    Hi Admins,

    I manage an AlphaServer DS20E (early 2001 vintage), running
    Tru64 UNIX v4.0g, with all patch kits installed.

    This system has two Adaptec AIC-7895 SCSI controllers on the
    motherboard. When I first got the system, I remember reading
    something to the effect that these controllers were not
    supported for anything. Then later, I saw a note in the
    4.0g release notes implying that they could be used, but
    perhaps not for tape drives.

    As I have maxed out controller boards on my PCI bus, it would
    really be useful to me if I could use these Adaptec SCSI
    controllers, particularly if I could attach my Compaq DLT8000
    backup tape drive to one of them.

    Anybody know anything about these, or a reference I can study?
    If anyone has used them, do you know the part number on the
    cable and connector needed to connect the plug on the
    motherboard to a knock-out on the back of the pedestal box?
