Status of the Project


The Ultimate-II+ hardware is stable and in full production. Every few months a new production batch is started, that matches with the demand.

The next production batch is expected to be ready mid-January 2018. All current orders and many coming orders can be satisfied with this production batch.


At the end of August 2017, the very first prototypes were received. Functionally these prototypes were quite good. Many hardware blocks are working as they should. However, also some problems were encountered, of which the most severe were:

  • EMC compliancy: these prototypes were quite noisy
  • Power supply. It turned out that the 5V rail was too weak to power heavy cartridges like SuperCPU and even two SID chips at once. Well, it could run, but it simply didn't boot up correctly with two SIDs.
In the mean time, the power supply circuit has been redesigned and also prototyped separately. This was successful, and the new power supply circuit has now been integrated into the Ultimate-64 board design.

The Ultimate-64 production has started mid-December. Components are on stock for 500+ boards. But, because many changes were made to the board for the aforementioned issues, the production will ramp up slowly. The first boards are expected at the beginning of February. Then, when everything is OK, more PCBs will be ordered and assembled with the components on stock. This means that up to around 500 orders can be satisfied by early April 2018. Also, new components and PCBs will be ordered for the next (third) batch of boards, depending on the demand, to serve your orders as quickly as possible.
