Hi One and All,
I have a question about the Commordore Amiga's SCSI controller..
The A2091,A590 and the inbuilt Controller in the A3000...:-
I have a Microbotics HardFrame rev 1.9 which can see a
TEAC MT2-ST/45S 60 meg Digital Cassette Tape Streamer.
( I have got Tabu to work with both the tape-drive and the HardFrame.)
I set the drive up as SCSI ID 4 or 6 and it is seen...BUT when
connected to a A2091 or A3000 HDtools doesn't see the drive at all, Therfore
the software I have doesn't work :-
ANY IDEAS AS TO WHY THIS IS HAPPENING...?????
Please Mail me with any suggestions or ideas...
Has anybody got any tape drive working on
1) A3000 and 2) A2091

Also, on the A3000 under 2.0, you'll have to change the NEWCON: to CON:. Earlier this week I had Viper QIC 150 meg tape drive and a WangDAT 3 gigabyte DAT tape drive working with Tabu on my A3000. It looks like there's a problem with Tabu, because with both tape drives a few files were not restored, and none of the datestamps were preserved during restore. Still, it was very encouraging that both the QIC and DAT tape drives ran on the first try. I also tried an Exabyte 8mm drive, but it wasn't even recognized by the system. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 blgardne%javelin@dsd.es.com ...dsd.es.com!javelin!blgardne (I hope) {decwrl, utah-cs}!esunix!blgardne DoD #0046 My other motorcycle is a Quadracer.

I have hooked up an Exabyte 8mm tape unit via a GVP controller. I'm trying to adapt the BTN tape handler that was posted within the last two months. The GVP controller recognizes the drive (at least the amber light flashes :-) and I can read the device information, but that is about as far as I've gotten. The only documentation that I have for the Exabyte drive is the manual that documents the various SCSI commands. It doesn't give an example of what a driver might look like. The distributor (for Sun) says that it just uses the standard SCSI tape driver supplied by Sun. This, of course, was a tremendous help. Calls to Exabyte gave me the response of "We sell the hardware, we don't know anything about the software necessary to operate the drive". Not that this really suprised me. I did determine that the capacity is derived in a different manner than the BTN handler was using and recompiled the handler to take this into account. I've now got the handler reporting that it has "opened" the tape, but it later fails with an I/O error on the DoIO (?) call. I might be wrong about the call name. Its been a couple of weeks since I last had time to play with it. I strongly suspect that nothing is really being written to the tape yet. Does anybody have an example of an Exabyte tape driver, written in any human-readable language that they might be willing to share? Alternatively, could somebody point me to something that might give me a better clue as to what the Exabyte drive is expecting as far as the SCSI sequence is concerned? BTW, the Exabyte drive works just fine on a Mac IIci with one of the standard backup programs, so I am fairly confident that the drive itself is OK. >--- >Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 >blgardne%javelin@dsd.es.com ...dsd.es.com!javelin!blgardne (I hope) >{decwrl, utah-cs}!esunix!blgardne >DoD #0046 My other motorcycle is a Quadracer.

Yes. The tape unit is not acting like a disk drive when queried during the configuration by the driver software. I am surprised that the HardFrame recognizes it, since when I was playing with it, it would not recognize the tape drive either. I am not familiar with 'Tabu', so I don't know how you might deal with the problem. If it is a program you wrote yourself, you might want to consider some sort of ENV: variable to specify the driver name and the unit number of the tape. This is the way I did it on both my QIC and DAT backup programs. Another suggestion is to use a scheme similar to Markus Wandel's method, which uses a MountList entry. > Please Mail me with any suggestions or ideas... > > Has anybody got any tape drive working on > 1) A3000 and 2) A2091 Yes, several. I am having great fun with a DAT drive. I have it backing up at anout 7.7 megabytes/minute, and I can use it as a storage medium for individual files, with an average access time of 20 seconds to any file on the tape, if I know where it is. Not bad for a tape that will store 1.3 GBytes. -larry -- The best way to accelerate an MsDos machine is at 32 ft/sec/sec. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
