I am sure a few people have a Quantum Design PPMS. Is anyone else here actively involved in building custom options, and writing custom software, or simply has a lot of experience with it. Quantum Design is (maybe naturally) cautious about giving out blueprints of the sample chamber and such. Did anyone produce a good blueprint of the sample chamber in some CAD format? Did someone make a list of undocumented GPIB commands? Does someone understand the temperature controller, how the options are registered in the Multiview Software... I have so many questions that are not really answered by the manual, and there are quite a few quirks of which I don't know if they are common. Is there a forum somewhere for this, a newsgroup, or a mailing list?
