Hi Jasper, I don't know if there is a preferred choice of monitor but most monitors that can accept digital TTL levels and sync down to 15kHz should work with a bit of persuasion. I managed to get my S-550 to drive an old NEC Multisync3D VGA monitor by wiring a pair of transistors in the cable to invert the hsync and vsync signals similar to the way the Roland RGB25i cable worked (there is a schematic of the RGB25i cable on the S-760 site http:// s760.us.tt/ under accessories->monitors). I can provide a wiring diagram for my home-made version if you are interested (or if anyone else is). This page has a list of monitors for old amiga computers which should also be compatible with the Digital RGB signal as long as the correct connecting cable/circuit is used: http://www.amiga-hardware.com/showcat.cgi?CATID=26 Hope that's helpful Chris P.S. my multisync 3D worked great with the 550 but it recently died of old age (and dust inhalation by the looks of things) so I'm currently considering getting one of my 2nd year undergrad students to design a cheap scan doubler as their project so we could all throw the old monitors away and plug our samplers into our flat screens instead...
