Readers,

I have recently acquired a Heathkit uMATIC KEYER model SA-5010 without any
documentation. What is the power supply voltage and current requirements?
Is the center pin of the power receptacle +? I note several small memory
keep alive batteries on the board inside. What is the number of the battery?
