Downloading design to Cyclone III board

OK, thanks. I think that the tutorial design is for Cyclone III, but not the LS chip. The JTAG and the device did match (EPCL2007807N), but the device in Quartus was set for another Cyclone chip. So when I changed that the design wouldn't compile anymore with the error message (165011) "altmemphy pin placement was unsuccessful".

I looked in the constraints file and did not see pin assignments. It looks like those are handled in pin-planner on Altera devices. Is there documentation on how to migrate pin assignments from one device to another? Assuming I've diagnosed this correctly.

Thanks for your help.
