Yes, it is an Enterprise. The MSX is not seen at the left, showing its video on the monitor at the back of the Enterprise. You also can see an Amstrad PCW at the right.
Actually the SymbOS computers are the CPC, the MSX, the PCW and the Enterprise, by order of development.
The (black) computer to the right with the green, purple/blue and black keys on the keyboard is indeed an Enterprise.
Although it has a Z80, this is not a MSX!
Like Manuel says the image shown on the monitor is from the 1chipMSX.
Yes, it was a video running SymbOS on the OCM, The Enterprise is also used for testing Symbos..i think this video is during the driver dev. period. That is Prodatron his workspace I have seen it in real so it is pretty real as well..
