I very much think so. Here are the connectors, soldering sides (!!), preferrably viewed in a monospace typeface: VGA: \ 1 2 3 4 5 / \ 6 7 8 9 10 / \ 11 12 13 14 15 / Mac: \ 1 2 3 4 5 6 7 8 / \ 9 10 11 12 13 14 15 / Connections are as follows: VGA : 1 Red 2 Green 3 Blue 4 GND 5 - 6 GND of Red 7 GND of 8 GND of 9 (no pin) 10 GND of Sync 11 GND when used as Colour mon. 12 GND when used as B/W mon. 13 H Sync 14 V Sync 15 - Mac: 1 GND of Red 2 Red 3 - 4 sense pin 0 5 Green 6 GND of Green 7 sense pin 1 8 - 9 Blue 10 sense pin 2 11 GND of Sync 12 V Sync 13 GND of Blue 14 GND of Sync 15 H Sync For starters, connect all three the sensing pins (Mac pins 1,4 and 7) together and then to GND of Sync (VGA pin 11 and or 14). See if that works. Fat chance it does :) >BIG question here. The 1705 monitor requires a special cable.

I know both ends are >smaller, but I have the adaptors/etc. You can check if your cable follows the above specs. Remenber to mirror the drawings above, because, as said, they represent the soldering side. I'd build this single cable first. Works neatly; HF doesn't like spider-like wire-messes. If it works, you then know for sure and you can easily proceed to a switchbox, or integrate the findings in the existing one. hope to hear, -mart -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
