That is the original Apple SCSI card (not the "High Speed" one).  The
ROM is revision C, the last version for that card.

The revision C ROM supports non-removable hard drives and the original
Apple CD-ROM drive (CDSC).

A maximum of seven partitions (spread over all drives) are supported.
You must use ProDOS-8 2.0.1 or later to be able to access more than
two partitions (if the card is in slot 5, and you have no disk
controller card in slot 2, then you will be able to access four
partitions with ProDOS-8 1.2 through 1.9).

The partitioning software should have been supplied with the card.
This is Apple's original HDSCPARTITION program.  There are two major
versions: the old one only works with the original Apple card, and
only supports two partitions.  The newer one only works with the Apple
High-Speed SCSI card, and supports two or four partitions.

The disk that came with the original card also includes a very old
version of the Backup II program and a SCSI disk Verify utility.

There is at least one third-party partitioning utility (Chinook SCSI
Utilities) that can be used with the card, but it is not available any
more (which is a great pity - it is an excellent program).

The shareware program "SCSI Hacker" might support partitioning - it is
so long since I saw it that I can't remember what it did, exactly.


You could also get someone else to partition the drive for you.  It
should be possible to partition it on a Mac, or on an Apple II with an
Apple or RamFast SCSI card.

If all else fails, E-Mail me.
