U2+L boards will back in stock second or third week of May 2024.

Redesign of Ultimate 64 (Elite) boards has started. Specifications now fixed. Current Phase: Proto Board Layout. They won't be available until somewhere in 2024.


Back in 2008, the idea came up to create a cycle exact floppy disk drive emulation of the Commodore 1541 drive, and embed this emulated drive in a cartridge for the Commodore 64 home computer.  Today, the 1541 Ultimate and related products have become indispensable extensions for the Commodore 64 and 128 computers. According to some users, it has completely changed the way they use the old machine as it nearly eliminated the need for real floppy disks. In 2016, the Ultimate-II+ cartridge was released. This is the latest version of the 'Ultimate' cartridge.

The latest product is the Ultimate-64, which offers you a full C64 motherboard, with HDMI, Ethernet and USB ports, as well as the original tape port, cartridge port, analog audio/video port and serial port.
