My only ST box (currently) is the 1040STF, so it has an internal floppy 
drive. Therefore, I've never paid attention to that connector. Never had a 
HD either... ;-)

... But the video connector is a 13-pin DIN which can be had from Mouser 
now, and might be stocked at Digi-Key. I have a few males & females of that 
connector ready & willing (whenever I get a round tuit, which won't be for 
a little while at least, as it's not high priority for me[1]) to design a 
converter cable to go from the Atari SC1224 monitor to a Tandy CoCo3 RGB 
port. AFAIK, they're compatible except the connectors, so it's just 
matching pins.

[1] The reason the cable's not a high priority is I have both Roy 
Justus's's's's ;-) CoCo3->VGA adapter, and Chris Hawks's's's CoCo3->SVideo 
adapter... so I can use both an LCD monitor & my 27" Sony Wega  tele as 
monitors now.
