PLEASE NOTE:
There have been a number of Jupiter ACEs sold on the auction site EBay as an ACE 4000. If you can NOT see the monitor output socket and also a small slide switch under the machine then this is not a North American ACE 4000. It could be standard 3K Jupiter ACE housed in an ACE 4000 case. Why not send us some images of the PCB so we can authenticate it?

Introduction.
The ACE 4000 was intended for the American market with only 800 reportedly ever made. The reported number of Ace's sold before Jupiter Cantab closed for business was around 5,000. The Ace 4000 has a different PCB designs, issue 3, similar to the issue 1 and 2 with some extra modification add to the PCB. The specification is the same as issue 1 and 2 Ace's. An extra output socket for the monitor signal. On the bottom of the case there is a small slide switch to select the VHF TV channel 3 or 4. A ROM-Deselect feature signal is available on the edge connector, which means that the standard Aces ROM could be switch out and external ROM's added. The case is also different, being stronger, injection moulded instead of the yoghurt pot type of case the issue 1 has. The speaker / buzzer can also be seen though the grill, as it's mounted on the bottom of the PCB. The Ace 4000 was destined for the USA market, probably because of the positive review FORTH received in the USA magazine BYTE in 1980's.
European Ace 4000? It seems that some European Ace 4000's were made how many we do not know. They do not appear to have the channel slider switch on the bottom of the case like the USA version. There seem to be mystery around the Ace 000 was there a European Ace 4000 with the features of the USA version, or was the European Ace 4000 just a standard 3K Ace in a better case? - If you have any images of a European Ace 4000 please send them in!
