Monitor was included and the SE 30 model even supported color. Nutek Nutek produced the Nutek One and Nutek Duet. These were not truly Mac-compatibles. These machines ran an OS by Nutek similar to the Finder that could run most Mac programs. Unfortunately, there were many, many incompatibilities, which kept the Nutek One and Duet from catching on.
All models come with built-in monochrome video and a monitor.
I have not heard much from them lately. It is software only. My favorite demonstration with Shapeshifter was to fire off System 7 on the Mac side, connect up to a nearby Mac server and mount a share, switch back to the Amiga side, open up AMosaic and browse the web while copying files on the Mac. Those who saw the demo were usually stunned. Most recently, I took a CD of several hundred Apple QuickTake 150 pictures that I shot over several months in Antarctica.
