I recently bought a Mac II, 1Mb, 4 bit mono apple monitor, extended
keyboard.  I sold my Mac+, but kept my almost 2 year old Jasmine direct
drive 20.  I just connected it up and away I went.

However.  I bought a DPI 44R, their implementation of the Syquest 44Mb
removable cartridge drive.  They shipped promptly and the unit is very
quiet and compact.  My problem is that the Mac II refuses to recognize
the drive (with a cartridge installed).  The cartridges are supposed to
come preformatted and installed.

When I power up the drive, install a cartridge and wait for the drive
to come online, and then power up the Mac, I can see the access light
blink about once a second.  I presume that this is the Mac polling the
SCSI port.  (Oh yeah, the SCSI device number is set to 4.)

If I then load the floppy they supplied with the unit and run the
formatter, it recognizes that the unit is there at SCSI 4.  However, if
I then ask it to format (or install or initialize), the access light
immediately comes on and stays on and the Mac locks up.  I can
configure the Jasmine into the SCSI daisy chain before or after the DPI
and, so long as it is turned on, the system continues to operate
correctly but does not recognize the DPI.  I'm running System 6.0 on
the Jasmine, but 4.2 is on the formatter floppy.

Does anyone out there recognize these symptoms?

(BTW, DPI has been very sympathetic;  I've used several hours of their
800 phone time and they have already had the unit back and forth once.
They were able to make it work correctly with a Plus, SE, and a II.
It's driving me and them nuts.  But if it doesn't work soon I'm going
to have to take them up on their money back guarantee.)
