Thanks man. So without the SX-1 and SX32 boards the Commodore Amiga CD32 won't connect to this monitor.
It will work with the composite output from the CD32.
There a video on Youtube of some guy doing an RGB video mod on a CD32. The output is a 9 pin d-sub and he used it for connecting to SCART but it should be good for connecting to a an RGB monitor if you made the right lead.
