have. The Apple cards are no longer made or supported; but, you may be able to
buy one at a swap meet.
The Sequential Systems RamFAST has DMA plus an on-board cache of either
256kB or 1MB, making it the fastest interface available. RamFAST has a full set
of utilities in ROM, so, it's easy to set up, too.

Apple Hi-Speed SCSI card users need to remember that these cards normally
do not supply termination power. (RamFAST does; but, not the Apple Hi- Speed
SCSI card.) To work properly with the GS, a Zip drive connected to the Apple
Hi-Speed SCSI card requires either another device that can supply termination
power, or requires a hardware hack on the Apple Hi-Speed SCSI card to provide
the termination power.
Note: The Apple Hi-Speed SCSI card termination power modification is detailed in
the Hard Drive and SCSI FAQs (file Csa2HDNSCSI.txt).

005- How do I install a Zip drive?
The main Zip installation step is plugging it in. The drive uses DB-25
connectors and, so, most likely, the cable will plug directly into your
interface card with no need for an adapter. In case you need an adapter for an
older 50-pin plug, these can be obtained from Alltech.
If you already have other SCSI devices, the one currently plugged into the
interface can plug into the Zip. Or, the Zip can be plugged into a hard disk,
CD-ROM, etc. at any point in the chain of SCSI devices.
Set SCSI ID Number- Every hard disk, CD-ROM drive, etc. on your SCSI chain
needs its own ID number (0-7). While most devices are flexible and will allow
you to choose any available ID, Zip gives you a choice of two: 5 or 6. If you
are using an Apple Hi-Speed card and you already have a hard disk, you'll have
to set the Zip to 5 in order to continue to boot off of your hard disk (which
needs to be 6). The RamFAST is somewhat more flexible in that it doesn't take ID
7 for itself and will allow you to boot f
rom any SCSI device.
Set Termination- Another consideration is termination. If all you have
connected to your SCSI card is the Zip Drive, then you should set the switch on
the back to turn ON the termination. If you have other devices that come after
the Zip, then you should set it to OFF. (Actually, the Zip presents a light
termination load and can be left with termination ON whether or not it is the
last device.) The last device in the chain (the one farthest from the
interface) should always have termination set ON.
Hardware-wise, that's it. In all likelihood, your setup will work fine. If
not, you can get help from experts at Alltech, post a question on
