Help...
We have an application that writes directly to a 1/2" tape drive. Up to
now we have used a Xylogics tape controller plugged into a VME bus slot
on a SUN server. The controller provides a Pertec interface to the tape
drive. We are transitioning our products to SPARCStations which do not
have a VME bus. We need to support 1/2" tape drives on these machines.
The Obvious answer is to use a 1/2" tape drive with a SCSI interface...
But it turns out that not all the features and functions that are available
on the Pertec interface are are available over SCSI...
for example, from "man st":

SPARCstation 1 does not support ...
..., nor does it support 1/2" variable record length
operations, record space operations, or implied seeking.
We want a *real* start-stop-tape-driver that works over SCSI, *not* one
that makes a 1/2" drive look like a 1/4" streamer!
Any pointers would be appreciated.
