CS s well known LINKNET line of LINK Systems which was on the market from 1992 2002 The Hybrid System was developed to allow a simplistic way to upgrade older LINKNET systems An upgrade is possible by replacing the hardware located at the instructor s desk with the Hybrid System s instructor hardware All of the other existing LINK hardware is backward compatible This allows LINKNET owners to gain the latest features of the Hybrid LINK System without incurring the cost of replacing all of the LINK hardware The Composite LINK System is the newest generation of LINK Systems to date and is the culmination of both the LINKNET and Hybrid LINK Systems It incorporates all of the features that PC instructors have come to know and love as well as a range of new features that these same dedicated users have requested over the years The Composite LINK System provides an upgrade route from a Hybrid LINK System The instructor s hardware is the same for both systems but the student hardware is not the same Applied Computer Systems Inc prides itself on every LINK System that is shipped out the door Each system is custom built and is tested in the customer s exact configuration This guarantees that the complete system is shipped and that all of the hardware works on arrival As always Applied Computer Systems Inc is dedicated to providing you the best quality hardware software and support available in the industry 2 0 System Components Ther
