Switchmaster 900 programmer

[Robert Reichenb]

Our programmer is +- 30 years old and the clock function is getting erratic. I do not like digital display devices. Does anyone have a new/good order, model of Switchmaster 900? Thank you; RJR

Just buy the 805 and swap it, same connections I believe, just a slightly newer timer
