[comp.sys.mac] Syquest cartridge disk problem

darryl@ism780c.isc.com (Darryl Richman) (09/02/88)

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.)

We just bought an Infinity Turbo 40 from PLI, and I seem to recall that they
were very specific in the way you could boot the system.  First, they required
that a cartridge be in the drive _before_ power up.  After you were powered up,
you could "throw" the disk icon in the trash, and then manually eject it from
the drive.

Secondly, the Turbo 40 is internally terminated, so depending upon the 
configuration of your system determined where it had to be placed.  The Turbo
40 was either the first or last SCSI device in the system, but nothing in 
between.  If you already have an external SCSI device that is terminated
(like your Direct Drive), and the Mac II internal drive is terminated, then I'm
not sure exactly what will happen.  That seems to me to be too many terminators
and you may have to end up cutting some resistors.

BTW, the cartridge drives are identical (Syquest).

Hope that helps.

What is the current street price of a Syquest cartridge?
Is it available from mail order houses.
What is the address of Syquest?

I am asking about the cartridge itself, not the drive.

P.S. I've had two Mass Micro Systems' Data Paks for three months, and
apart from a few minor problems they work great, both as a primary hard
disk and as a backup device. In addition, the customer support is 1st class
too. The termination though is a problem. I removed the internal terminator
and substituted with an external one, and it did not work! 

P.S. #2. Usual disclaimers.

I just bought some from Hamilton-Avenet for $100 each (Q1-99)
I got them within a week of sending them a check.

Hardware House (800-356-2892) has them backordered for $100. (Ordered on 6/26
and still not received.) They are a Mass Micro dealer.

They are in Cupertino, CA, if memory serves me right.
