It is a freeware download and also available in a stripped-down version marketed as Easytrax. History In 1985, Protel Systems developed the DOS-based PCB design tool Protel PCB, which was sold only in Australia. Protel PCB was marketed internationally by HST Technology since 1986. In October 1986 the San Diego-based ACCEL Technologies, Inc. acquired marketing and support responsibilities of the PCB program for the US, Canada and Mexico under the name Tango PCB. combining it with their own Tango Route. In 1987, Protel launched the circuit diagram editor Protel Schematic for DOS. In 1988 the company launched Autotrax for DOS in the US as well. A stripped-down version of Autotrax was marketed as Easytrax. Autotrax was sold throughout the world until the company ported the application to Windows 3.1 to create the first Windows-based PCB CAD tool, Protel Advanced Schematic/PCB 1.0 for Windows in 1991, which was the forerunner to the software Altium Designer.
