Fwd: [Incident 020627-000030] How to use a WD1002S-SHD MFM - to - SCSI (SASI?) adapter card
Hi John, In the past I've written drivers for both this chip (5380) and SCSI drives using this WD MFM interface board. It uses an old version of SCSI that is unlikely to be compatible with todays drivers. What you may be able to use are the very low-level SCSI "service" ulitities that came with some controller cards in the 80's. Adaptec used to supply a few low level utilities with there ISA controller cards so maybe they have something? Regards, Paul. John Robertson wrote:
The drive is SCSI, controller is NCR5380 http://www.cs.ucr.edu/~vahid/courses/220_f00/lab/project/5380.pdf if you want more info...
This is a reply I got from Western Digital about the SCSI to MFM interface board as used in the 9100A.

Discussion Thread Response (James K)06/28/2002 09:09 AM Hello John ,
This is all the information that we have on the WD1002.
Jumper functions (W17 to W22, R23, and W25 to W28)
The follow list explains the jumper functions.
W17 & W18 selects factory drive tables for the first hard disk W19 &W20 selects factory drive tables for the second hard disk W21 & W22 sects the controller and BIOS address ranges R23 enables or disables the Western Digital BIOS ROM on the WD1004A board W25 and W26 always OUT W27 sets the hardware interrupt (IRQ) value for the hard disk drive W28 allows the controller to operate with an XT computer when the jumper is OUT.

Regards, Customer (John Robertson)06/27/2002 08:50 PM I am trying to find information on an old interface card (1985) made by your company. This is used in an old Fluke piece of test equipment and I wish to back up the hard drive before it fails, however I am unable to access the hard drive with any of my SCSI controllers used in any of several operating systems - from Dos 6.22 to Windows 2K. Plus the backup utilites for this test equipment no longer seem to exist so I am trying to mirror the drive to a second (or more) drive.
Do you have any documentation left on this controller other than the basic single sheet basic description (Interface..., encoding..., Tranfer Rate..., etc.)?
Thank you. I have spent a number of hours searching the 'net (google) but very little remains on this legacy controller.

Hi Paul, The problem is we want to update the 9100 so it can handle larger (newer) SCSI drives. Have you any suggestions for writing NCR5380 SCSI drivers for OS-9? We really don't want to try and save the old WD1002 card or it's MFM drives - the drives are way too old to be reliable... John :-#)# At 11:04 AM 20/09/2002 -0700, Paul Swan wrote:

John, I presume that if you plug in a new SCSI disk onto the 9100 there is a problem? The 5380 driver for OS-9 comes bundled with OS-9. The release at the time may not have been able to handle drives >2Gb though. As a first step, I'd suggest trying an older SCSI hard disk <2Gb in size and see if that works. Worst case it may be that the Fluke software itself is tied specifically to this drive configuration. Is the drive readable on standard 68K OS-9 System? Has anyone tried that? Regards, Paul.

">2GB"? This machine is 20 megs...supposedly won't handle a larger drive (like 40 megs) without drivers or firmware revision...drivers are all I hope it needs. I don't have a 68000 OS-9 system to experiment with. John :-#)# At 11:56 AM 20/09/2002 -0700, Paul Swan wrote:
