Racing Simulation Hobby Phase

A series of home-built Formula One simulators were developed by Carey Kriger under the Krigshak pseudo brand between 1987 and 1994, mainly because there were no commercial software or hardware products realistic enough to satisfy a serious racing enthusiast at that time.

Development started as an interesting side-project while earning an Electrical Engineering degree from the University of Texas at Austin, and continued as a weekend hobby during five years working for Houston Instrument.

All needed software, mathematics, graphics, sound, electronics, and mechanics were basically developed from scratch.

Much was learned, and much fun was had racing with friends during this era!


1st Generation Krigshak F1 Simulator:
(circa 1987)

Based on an original IBM PC with 8088 CPU at 4.77 MHz, CGA graphics, and monochrome monitor.

Software supported relatively-realistic vehicle physics, with 2D top-down graphics initially, and 3D wireframe graphics later.

Hardware interfaced via parallel port and custom wire-wrapped circuit boards.  Belt-driven force-feedback steering!

Written mostly in Assembly Language with some C.









2nd Generation Krigshak F1 Simulator:
(circa 1989)

Used a 20 Mhz 286 CPU and was linked via RS-232 to the 1st Generation simulator for head-to-head racing.

Software supported 3D wireframe color graphics with sprite overlays, and a complex vehicle physics model that is still largely intact today.

Hardware interfaced via custom wire-wrapped ISA board.

Written mostly in C with some Assembly language.

3rd Generation Krigshak F1 Simulator:
(circa 1991)

Featured a stylish triple-monitor enclosure, brake pedal with a mini-football as the resistance element, a new anti-backlash steering mechanism with paddleshifters, and more.

66 Mhz 486 CPU and triple Texas Instruments 34010 graphics boards.

Software supported 3D shaded-polygonal graphics spanning three monitors, running on MS-DOS.





4rd Generation Krigshak F1 Simulator:
(circa 1994)

Raised the chassis off the floor and fitted casters, along with a proper racing seat with integrated surround-sound and bass shaker, and new machined (non-wooden!) steering, pedals, and shifter mechanisms.  A test mule for what would soon become Digital Vehicles' first commercial simulator.

266 Mhz Pentium CPU and triple Texas Instruments 34020 graphics boards.

Software supported 3D shaded-polygonal graphics spanning three monitors, running on MS-DOS.







Racing Simulation Business Phase

Digital Vehicles Inc. was founded in 1995 with backing from investor George More, to commercialize the technologies developed during the hobby phase.  Amazingly, DVI has now provided interesting full-time employment for over 20 years, and counting.


5GF1 Digital Race Machine
(with triple 20-inch monitors)

DVI's first commercial prototype simulator was a more-polished but still quite raw version of the last Krigshak model, but featured a proper metal frame and machined components:



The 5GF1 debuted at the 1995 Long Beach GP race party sponsored by Grand Prix Tours and RACER Magazine, where it was tested by several famous Indycar drivers and other enthusiasts:


That was followed by a nationwide tour of automotive magazines, racing schools, racing events, and entertainment centers:






Pacesetter 8000 Series Racing Simulators

These were DVI's first polished, fully self-contained products, intended for upscale entertainment venues and corporate marketing purposes.




Pacesetter 8127 Racing Simulator
(with single 27-inch monitor)

Debuted alongside the 5GF1 prototype simulator at the 1995 IAAPA show in New Orleans:


Pacesetter 8133 Simulators
(each with single 33-inch monitor and acceptor for $1/5/10/20 dollar bills)


Pacesetter 8327 Formula and Deluxe Simulators
(with three 27-inch monitors and optional mini-racecar bodywork)


The 8327 models debuted at the 1996 IAAPA show in Orlando:


Along with a custom demo system for SEOS Displays from the U.K.:

Camber Entertainment and Pulseworks


An F1-style fiberglass body option for the Pacesetter was produced in 1997 by new distribution partners Camber Entertainment U.K. and Pulseworks USA.  The sleek new physical package along with ever-improving software and graphics helped boost distribution worldwide.


Pacesetter Grand Prix Simulator



Pacesetter Rally Simulator

A rally model was also developed with Camber, using third-party rally racing software with Digital Vehicles components:




Pacesetter Simulators were installed in linked multiples at various entertainment venues around the world, such as:


Memphis Motor Speedway:
Memphis, TN


Space Center Houston:
Houston, TX


West End Marketplace:
Dallas, TX


Monde Virtuel:
Montreal, Canada

These two simulators happened to catch the attention of one particularly-interesting customer in 1997, F1 racing driver and Montreal resident Jacques Villeneuve, who went on to win the Formula One World Championship that year (obviously benefiting from practicing on the Pacesetter, ha):


By the early 2000s, there were 40+ Pacesetters and an additional 60+ Pacesetter-derived custom simulators in the wild, scattered across a dozen countries on four continents.





Global Activities

Together with associates in the USA, Belgium, Switzerland, France, and Hungary, we helped design and build a fleet of big, impressive, and mobile racing simulators for corporate brand promotion worldwide.

Other Corporate Marketing Simulators

We did a lot of tradeshow and racing event rentals over the years, often featuring customized on-screen graphics and matching physical bodywork:





Illusion Inc.

Indycar and NASCAR Simulators

Produced large-scale installations of multiple, networked racing simulators, based on source-licensed Digital Vehicles physics/control software, steering components, and related custom development support.

Deployed at Sahara Speedworld and NASCAR Cafe in Las Vegas, ESPN Zone in New York's Times Square, and elsewhere:




GM Driving Technology Lab at EPCOT Center

A dozen "Future GM Driving Technologies" simulator stations were produced in conjunction with BRC Imagination Arts and VisionQuest, using some simulator hardware components and know-how from Digital Vehicles:


Software Licensing and Custom Game Development

Digital Vehicles' vehicle physics code and VisionQuest's graphics code were licensed to form the basis of several consumer game titles:




Airport Emergency Response and PatrolSim Prototype Simulators

We sold a couple of Pacesetter cabs (without software) and some custom forklift controls to GE I-Sim corporation, and helped integrate our hardware with their software.  This enabled them to rapidly demonstrate to potential customers several prototype "low cost" triple-screen training simulators, including an airport emergency response simulator and what became their market-leading PatrolSim police simulator.

Digital Vehicles Inc.

Commercial Driver Training Simulation Business Phase

A gradual de-emphasis of racing simulators in favor of driver training simulators began in earnest around 2003, with the design and production of a new product line.

A new Windows C++ software package optimized for driver training (called "TRAINER") was created, by combining the core vehicle physics and simulation control code from the Pacesetter racing simulators, with a new DirectX-based graphics engine and 3D visual models from David Hooper of VisionQuest (who remains a key development partner to this day).
