Hello good people,
I recently purchased an sp-3 SCSI interface and successfuly installed it("SCSI installed") in my ASR-10.
The problem is that no hardisk respond to it. I tried the following separately (no chain):
> QUANTUM, ProDrive LPS 240S (240mb)
> CONNER CP30540 (540mb)
> QUANTUM VIKING 4550 MB 3.5 SERIES x three times (3 identical h.d. to verify h.d. is o.k.!!!)
They are in a good shape and spin o.k. They were used previously on pc's.
I tried to format them using the "format scsi drive" command and always got "unconnected scsi device".
I jumpered them for every possible combination including all id's, termination ,etc. I should also add that no diode blinking was seen on these h.d. nor negotiating sounds.
I also got that message when the scsi cable was disconnected!
The interface worked previously with a zip drive.
> Do you have any idea what's going on? what should I do? what am I doing wrong?
> Does the ASR-10 SCSI interface need a unique cable (I use a regular one for pc's: 25pin to 68pin)?
> Does the card need termination on its side? any jumper? O.S. version needed (I tried 1.6, 2.0, 3.53)?
Please, Please, help me.
Thank you,
Meiri
The problem may be that ensoniq looks first the lowest id value hd. If you have zip (operation system in), its id must be lower than hd. And if you want to load from hd, you must select it from edit system pages change storage device (the number of id). You can change that number manually ! (I dont know how to do it in pc)
Hei man, I have been dealing with it for 3-4 months!
I have, I think the answers and much more:
The are a number of SCSI standards.
ASR-10 sends scsi-I information - it is old.
This is normally sent through a D25 or 50pin.
Any device that receives SCSI-II & SCSI-I can operate with ASR-10 because the SCSI-II receives the data of SCSI-I in the right way through the pins.
SCSI-III which is called ultra-SCSI is normally sent through 68 pin connector. Any drive using this technology will not recieve SCSI-I data in the cabel (except where else written).
GAZ drive is an exception for this. It is dedicated to ultra-SCSI but receives also SCSI-II, and this is why it can receive SCSI-I !
The problem with internal drives is that the connector is always a rectangular one and not one of those "external to computer ones". I have worked alot with an electritian to produce a special connector (complicated) between those without success.
If you insist more than me you should search for a unique SCSI-I or II "external to computer case" which you will have to connect the internal drive inside of it and then you'll connect a normal cable from the case to the ASR-10.
Any way, the result of my research is that the best and easy thing is to search for a GAZ drive (I have one now)or at least a zip.

If you wanna run a SCSI hard-drive from an ASR-10, you need to install the drive in an external case. The one's I use have SCSI Centonics 50 pin interfaces. You also need to terminate the drive with a SCSI terminator that plugs into one of the Centronics interfaces.
Make sure the HDD's are SCSI.
From what I know a 2.1gb HDD is the maximum it'll take.
Only use SCSI cables.
I run a Quantum 1 gig HDD with no problems at all.
