Is there any way to program the A3070 tape drive to read tapes of lower density than 150M? I have several tape cartridges with tar files from a Sun system circa 1989 that I would like to read. I remember that the Sun had several different devices depending on which density you wanted to read, but I can't find anything like that in the UNIX documentation. I'd like to do this under either AmigaDOS or UNIX so any help would be appreciated. -- ------------------------------------------------------------------------------ David Lesle uucp: ncoast!lesle CLEVELAND AREA-AMIGA USERS' GROUP (CA-AUG) (216) 642-3344 (BBS) ------------------------------------------------------------------------------

Methinks the Huh? The 3070 works great under AmigaDOS 2.0, and if you have Amiga UNIX you should have AmigaDOS 2.0. Look at BRU... OK, so you don't like BRU. Well, BRU is using the scsi.device driver to do the dirty work. If BRU can do it then other packages should be able to do it too. Maybe C= could comment officially if the SCSI driver under UNIX can handle generic 150M SCSI tape drives? Not neccessarily optimally, but will they work at all? How about support for other SCSI devices? Is the main SCSI driver written so that subdrivers can hook right into it? For Tapes, CD-ROM's, foo and bar SCSI gadgets etc... -Rob

I need to read one now as well, so it's not an idle question, sigh | If AmigaUX is to be release as a software product and A3070 is the only |officially supported tape driver, many users would be no choice but to buy |this drive, even though there are no support for AmigaDOS.

But I might have hassle |in case of AmigaUX as well. I would like additional doc for my A3070 too. Early versions of Amiga Unix were on A2500 hardware, and came with Archive or Wangtek tape drives. Both functioned without obvious problems, altho I'm not aware of which jumpers were different from normal factory settings (other than SCSI i.d., which is usually 4 for Amiga Unix tape streamers). -- ,u, Bruce Becker Toronto, Ontario a /i/ Internet: bdb@becker.UUCP, bruce@gpu.utcs.toronto.edu `\o\-e UUCP: ...!utai!mnetor!becker!bdb _< /_ "Ferget yer humanity, do the poot" - devo
