Jupiter 4 Prototype

This is the same Jupiter 4 prototype I posted about back in June. Here's a pic of it from the Brodr Jorgensen (UK) Newsletter from 1978. I wonder if it might have almost gone into production with this design since they'd already started advertising it?


  1. Ah it's great to see a larger and more and more clearer image of this, even though it still a bit unclear. I wonder how many of these were made? and if it sounds different from the normal Jupitar 4's.


  2. I doubt there were more than a few made. And I would imagine the differences where only cosmetic. The front panels seem to be virtually the same, and you can see in the pictures you sent that the prototypes also have the same buttons along the bottom under the keyboard.
