(I'd expect we'd have to play with byte ordering, data formats, etc.; but would we get past blatant low level I/O errors/incompatabilities?) More specificly, Archive has a PC tape unit they call Fastape (60MB) (not the Viper 150) that uses DC600A. Users would like to pull spectra and image data sets from those tapes to the SGI. More generally: Haven't had a good go-round about tape formats and "standards" since last May on this list ;-), at which time I shrugged and thought how lucky I was not to have to think about such madness! Sigh. :-( Looking around here, I find QIC-24 units (seem to do 60MB), QIC-02 units that are also described as QIC-24 (signal interface versus data format???), QIC-150 (150MB) that are also described as QIC-02. The archives of this list also introduced QIC-120 & QIC-11 "standards" (whatever MB). The Fastape unit mentioned above was suggested to me to be of a QIC-36 persuasion. Catalogs indicate QIC-40, -60, -80, and -100 that seem to cross back and forth between standard and mini cartridges. So, WHO writes all these "standards"? Where are such "standards" documented? Anybody already sort all of this out, maybe have some sort of a master reference list? Or does one call in a QIC con$ultant? (As an aside, I even noted a mail order ad describing a flavor of mini cartridge (DC2000) adhering to the "QIC-2000" standard. Oh, come ON now...) In the QIC-sand, Jack
