I've had success in reading tapes written on 6157-002's with Mountain tape drives under SCO Xenix... Vise versa as well... I generally use tar for everything I do... However, I haven't had any success in taking an RT tape to work and reading it on the Apollo's. The Apollo's seem to choke on something. This is under SR9.7 and SR10.1 under both BSD4.x and SYS5Rx, however I have had limited success in reading an Apollo written tape on the 6157-002... Generally what happens is the RT will read about the first track on the tape and then return a "directory checksum" error. If I use the -h option with tar, the tape drive just goes back and reads the same stuff over and over again just asking me to "insert the next volume and press return". I've tried several different block sizes and nothing seems to work... I don't know what's at fault here, whether it's the RT, the Apollo's, or a combination of both... It took 3 tries before I finally managed to get GNUEMACS from work to my RT... BTW: Has anyone actually managed to get GNU 18.51 to work on an RT under AIX 2.2.1??? I can get it to compile without problems but when I run the executable, it just returns "killed"... "sdb" won't read the sucker in at all... In fact, trying to use sdb on xemacs just hung the machine... If anyone has ANY diff's at all for GNU18.51 for AIX I'd be forever in your debt if you sent them to me... AOS people need not send their sympathies. I'm jealous enough as it is... -- --------------------------------------------------------------------- UUCP: herb@blender.UUCP || ...calgary!xenlink!blender!{herb||root} ICBM: 51 03 N / 114 05 W "The other day, I......

Sure, it is a standard QIC-120/150 drive. And the 6157-002 is simply
a standard Cypher cartridge drive with a different color scheme and
three extra letters, for which you can pay an extra $1000 or so. :-)

I'm all ears... All I know is that I was configuring some RTs for resale by a client. I had written SCSI drivers for various tape devices, so having the extra slot filled by the IBM streamer seemed like a waste. I called the local Cipher distributor asking for a SCSI streamer, but unfortunately no one (at that point) had a 1/4" drive with a differential SCSI interface (thanks IBM!), but Cipher was thinking of making one just to satisfy the differential market. But he did mention that the box IBM supplies is _exactly_ the same box that Cipher sells under its own name, except for the IBM color scheme. I can't remember the details of the interface card, but I suppose the interface is industry standard if the boxes are identical. Call your local Cipher rep and ask, or call 1-800-4-CIPHER and ask tech support. -- A. Lester Buck ...!texbell!moray!siswat!buck

But now that someone posted the wrong answer... :-). ] The 6157-002 writes either QIC-120 or QIC-150, depending on the tape. The older drives don't know how to read that. The -002 drives *can* read tapes written by a -001. -- David
