Plus Mystery Port

[Mac128]

Is this a picture of a video port of some kind?

 

[equill]

Conceivably, but a realistic answer may lie in the text of the warning label that is visible in the rearside view of the Mac.

I've seen ports like those used for microphones in a PA system.

That port looks like one of those light plugs you have on certain Front of House mixers.

DIN 45326 -- used for many older video monitors.

Weren't there Keyboards using that plug, too?

You're right. It's a Kodak / Sayette datashow pad connector. It was a very common mod in the day. If you open the Mac, there will be a little video daughterboard in there connected to the socket.

Gotta love that rust! Well, at $44.99 ($20 for shipping) you can't complain too much. But regardless of the original purpose, in light of the condition of that connector, I wouldn't expect it to function as it once did.

midi?

note quite. Its more used in the professional lighting. Some...

 

[MacMan]

It could possibly be a TTL video port for connecting an external monitor, as this connector was quite popular in the 1980's.

I'm still kicking myself about selling two of the Kodak/Sayette Datashow LCDs for work without realising what they were.

There's an extensive thread here discussing these video out mods which a little search fu should reveal
