Subject: ANN: AFSFiler

Hi,

Read and attempted to format a Rodime drive on a RiscPC with a Morley SCSI
card and the formatter software under 65Tube. FileStore wasn't having it,
but the layout *looked* okay.

Also used the same basic setup to image my MDFS drive when the hardware toasted
itself.


Best wishes,

Rick.
