[Heathkit] Mu matic keyer SA-5010

[Jim Brannigan]

Does anyone know the location for the manual? (I tried BAMA)
I located a schematic and that is a start.
This unit has been in my junk box for many years and I have no idea if is 
operational.

In lieu of a manual does anyone know the power supply voltage required and 
are the internal batteries just to hold the memory or are they also needed 
it power up?

TNX,
Jim
