Philips CM8833 (and some Magnavox) CGA models worked with Amiga also. They look almost identical to the Commodore 1084. (not 1084s) I guess Commodore (and Magnavox) bought them from Philips and put their names on. If you can't find and Amiga in your area, maybe one of these others are availabe. They use cables like this one to connect....
