 I've hooked up a philips multi-sync monitor (CM 8873) to my amiga 500.

I got the description for the cable to make out of a german computer mag
called 68000'er. The cable they said to make went like this :

	CM8873		AMIGA
	  1      GND	13,16
	  3	 RED	3
	  4	 GREEN  4
	  5	 BLUE	5
	  7	 CYSYNC 10
	  8	 HSYNC  11
	  9	 VSYNC	12

  All fine and well, the only problem was that this didn't work!

I tried disconnecting the HSYNC and VSYNC signals, and then the connection
worked!

Just for fun I tried reconnecting HSYNC and VSYNC, while disconnecting
CSYNC. The result of this experiment was that the machine wouldn't boot
anymore!  The power light came on and that was it.  But if I connected the 
monitor once the amiga had booted everything seemed to work fine.
I tried this out friends amiga 1000, and it booted fine.

 Now could someone tell me :

	a: what video sync signals should I have hooked up to get the most
	  out of my monitor?

		1: CSYNC
		2: HSYNC+VSYNC
		3: both of the above

	b: Why doesn't my amiga 500 boot when the HSYNC and VSYNC signals are
	  present, while my friends 1000 does fine with the same signals?
	  And of course what can I do about it?

 While I'm "on the air" I'd like to send out a plea for someone to post GOFM,
because it sounds like a real godsend for anybody who is doing development on
the amiga. (like maybe even me:-)
