[comp.sys.mac] MAC II Video Card

henry@chinet.chi.il.us (Henry C. Schmitt) (02/28/89)

Does anyone know of a company making a Mac II video card for Zenith's
Flat Tension Mask Monitor?  I remember hearing a rumor that a
company was developing one but I don't remember any specifics.
It's a great monitor but Zenith won't make video cards for any
computers except their own (and other PC-compatibles).

Technical info. is:
Video Input:	Analog RGB video signal, 0-0.714 V peak-to-peak
		(1V peak-to-peak maximum), 75 ohm resistive.
Sync Input:  Horiz:	31.49 kHz +/- 1kHz, negative TTL
	     Vert:	60 Hz, negative TTL

Signal Connector:	15-pin subminiture D-type

If anyone knows of a video board which could drive this, please
let me know.  Thanx!

Does any one have a definition of the standard MAC-II video hardware
interface. In particular how can the board be put into RS-170
interlace mode with genlock. The various dribbles of information
that do exist allude to such capabilities.

Since the MAC software does not (probably never will) support these
modes I need the hardware bit definitions.

If you have a reply please send e-mail to:
