Portrait Display Connector Pinout

I came across a manual for the Macintosh Portrait Display, and it conveniently included a pinout of its quite hard to find video cable. Here it is in case you need to build your own.

most CRTs would take even up to an hour to reach their correct bias. For example, you wouldn't be calibrating a CRT color monitor until it was on for at least an hour.

Granted from a use perspective you could begin work as soon as the picture would display which would be only a few seconds.
