I have a few refurbished Archive A2150S scsi tape drives for sale.
The 2150S is 120M with DC-600A, 150M with DC-6150 and 250M with DC-6250
tapes. It's embedded scsi and works well with the Nexus software and with
the PD stuff that Markus has been doing. The drive is a 5.25 inch, half
height with black front bezels. They come with a 90 day warranty from the
refurbisher and sell for $450 each. You'll have to provide your own power
supply and case, though they do fit inside an Amiga 2000 in the 5.25 inch
bay.
The easiest place to get ahold of me is at the BEJED number below,
8:00AM to 4:30PM weekdays Pacfic time... I only have a few, although I
may be able to find more at a later date.
To get one, send a check or money order to:
Bill Seymour
1701 SE Oak
Hillsboro, OR 97123
I'll ship on my dime, in the continental US...
[BTW, pretty much any of the scsidirect implementations should work fine
with these scsi drives, but I've had some troubles with the Supra... I'm
working at getting an updated driver that more correctly supports tape
type applications.]

I'm AIGH!! You people talking about SCSI tape drives are JUST doing it to torture those of us who are stuck with the A2090a controllers! You are SO cruel! So, that brings on a serious question: Has anyone managed to get the A2090a patched up so it can be used with a SCSI tape? I would be willing to pay for it, even! (I know, I could *pay* for a new controller, too. But I only have 1 SCSI drive, and 4 ST506. Another SCSI controller doesn't do me a whole lot of good, especially since I could hook up another 5 to this one, plus the tape drive.) Todd P.

The only bad bug is that the DMA chip does not get set up to transfer from memory to the device during a SCSIDirect writew operation. You can kludge your way around this by turning on bit 24 of the address of the memory you want to write out (ie. the data address). Bit 24 is the low order bit of the high byte in the longword of the address. As an example, suppose you wanted to write the contents of location $C00124 to the device... the address you would supply is $01C00124. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

I'm really suprised someone hasn't reverse engineered the 2090/2090a device driver to fix all the incompatibilities with current standards. It sure seems like it'd be a good product. Charge $19.95 each and sell one to everyone who has one of those controllers. I seem to remember someone (Maybe Dan James?) who had a scsi tape drive working on a 2090a. I don't know if that has ever been released, but I'll start looking around for it. If you're interested at all in going to a scsi only controller, Adaptec makes a SCSI<->ST-506 adapter (ACB-5500) that supports four ST-506 drives as one SCSI device. It sells for $79.95 from Computer Surplus Store (Weird Stuff Warehouse in their Computer Shopper ads.) I have a scsi direct utility for formatting the 5500 drives that Phil Staub did... :Todd P.

There seem to be two problems with using the 2090As with SCSI tapes that I hit while writing my own tape handler. One, usually referred to as the "write phase" bug, causes a lockup when attempting to do a scsidirect write to the tape (there's no problem with reads). Bob Mitchell disassembled the 2090A driver and discovered that this one can be circumvented by asserting address bit 24 of the address of the data to be written. My code works ok using something similar to the following: cmd->scsi_Data = (UWORD *) (&tapedata | 0x01000000); The other problem is tougher. When reading from the tape and writing to the disk (such as when doing a file restore from tape to disk), the 2090A seems to loose its marbles, as though it is stuck in a loop. HOWEVER, this problem only happens when the disk involved is on the SCSI bus with the tape drive. If the disk is instead on the ST506 connection, then this problem does NOT occur. Also no problem if restoring to floppy or RAM:. I should say that I have used only the 3M MCD-40 tape drive- maybe the 2090A likes other brands better. As long as we are discussing scsidirect circumventions, I'll mention what I had to do to get the Supra 4x4 running Series-II v1.10 to work. First, the byte count in scsi_Length must be zero. I know it sounds strange, but it works. Second, the process doing the scsidirect requests *must* run at a higher priority than the Supra "supradirect.device" task. The task runs at priority 10, so the process had better run at 11 or above. Both these things have been reported to Supra. I've finished my tape handler, and I sent it to the Amiga moderator 2 weeks ago, but it hasn't shown up in c.b.a yet. (what's going on??) The handler has been tested with the 3M MCD-40 tape drive running on the CBM 2091, Supra 4x4, and the CBM 2090A/ST506 combination. It may well run with other drives/adapters, but I don't have access to the hardware to test it. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bob Rethemeyer //"This is obviously some strange DrBob@cup.portal.com -or- // usage of the word 'safe' that I hadn't ..!sun!portal!cup.portal.com!DrBob // previously been aware of." - A.

From/to a SCSI Hard Drive? If so, is it "picky" about the brand/make of tape drive in use? I'm seriously considering a Wangtek 5150-ES drive. Will your tapehandler work with one of these? with a A2090a, even? (hope, hope??) Will other tape drives work? - Goodness! I've packed _so_ many questions in here! Sorry ;-) -dick -- Richard H.

From/to a SCSI Hard Drive? If so, is it >"picky" about the brand/make of tape drive in use? First, a clarification. It is not my tapehandler. It was written by Markus Wandel. I do believe it does work with the 2090A, though I cannot remember if I used it with my 2090A, or if I was using the HardFrame by that time. Markus indicated that he was using a 2090 driving a Northern Telecom 'Flashback' tape drive. >I'm seriously considering a Wangtek 5150-ES drive. Will your tapehandler >work with one of these? with a A2090a, even? (hope, hope??) The 5150 _should_ work. It worked on an Archive Viper the one time I tried it. That was probably on either the HardFrame or the A3000. > Will other tape drives work? Most likely. I have used it with the Archive Scorpion and a Wangtek equivalent to the Scorpion. Markus has used it with the Northern Telecom drive. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
