483.0. "Additional floppy drive?" by ADOV01::MANUEL (Over the Horizon....) Tue Feb 11 1997 07:10

    Any ideas?,
    
    My customer wishes to mount a 1.4MB floppy unit in the slot at the top
    of the 4100 pedestal normally used for the DAT tape, can anyone
    recommend a scsi floppy unit which may be mechanically adapter to fit,
    we are quite happy to do any metal bashing required.
    OS is Digital Unix.
    
    Reasoning:- floppy is used for small file transfer for mission data
    and opening the front door repeatedly is an issue.
    
    Thanks,
    Steve.

    The floppies on AlphaServers are not SCSI based. They have the same
    universal interface that any normal Intel PC has. I believe that you
    asking whether the currently integraded floppy drive can be moved to a 
    5 1/4 inch slot up above??
    
    Mechanically you need a bracket that beefs-up your 3.5" device to a
    5.25" device. They should be available at any PC parts store. I don't
    know what the implication might be as far as Warranty or Regulatory 
    (i.e. FCC emissions) and whether DEC would be liable for any of that
    or not.

There is no signal/power cable support for anything but a SCSI device on top of
a ped. So your looking at really having to hack up the system and build cables.
I am sure this would void the warranty....

    FWIW, while this has never been tested on the 4100/4000 platform, the
    SRM console should treat a SCSI floppy drive like any other SCSI
    device. It works fine on the 2100 platform and we (4100 and 2100) share
    the same SCSI class and various SCSI port drivers..
    
    The device would show up as a DK device and could be read/written/etc.
    Our FAT and ODS2 drivers could be used on the device as well. Not 100%
    sure how write-protected diskettes would be handled..
    
    Finally, I have been told that OpenVMS should work fine with said
    device as well (does so on 2100 platform). Can't speak for Digital
    UNIX, however.
