Re: Help needed with Apple IIgs monitor

Sorry if I've misinformed anyone, but that's what I was taught.  At least
some people agree with me.

PC serial port cable being called a DB9, with picture:

Macintosh video connector labelled DB15, with picture:

Joystick cabling named as DB15, with picture, and mentioned as working as a
Mac monitor extension cable:

Of course, one thing I didn't mention was that my ascii drawings aren't to
scale.  The HD15 *is* the same size as a D?9 connector, which makes it the
same height as the D?15.
