Rather than let the magic blue smoke out of my intercom, I decided to see how this thing was arranged. So, after a long evening with the multimeter, I've come to the conclusion (confusion?) that this isn't for Melco or Valcom; maybe Teltone, but not their 19 station units.

I guess it will go on the shelf of odd eBay things.

Anyway, for the curious, here's what I toned out. Where the pin is labeled XConn in the 66 block column, it doesn't appear on the block, but is connected to the other AMP on the pin(s) shown in the XConn column.

Code
AMP #1  66 Blk    Color   XConn         Melco    Teltone

That looks like it is for a Teltone M416-22 unit to me.
