SCSI DEVICES

The current driver works with most things SCSI, although we haven't
tried everything. Most SCSI hard drives have been tested -

        SEAGATE
        QUANTUM         best performer so far
        CONNER
        FUJITSU         also very fast
        MAXTOR
        NEC

We haven't found any drive not to work, but be wary of old devices. I
don't think ADAPTEC ST-506 to SCSI ACB4000 controllers work, but later
ESDI controllers may work. If anyone has access to such boards, I would
like to hear how they go.

Other SCSI devices will rely on SCSI direct (implemented in SCRAM 8/16
driver). The 8 bit has been tested with a Toshiba CD ROM using the CD-ROM
File System and works OK. I think SCSI tapes will work with appropriate
software. Let me or Will know if you encounter problems and we will
attempt to resolve them.

Most people will want to mount their drive on the SCRAM 2000 card
directly. Make sure you use standoffs to let air circulate between the
drive and the board. If you are rolling your own, you will need to make
cables to connect the drive to the board. In some cases you might be
able to use a spare power cable from the Amiga to power the drive, but
really it is more convenient to get power from the card.

MAKE SURE you don't get +5 and +12 switched, or there will be great
gnashing of teeth - yours not mine. It is sad to see a 500 Mb SCSI drive
shuffle off its mortal voice-coil in a puff of smoke.
