Atari BSR/RTC Card.  In the late 1970's through the early 1980's the leader

in early Home Automation was X-10. 

 

The History of X10

Way back in 1970, a group of Scottish engineers formed Pico Electronics. The company developed the original single-chip calculator.  In 1974, Pico developed a programmable record deck in partnership with Birmingham Sound Reproducers and the seed was sown for a remote control for lights and various appliances. By 1975, the company’s tenth project sprung to life, named X10.

It took 3 years for products to hit the stores after Pico and BSR morphed into X10 Ltd.

The first system packaged was basic but effective:

  • Command Console

  • Appliance Module

  • Lamp Module

A timer and wall switch module soon followed and X10 was fully up and running.

The 1980s saw the introduction of a computer interface (CP-290). At the midpoint of this decade, BSR faded into oblivion with X10 (USA) stepping in.  This is where Atari enters the picture.  Seeing that this is a popular method of controlling devices through the home and with the CP-290 having come out,

Atari saw the next logical step - to create a BSR type X10 Interface and Remote Transmitter Card to be able to allow an Atari XL home computer to fully manage an entire home, from lights to the thermostat to the outside sprinklers.  No physical BSR/RTC X10 cards for the Atari 1090 have been found (yet), but given that the other proposed cards from Atari have surfaced, it is still possible that a prototype BSR card may one day appear.
