Beware the SCSI chain flaking out or the scanner overheating (at "104" degrees _internally_, e.g., 90 degrees room temperature (the scanner is self-heating since it has an internal fluorescent bulb which is always on when the scanner is on)). In my experience, either of these problems while using PowerScan reduces your NeXT to a hung PC --- it hard core hangs (all applications freeze, menus won't activate, keyboard is ignored; I believe even the NMI keys don't work!). I get the impression the scanner or PowerScan is/are (somehow) hanging the SCSI bus (thus effectively disabling all SCSI devices, including the hard disks :-(). I think this problem causes all unsaved and unsync'ed (by the OS) work to be lost --- even that of other applications or any background processes. Needless to say, PowerScan does not deal gracefully with scanner SCSI communications problems. So, now before using PowerScan, I disconnect my modem (so I don't lose incoming information, e.g., e-mail), and save all my work in other applications. Of course, now my NeXTstation becomes no more than a flakey, single-tasking PC, but so it goes to use my scanner... Also, I leave my scanner off when not in use. I reported this problem to HSD (most recently on 20 October). I have no idea what (if any) progress is being made to solve it. If anybody can shed more light on these problems (or even has solutions, heaven forbid :-), please let me know! Thanks, = Joe = -- Joe Grace <JGrace@TetraSoft.com> (NeXTMail preferred.)
