Last weekend my brother Henrik, Pep and I met Willy at the Slaskhack party in Falköping. Willys real name is Martin btw.
We sat down with Willy and he showed us his layout and schematic of the CT60e. It all looks very promising. It is basically an enlarged CT60 that covers the rear PSU mounting holes so it can get proper mechanical support at the rear. It has built in CTCM and footprints for motherboard acceleration components. These components are not mounted. PSU connector and SDRAM connector are like on the CT60. CPU socket is present.
The signal integrity issues of the CT60 should be solved now with series resistors near the 060. The ABE is now placed in the middle of the 060 bus, instead of the far end from the CT60 expansion connector. This made it possible to shorten the bus signals a few cm, and adds to better signal integrity.There are also series resistors outside the clock driver chip, which should render the SV/EtherNat/CTPCI clock filters redundant and improve stability. The 5VSB capacitor fix has also been added.
The CT60e PCB is now 6 layers instead of 4 as on the CT60, which allows more solid GND and 3.3/5V planes. The motherboard is now fed 5V and 12V through a downward pointing connector that mates with the old MB connector. The CT60e therefore reaches about 10 mm further to the right than the CT60. Not sure what that means for the old harddisk bracket. The connector should also add mechanical stability to the CT60e.
The project looked quite complete to us, and Willy said he would produce prototypes "soon". Not sure what that means though.
