Re: DDS-3 tape drives

the print parameters is to send the escape sequences from the hp3000
to the printer, (this will work on laserjet 4 or 5's), the following
example show the exact syntax:

FILE LPCARL4;DEV=LPCARL04,10
ECHO %-12345X@PJL DEFAULT ORIENTATION=LANDSCAPE >*LPCARL4
ECHO %-12345X@PJL DEFAULT FORMLINES=66 >*LPCARL4
ECHO %-12345X@PJL DEFAULT LPARM:PCL SYMSET=ROMAN-8 >*LPCARL4
ECHO %-12345X@PJL DEFAULT LPARM:PCL FONTNUMBER=0 >*LPCARL4
ECHO %-12345X@PJL DEFAULT LPARM:PCL PITCH=16.67 >*LPCARL4
ECHO %-12345X >*LPCARL4

     I have the spec sheet in my hands. Bullets include:

     . DDS-3 format: maximizes reliability; capacity, transfer rate, and
     cost effectiveness

     . High capacity: 24 GB with 2:1 data compression, 12 GB native.

     . High performance: 2 MB/s transfer rate with 2:1 data compression
     1MB/s native

     . Read-After-Write data verification for high data integrity.

     . Built-in hardware data compression.

     . Fast file search.

     . Full read and write compatibility with all DDS-2 and DDS tape
     drives.

     . Advanced head-cleaning mechanism.

     Required kernel patches:

        MPE/iX 5.5 power patch 1. Power Patch 1 (C.55.01) or Express Patch
     1

        Comes desktop of internal.

        That's all I know since I just received the data sheet yesterday.

We are looking at replacing our old DDS tape drive with a faster one.
At this stage, it was looking like being replaced with a DDS-2 drive
rather than DLT - our system just isn't big enough to justify the
extra cost of the DLT drive as well as having to buy Orbit's backup
software.

Anyway, last week I read that HP is releasing new DDS-3 tape drives,
claiming significantly faster data transfer rates.  I was wondering
if anyone has heard anything about them - good, bad or other?  If
no bad reviews, then I will hold off ordering a DDS-2 drive until the
DDS-3 drives are available - who knows when that will be in Australia
:-(
