Someone sent me an E-mail not long ago that, in a very confident tone, advised me that my quest to find an RRD40 or RRD50 would fail, as the controllers were 'impossible' to find. Never say 'Impossible!' to a technoid. ;-) I just closed a deal for TWO RRD40 CD drives, one controller, cabling, and technical manual, all for $65 + shipping & COD charge. As a point of interest, another company out of Chico, CA offered me an RRD50 for $40, and a controller for $125! (sheesh!) I've told them (politely) no, thanks, on the controller. However, it occurs to me that there may not be any difference in the controller for the RRD40 and RRD50. Allison or Tim? Is this, in fact, a true statement? Can either drive be used with the M7552 controller? If so, I'll just order the drive from them and hunt around for another controller later. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.
