Does > anyone know the pin outs for this adapter? Speak of the devil... I have/had the same problem with my old Multisync and just finished up the soldering project last night. The pin outs are: 9-Pin Connector 15-Pin Connector Signal Pin Signal Pin --------------- ---------------- Red 1 Red 1 Green 2 Green 2 Blue 3 Blue 3 Horiz. Sync 4 Horiz. Sync 13 Vert. Sync 5 Vert. Sync 14 Red Ground 6 Return Red 6 Green Ground 7 Return Green 7 Blue Ground 8 Return Blue 8 Sync Ground 9 Digital Ground 10 Ground 5 The connectors shouldn't cost you more than $6 at your local Radio Shack. The only problem I had was trying to find a housing for my creation and I ended up stripping a gender changer rather than buy a new one. I've tried my adaptor on a Paradise and a Trident card and it works wonderfully with both. I once did see an 8-bit ATI VGA card that had a 9-pin connector that would work with the original Multisync in VGA mode, but check it out ahead of time. My Trident card has both a 9-pin and a 15-pin connector, but the 9-pin is just an EGA connector and is absolutely worthless with my Multisync. -- Eugene Wang eggbert@bucsf.bu.edu
