[Central-Electronics] Adding a Central Electronics sideband slicerto an HRO-60

[Mort Denison]

Thanks for the reply, Jim.

After spending a few nights with the manual I downloaded from Bama, it looks
like the hookup is fairly straight forward, including the AP-1 and AP-3
accessories which allows the Q multiplier to work when the slicer is off.
It's in line for a recap in the next few weeks.  I'll report back if it's
not as simple as it looks.
