Protel PCB was marketed internationally by HST Technology since 1986. Originally it was sold only in Australia. It has roots back to 1985 when the company launched the DOS-based PCB design tool known as Protel PCB (which later emerged into Autotrax and Easytrax). Altium Designer was originally launched in 2005 by Altium, known at the time as Protel Systems Pty Ltd.
