I've used 32k crystals with the F84(A) many times and always used 2 x 100pF and no resistor. They've generally been for real-time clocks in battery mode, so frequency was important. I've not had any crystals fail or drift -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
