Lines: 20 -------- Several people have commented that they are having problems upgrading their CMS 80 MB drives to System 6.0. (I have *not* yet upgraded mine. I'll wait for Apple to fix some of the problems first...) The symptoms described (the drive hangs after displaying "Welcome to Macintosh" sound a lot like the problem I had when I first installed our drives. This is what I found: CMS 80 MB drives *do not work* with AutoBlack, that marvelous little screen saver that gets named MacsBug and uses the alternate screen buffer in the Mac Plus. The drive hangs *exactly* the same way (after displaying "Welcom to Macintosh"). My theory: The driver for the CMS drives was not correctly written, and thus is somehow dependent upon the memory layout in the machine. This changed with System 6.0, and the CMS driver broke. CMS, shame on you! Herb Weiner UUCP: !tektronix!midas!herbw AppleLink: D0521
