- I also have a ROM 01 GS with a DMA SCSI card, 44Mb SyQuest and a 40 Mb hard
- drive (MiniScribe mechanism). Sure, you have to make sure you don't have
- excess termination - but that's always been a "given" for multiple SCSI
- devices. I have internal termination on the hard disk, which lives at the end
- of the chain, and the SyQuest was always externally terminated. My boot order
- is determined by the SCSI id (ie. the hard disk boots first if it is powered
- on).

- I haven't actually checked, but I do not recall ever seeing this problem.
- On the other hand, I normally keep a cartridge in the drive - is there any
- particular reason that you don't? There were potential problems before ProDOS
- 8 v2.01 with too many partitions/devices, but that's not normally a problem
- any more.

- It always works first time for me! Are you sure you have the latest SCSI
- driver/manager files, ie. from System 6 disks? The drivers that shipped with
- the card have been superseded.

-
- Not only have I been using a SyQuest successfully, I have recently been loaned
- a SCSI 1.4Mb floppy drive to "play with". While there are one or two hiccups
- (I have no specs of any sort!), it basically works fine with the DMA SCSI
- card. I have even managed to partition a 1.4Mb floppy disk! I'm inclined to
- think that the DMA SCSI card handles removable media just fine! (OK, I haven't
- tried a floptical drive yet - anyone want to donate one....?)
-
- BTW, the interface card on the SCSI floppy drive has markings of 'CATSCO
- 679-0707-001', with ROMs marked 'SFC 04' and 'SFC 10'. Has anyone ever heard
- of these boards? (For some reason, I recall the word 'TORCH' on the card as
- well, but I couldn't find it when I just looked.)
-
- >Thanks for any advice!
-
- Why do I have the feeling that you might have a flaky SyQuest drive or
- interface? I had some severe problems with my first SyQuest - which turned out
- to be the drive itself!
