This article is from the MachTen & CodeBuilder FAQ, by Jaime Julca firstname.lastname@example.org with numerous contributions by others.
Tenon's goal was to "unlock" the processing power of personal computers and
put them on an equal footing with workstations, minis, and mainframes.
On one hand, MachTen brings UNIX applications and technology to the
Macintosh desktop; on the other hand, it provides a vehicle for Macintosh
users to access those larger functional capabilities and communications
protocols that are fundamentally developed by the workstation community.
These industry standard tools can be brought to the desktop where Macintosh
applications are able to take advantage of them. It is a dual-directional
MachTen makes client/server computing available for everyone by lowering the
price point of this capability by an order of magnitude. When Apple built
the Macintosh, they called it a computer for "the rest of us". MachTen is
UNIX for "the rest of us".
