    The connector is a DB23.  Yup a strange animal....
    Send me mail and I'll set you up...

    Is the VT241 a multisync monitor?  Will it work with Flicker Fixer?

    Not that I have any of the above.

    VR241 is not a multisync monitor.  It works on the standard scan
    freq of 15,750 khz.

    Also, the screen will be smaller, read LARGE border all around and
    if you tweak all the ajustments, you end up with a small border.
    You need 4 cables: pins on DB23
    			3		RED
    			4		GREEN
    			5		BLUE
    			10		COMP-SYNC
    			16 to 20	Ground
    
    I made an adapter from a DB25 (F) with two pins hacked off on this
    I soldered a small 1.5" x 2" pc board with the etch side soldered
    on the ground pins, this made for a strong mecanical bond.  On the
    board I mounted 4 RCA panel jacks connected to the right pins. 
    I then used regular RCA patch cables with RCA to BNC adaptors on
    the VT241 end.  Works great when we bring an Amiga in the office
    for club meetings, saves us lugging the monitor.

    I have been using a VR241 at work for several months.  The only
    drawback is working in 640x400.  Interlace really flickers.  That's
    why I have two monitors on my desk, VR241 and a long persitance
    monichrome.
    
    I enlarged the image on the VR241 by tweeking the internal adjustments.
    Be careful if you do this, I accidentally shorted out the monitor
    with a metal screwdriver.  Something blew.  Whatever it was, it
    resetted when I turned the monitor off and on.  There is now a 1/2
    inch black border around the screen display.

    Play with the colors I use interlace mode all the time with my VR241
    I also used MoreRows to bring it out a little larger than 640X400.
    I use a black background and Amber characters.  Then I play with
    the contrast and intensity to reduce the flicker until it is
    practically gon

    I don't have my DEC monitor in front of me but doesn't it only use
    3 BNC connectors into it? I thought sync was thru one of the RBG
    (blue?) connectors. I happen to have an extra Amiga cable and plan
    to make an adapter for it by going from the 6 pin round 1084 connector
    of cable to the 3 BNC of a DEC monitor. I'm confused, what's the
    4th connector for and where does it go?

    The fourth BNC is for SYNC. I believe that the RGB signals do not have
    any sync signal "mixed" in. Some DEC equipment mixes the sync with the
    the green in the form of an RS170 composite (NTSC??).
    You mentioned connecting the output of the six pin DIN connector to
    the DEC monitor (VR241?). I'm not sure about the 500/2000 but on the
    A1000 it's the composite video output. The A/D RGB output is the 23 pin
    connector. I followed the instructions in note 550.1 and it works great.
    Also, if you have a DB25 connector, and you're a cheapskate like me ;^) ,
    perform the hacksaw "surgery" mentioned in said note and save a couple
    of bucks. The pinout is also mentioned a couple of replies previous
    to yours.

    Still confused? Don't feel bad, I read what I just wrote and it makes
    absolutely no sense to me...

    I picked up a DEC RBG cable and in fact it only has the 3 coax (BNC)
    lines. Yes, I'm using a (well, a old off brand that works with my
    PRO380) VR241. The PRO, and I suppose othefr color units mix sync
    in the blue line. Does this mean that I can't simply tie the blue
    output and sync from the Amiga 500 to the blue BNC going into the
    VR241? If so, I'm back to the drawing board.

	With only three BNC connectors, the sync is on the GREEN, not the
blue.  The VR-241 will take either three connectors that way, or four
connectors (RGB and Sync on a separate line).  There is a switch on the back
to tell it to either sync on Green, or Sync.
