   I've had my Diamond Scan for about a year now and it seems to be doing 
just fine.  My only complaint is that I hate those scanlines in between
the letters on the screen, but that's my amiga's fault.
	
	As far as wiring goes, I WOULD NOT trust the AC article that
appeared a few months ago.  ie who wants to risk "circutry failure"

	Here's my wiring diagram:

amiga                               Dia. Sc

3 ---------------R-----------------  2         I use all these grounds
16 ------------gnd-----------------  3         because my video is 
4 ---------------G-----------------  4         carried by three coax
17 ------------gnd-----------------  5         cables.
5 ---------------B-----------------  14
18 ------------gnd-----------------  15
19 -----------sync gnd-------------  1

Now the tricky part:
		--------
11 -----hsync--|1      2|---------   16
	       |	|
	       |	|
12 -----vsync--|3      4|---------   17
	       |	|
	       |	|
23 ----5V------|14	|
	       |	|
20 ---gnd------|7	|
		--------
		74ls04

	Why all this? Well I did it because it was the first
combination I found that worked, but a while ago someone posted
a similiar fix. He said that the monitor loaded the sync outputs
and this caused the computer to look for an external system
clock, hence nothing happens. Any comments out there?

	Goood luck,
			Bob
