High Country Service Data is a family owned and run company whose origins date back to 1973.

In 1973, Stephen Rendell established a Television sales & repair business in Exeter, a small village in the Southern Highlands of NSW. After working from home for several years, Steve decided to move his service business to Moss Vale (about 10kms north of Exeter), where the business remained until 1992.

In 1987, his eldest son Warwick started working with him part time, and in 1989, after completing his School Certificate, joined the business as a full time Audio technician, servicing CD players and consumer Hi-Fi equipment.

Throughout the years that Moss Vale Vision and Sound (as the business had become known) had been running, Steve had made a special point of collecting and cataloguing Service Manuals. A Service Manual is a handbook supplied by the manufacturer of electronic equipment to their service centres to enable repair of particular units.
