[comp.sys.mac] NTSC video on MAC II

cc4b+@andrew.cmu.edu (Christopher Brian Cox) (06/29/89)

  I have been told several times that there is a way to make the Apple Video
card (on the MAC II) output NTSC video (ie: suitable for a TV or VCR with
video input).
  I found an FKEY that was supposed to do this, but either it is damaged, or
it will not work with the current system.

  Does anyone out there know anything about this?
  Could you forward the information to me?

Thanks,

Chris Cox

Sorry, I don't know how to reply directly to your account. I don't think 
this board echo's private mail.
Macintosh News Monday, June 19/89 pg 13 bottom left. "Apple's Video
Freebee"
At the spring worldwide developers conference, Apple formally confirmed
what many colour video graphics card designers already knew for more
than two years: that Apple's 8 bit 640 by 480 colour card can be
modified to produce NTSC colour video as well as the RGB video it
delivers to the Mac."
Apparently Apple distributed a disk that contained details of cable and
board modifications needed to make NTSC output possible.
