TurboDOS/PC  is  a  software product that interfaces MS-DOS  machines  with  a
TurboDOS network. It runs on the IBM Personal Computer, PC-compatibles, or any
8086-family microcomputer that uses MS-DOS or PC-DOS version 1.x, 2.x, or 3.0.
TurboDOS/PC  allows the PC to become a TurboDOS network client, and to  access
the disk drives and printers belonging to the TurboDOS file and print  servers
in the network.

Each  PC  continues  to operate normally under control of  its  native  MS-DOS
operating  system  with full access to its local disks  and  other  peripheral
devices. The only effect of the TurboDOS/PC network connection is that the  PC
has access to more disk drives and printers than before.

For  disk  operations, drive letters beyond the highest local drive  refer  to
remote drives accessed via the network. Remote disks may be used exactly  like
local  ones.  All the usual file- and directory-oriented  commands  of  MS-DOS
(like  COPY, DEL, REN, DIR, CHDIR, MKDIR, and RMDIR) work on remote and  local
drives  alike. The sub-directory features of MS-DOS (versions 2.00 and  later)
are  fully supported on remote drives. MS-DOS application  programs,  overlays
and  data  files may be copied to and executed from remote disks,  except  for
packages that use copy-protection schemes to prevent this. Remote files may be
accessed by several TurboDOS and PC users simultaneously, subject to the usual
TurboDOS file-locking rules.

TurboDOS/PC allows print output to be routed either to the PC's local  printer
or  to  remote printers accessed via the network. All of  the  advanced  print
routing,  spooling,  and  print job control features  of  TurboDOS  are  fully
supported by TurboDOS/PC. Automatic print spooling allows many users to  share
one printer without interfering with one another.

In  addition  to  fully supporting the MS-DOS  environment,  TurboDOS/PC  also
includes a special program interface that gives applications direct access  to
the native file- and print-oriented functions of TurboDOS.

TurboDOS/PC works with any of the PC-compatible accessory boards that  provide
a high-speed network port (ARCnet, Ethernet, RS422/SDLC, etc.). The package is
furnished  as  several MS-DOS "COM" files that may be executed  from  a  local
disk.  Alternatively,  MS-DOS  and  TurboDOS/PC may  be  downloaded  over  the
network, using a bootstrap module provided with the TurboDOS/PC package.

Finally, every good software package deserves equally good documentation.  The
82-page  TurboDOS/PC  manual  is both tutorial  and  comprehensive,  including
separate sections intended for users, programmers, and implementors.

        "If TurboDOS is so good, why haven't I heard of it before?"

Perhaps it's because we have never run an advertisement for TurboDOS since its
original  introduction in early 1981. Not one. We've steadfastly  devoted  our
resources to enhancing and supporting TurboDOS, not selling it. That's why you
might not have heard much about it... or us... unless it was by word of mouth.

Despite  our  best  efforts to maintain a low  profile,  however,  the  market
acceptance  of TurboDOS has been nothing short of spectacular. Recent  figures
indicate that some fifty thousand TurboDOS networks have been installed during
the past four years. At end-user prices, that's $25 million worth of  TurboDOS
software and roughly half a billion dollars worth of hardware. We believe that
this makes TurboDOS the most widely used local-area network (LAN) software  in
the  world. (We always get a chuckle from the television ads that explain  how
much   LAN  experience  "Team  Xerox"  has  with  more  than  1,000   networks

Take a look at some of the computer manufacturers who have chosen TurboDOS  as
their  network  operating system. N.V. Philips of  the  Netherlands,  Europe's
largest  electronics  company, designed their entire P-3000 family  of  office
automation microcomputers around TurboDOS. Honeywell, the leading supplier  of
heating, ventilating and air-conditioning (HVAC) equipment in the U.S., and  a
major computer company as well, picked TurboDOS to automate their  nation-wide
network of HVAC dealers. NCR Corporation, a major computer manufacturer, chose
TurboDOS  for  the  file-server  in  their  Decision-Net  LAN  system.   Sweda
International,  a division of Litton Industries and a leader in  point-of-sale
automation,  is  using TurboDOS in their latest system designed for  the  fast
food industry.

Equally  impressive is the roster of users on five continents who have made  a
major commitment to TurboDOS by installing multiple systems. The United States
Army, Navy, and Air Force are major users of TurboDOS, as are the armed forces
of  Britain,  Australia,  and  Canada.  In  Great  Britain,  British   Telecom
(Britain's  equivalent  of AT&T) and Plessey (the British  electronics  giant)
each have dozens of TurboDOS installations, while Scotland Yard uses  TurboDOS
systems  to  solve  crimes. In the aerospace  field,  there's  Jet  Propulsion
Laboratory  (JPL alone has nearly 100 TurboDOS systems), NASA's Kennedy  Space
Center,  and  the  Lockheed Missile & Space  Division.  In  banking,  TurboDOS
networks  are  used  by Bank of America,  Guarantee  Financial,  Lloyd's  Bank
International,  and several major European banks. In the academic world,  UCLA
and USC have very large TurboDOS-based networks, with smaller installations at
Harvard and the Universities of Alabama, Iowa, Nevada, Texas, and  Washington.
Some industrial concerns using multiple TurboDOS installations include  Upjohn
(drug manufacturer), CCH Computax (largest U.S. tax-preparation bureau), Bally
(slot  machines),  National Can (containers), Coca  Cola  (beverages),  and...
believe it or not... Xerox!
