Sorry in advance for the cross-posting.

I have a Gates model 944-6701-002 cart playback machine, set up for mono. I don't know if this 
works, and don't have any documentation for it. Here's what's present in the electronics cage:

-- left channel playback card
-- 1khz cue card
-- psu card

It's got Nortronics heads, look in decent condition. Heads are 2-gaps.

Apparently, these were made to be configured for either mono or stereo, this one's mono. There also 
were various cue-control signals, this one is 1khz.

Early solid-state, build like a brick you know what. It's heavy, about  30lbs, more like 40lbs when 
it's packed up.

Ping off-list if interested. Otherwise, Monday is dumpster day.
