[comp.sys.mac.hardware] mac + hw question

ahlenius@motcid.UUCP (Mark Ahlenius) (01/25/91)

Can someone tell me if its ok to power up the analog board on a mac+ without
having the logic board plugged in?  Without having a schematic, I was concerned
that necessary sync pulses for the video driver circuitry might be missing
and cause problems in the driver circuitry (like permanent problems).

Also, a last plea for anyone who might have a schematic for the mac+ analog
board.  The repair books I have looked at only have partial schematics.

	thanks!

I'll second that request!  My mac+ lost its horizontal video yesterday, so
that all I have is a straight line from the top of the screen to the bottom.

If I had a schematic....
