The THEOS Operating System
"For the developers and end-users using THEOS based applications the
system benefits are readily apparent. But let's take a look under the hood
and see what makes THEOS operating system and development language so
unique and long-lived."
The Benefits of the THEOS Operating System
The following is an extensive listing of the features and functions why developers choose the THEOS
operating system as the platform for their vertical business applications. When Tim Williams began
developing compilers, development tools and operating systems for the fledgling personal computers in
the late '70s, he wanted a multiuser system that could be used by businessmen without the need for an
expensive IT infrastructure. He made his products easy to use for development which translated into easy
to use applications for end-users that did not overwhelm the small business. He wanted his systems to be
robust and reliable, not fragile and temperamental. He wrote a development platform that kept its eye on
the business world, not on entertainment. That remains true today.
- Robust -- servers are reported to reliably continue running for many months without
restart or repair and many years without replacement. In the last two months we have helped
end-users who were still running their businesses on Intel 286 machines from circa 1990.
"Program Fault" and "Fatal Error" are endangered species in THEOS-based applications.
- Virus immune -- no e-mail virus, no web-based virus. We rely on Intel chip security rather than
software security. This means we cannot be all things to all people, but it also means that THEOS
O/S cannot be hacked through its data segments as are other systems.
- No games -- just productivity. No solitaire, no hearts, no pinball, no backgammon, no
minesweeper, no spades. End-users can install a THEOS application on serial terminals or low-end
PCs so that their employees do not spend all day on the Internet or playing games. At the
same time, selected individuals can use Windows machines if their work requires the Internet,
Word, Excel or a non-THEOS Windows application. Switching between THEOS and Windows is
just one keystroke on the same workstation.
- Small foot print. Single CD-ROM installation. Requires as little as 100 MB disk space, can run in
as little as 16 MB RAM. Hardware is still a cost factor to the small businessman, particularly in
access control, retail and factory floor installations.
- Low cost of maintenance -- built-in ability for VAR to connect and upgrade
using modem or Internet. All but major version releases are downloadable by VARs from our Web
Site. THEOS is backward compatible so upgrades to the O/S need not require any application
coding to take advantage of the new O/S features.
- Low total cost of ownership -- no need for full-time IT or systems manager. VAR can easily
monitor end-user sites on annual or semiannual basis. Compare this with the typical NT
installation. Many VARs monitor their customers online through a "peek" process. This also
facilitates training new employees and refresher courses for others -- a welcome, low cost
revenue source to the VARs.
- Easy, consistent configuration of O/S and network servers. Printers, video drivers, sound
drivers, etc all come from THEOS in the same format rather than from various unrelated sources.
- Fast startup / shutdown -- under ten seconds startup, under five seconds shutdown.
- Fast installation -- typically under ten minutes to install and get running on new computer. VARs
can talk even non-technical end-users through the installation and configuration of a new set-up
such as a new store in a chain or a new customer located far from the developer.
- Configuration to suit the customer. Classic serial terminal multiuser configuration or a
networked PC multiuser configuration or both throughout the office, plant, warehouse, etc. -- it
is the customer's choice.
- Web-based configuration and control of server. This is the interface being used in China where
THEOS servers maintain and protect the data for a system handling 7.5 million citizens' data
while they access the system through user-friendly Web sites.
- Authentication control for O/S and VAR-developed applications -- no piracy. Many VARs
serialize their applications to the same Serial Number through which THEOS licenses the
operating system, marrying the application and the O/S for their own security.
- Easy to understand and use development language. Tim's MultiUser BASIC gets rave reviews
from developers, continuing his precept of "ease of use" into a fourth decade. The latest release
provides the structure for our VARs to develop GUI applications on top of the robust, virus-proof
foundation of all THEOS systems.
- Workstation choice of classic text-based user interface on low-cost ASCII terminals and
workstations, or graphical based user interface. No change to VAR-developed applications. You
can use both text and graphical user interface on same system. This allows the businessman to
have heads-down, text-based data entry workstations and graphical management workstations
on the same application, in the same office, running off the same server.
- Product focus directed by a small team of engineers headed by one man for more than 25
years. This is a particularly fascinating feature to the Chinese healthcare customers.
- Internet server standards. While the internals are proprietary, the servers are built on Internet
standards for data interchange. This includes such standards as SMTP, POP3, FTP, HTTP,
TFTP, SMB, ISO-9660 CD-ROM, USB, PCMCIA, PCI, etc.
