Any info on Superior Electric Slo-Syn NTC

Hi Folks,

I've just bought my first mill and it has a "Superior Electric Slo-Syn
NTC (Numerical Tape Control)" system with it. It's my intention to fit
something PC based in time but I thought it would be fun to check out
the NTC first.

Does anyone in the group have any info on this unit that could help me
check it out? Operating guide, service manual etc, anything at all. It
has nothing at all with it, not ever a mains plug!


Any help greatfully received.


Andy.
