Juergen Bosch and Ben Eisenbraun were quick to forward my request to Dave Gohara who's at WUSTL now. Dave was equally quick in pointing out that a universal binary of the USB-to-serial driver resides on his homepage (http://smackfumaster.com) in the Software -> Crystallography and EM Binaries section. Thank you! All it takes is installing the driver, rebooting, and plugging the adapter and dials in. Now I just have to find out which programs will actually take orders from dials. Andreas --------- Hey all, I've been trying to get SGI dials to work with a MacBook Pro running Leopard. I can't get my digitus USB-to-serial adaptor to work. The supplied driver is PPC only. As the chip is from Prolific, I tried the driver from sbgrid (David Gohara's work). That also seems to be PPC only. I tried to contact David Gohara directly, but he doesn't appear to be at Harvard anymore. Does anyone have dials working with a Leopard Intel Mac and would like to let me in on the secret? I should probably be using a PowerMate, but the dials were lying around collecting dust. I thought I might give them a second lease on life. Thanks. Andreas
