulator or transfer
them to a real (but obsolete) target computer using a serial cable, flash memory,
or some other means.

Manx Software Systems of Shrewsbury, New Jersey, produced C compilers beginning in the 1980s
targeted at professional developers for a variety of platforms up to and including PC's and
Manx Software Systems was started by Harry Suckow, with partners Thomas Fenwick, and James
Goodnow II, the two principle developers. They were all working together at another company at
the time. Harry had started several companies of his own anticipating the impending growth of the
PC market, with each company specializing in different kinds of software. A demand came for
compilers first and he disengaged himself from the other companies to pursue Manx and Aztec C.
Harry took care of the business side, Fenwick specialized in front-end compiler development, and
Goodnow specialized in back-end compiler development. Another developer, Chris Macey, worked with
them for awhile on 80XX development and in other areas.
The name "Manx" was selected from a list of cats for no particular reason except that the name
Harry wanted to use was taken by one of his other start-up companies.
One of the main reasons for Aztec C's early success was the floating point support for the Z80
compiler which was extended to the Apple II shortly after. Harry insisted on adding floating
During the move to ANSI C in 1989, Robert Sherry who was with Manx at the time and interested in
the minutiae of standards represented them on the ANSI committee but left shortly after.
By this time Microsoft had targeted competitors for their C compiler and Aztec C was being
pushed-out of the general IBM-PC compiler market, followed by competition with Apple's MPW C on
the MacIntosh side and Lattice C on the Amiga after SAS bought them.
By the early 1990s Thomas Fenwick had left to work for Microsoft, and James Goodnow worked on
Aztec C occasionally but was pursuing other projects outside the company and eventually left the
company altogether. Harry employed about 20 people at that time. Chris Macey returned as a
consultant but eventually left to become chief scientist for another company. Mike Spille joined
Manx as a developer along with the late Jeff Davis (embedded systems).
Throughout the 1990s they continued to make their Aztec C. As their market share dropped, they
tried to make the move to specializing in embedded systems development, but it was too late.
They disappeared a few years back following the loss of market presence of some of their target
platforms (various 6502 machines, Atari and Amiga 68xxx, etc.).
In the end, Jeff Davis and Mike Spille helped Harry Suckow keep the company going
before Harry finally closed it. Harry Suckow is still the Copyright holder for Aztec C.
Many professional developers used Aztec C compilers from Manx Software Systems before they
vanished from the planet.Despite the fact that these compilers are no longer of any commercial
value, if those of us who still enjoy the art of programming in C on these old platforms can
share this enjoyment by making Aztec C available to others, the excellence of Aztec C
will live on.

How This Website Came To Be
I first got the idea for the Aztec C website
back in 2007 as a result of rediscovering a some of my old Apple II programs that
had been written in Aztec C. This in turn was as a result of research that
I did for my ClipShop Program rewrite
which handles among other things conversion to Apple II Graphics.
One thing led to another with many detours along the way, and when I
decided to put my old Apple II programs online, I wanted
to offer the source
code as well. That part is a little complicated, but I realized that
I would need the permission of Aztec C's Copyright holder to provide
the compiler that I had used to do these if the source code
was to be of any use.
The Aztec C website went-up cautiously at first and began to grow as
my adventure in search of Aztec C continued. When I finally found
Harry Suckow who started Aztec C in the first place and who, as the
Copyright holder gave permission for this site, I had already accumulated
a modestly large archive of compilers from many sources.
Aztec C was a long time ago for Harry and his former partners, Thomas Fenwick
and James Goodnow II. In the end my discovery for compiler source code and
manuals from the orginal authors turned-out to be unsuccessful for
many reasons and Harry eventually withdrew from the process.
By that time (mid 2008) the Aztec C website had become the Aztec C Museum
and with the help of ongoing contributions from former users and other
archives had grown and continues to grow.
I still remain cautiously optimistic that eventually the orginal authors
will come forward with some of what was lost to this crazy software
business that gave us Aztec C in the first place.
In the meantime I am grateful for what we still have from those Olde Tymes.
