I've just used dispcal from this beta, with a DTP92Q. I attached the results, and those from the v0.60... There are differences, but I don't know which one is better.
I had reports that the DTP92Q doesn't work on V0.60 (the 'Q' being the USB version of the serial DTP92). There are subtle difference between V0.60 and V0.70Beta1 with regard to the exact nature of the target curve, especially near black. There were some discussions on the mailing list a while ago about this. Graeme Gill.
