How many slots? I assume it's hex height. What (if anything) are the power input connectors?

Is there any reason to assume it's not a clone of a standard DEC backplane (Plessey stuff often was), the
'SPC' part of the name suggests a Unibus peripheral backplane ('SPC' = 'Small Peripheral Controller').
