                                Notes+Zipdrive install instructions

This update will work with your existing 100Mb Zip Drive or can easily be updated to the 250mb Zip Drive. 

It is recommended that you do not full format or full cleanup your 100mb disks with the new operating system. 
It will make your disk unreadable.  This is the only flaw we have found in the update.

+++++++++++++++++++++++++++++++++++++++++++++++++++++
If you wish to update your Zip to a 250 version here are the instructions:

CHANGING OUT THE 100MB ZIP DRIVE FOR A 250MB ZIP DRIVE ON THE SP-808

Obviously: Disconnect the power supply and all other cables from the 
SP. Observe the usual precautions about electrostatic etc.  

***IMPORTANT*** You must use the internal IDE/ATAPI Zip250 Drive. 
Use of any other drive type could damage your SP. 

As you disassemble the SP, keep the screws in three separate piles as 
you remove them. Prepare places beforehand for all three sets so you 
don't lose them or get them mixed up.

Turn the SP over and rest it on something soft and pliable, like 
several towels, so that the knobs on the panel are not subject to 
unnecessary pressure.

(1) Remove all the screws in this order:
      (a) Removing the SP's bottom plate:
Remove the 13 screws on the bottom of the SP. Do not remove the two 
screws in recessed holes at the top; these can stay put. Don't forget 
the interior screw just above the middle rubber foot at the bottom. 
Note that not all holes have screws in them (at least on my unit).
Lift off the bottom plate; it should slip off easily. Put it aside in 
a position allowing you to remember which way it fits.

      (b) Removing the Zip-drive housing/frame from the inside of 
the SP:

[I found it easier to remove the power cable and ribbon cable from
the 
old Zip drive itself if I first removed the screws holding the 
Zip-drive housing/frame to the inside of the SP; it's just easier to 
get a grip on the cables.]

Remove the 5 screws attaching the drive housing/frame to the inside
of 
the SP (2 on the right, 3 on the left; the screw on the upper left is 
a little hard to get to if you don't have small fingers. When you've 
removed these screws, the housing/frame still won't come out all the 
way because the cables are still attached to the Zip drive inside it.

      (c) Removing the Zip drive itself from the drive 
housing/frame:
The Zip drive itself is attached to the drive housing/frame with 4 
screws, all on the top of the housing. Remove these screws and put 
them aside. The Zip drive will now be loose, but because it still has 
its two cables attached, you can't lift the Zip drive all the way out.

(2) Remove the two cables connecting the old 100 drive with the SP 
innards:
        (a) the power cable
(You will want to reattach it to the 250 drive the same way it was 
attached to the 100, so leave it in a position that makes that easy
to 
remember.)
      (b) the ribbon connector
(Same as above, though the fit inside the SP is so tight, this 
connector will remain pretty much in the same position.)

(3) Remove the old 100 drive from the drive housing.

**********************************************************************

(4) Put the two drives side-by-side for comparison and install the 
jumper/shunt into the 250 drive to set it to Master just the way it
is 
already installed in the 100 drive. The drive comes from the factory 
set to slave.

On the back of the Zip drive, between the ribbon-cable port and the 
power-cable port, there are three rows of two pins each.
If the Zip drive is lying on its back, the power-cable port will be
on 
your left, and the ribbon-cable port will be on your right. The three 
rows of two pins each will be between those two ports.

You'll see that the first row of two pins on the left is covered by a 
little jumper/shunt. This jumper should have come with your 250 Zip 
IDE drive (mine came in a little ziplock plastic bag).

If you're unsure, you can hold the jumper/shunt up to the one on the 
back of the 100 drive you just removed to see how it will fit onto
the 
two left-hand pins on the back of the 250.

Slip it onto the two left-hand pins on the back of the 250 to cover 
them. Press firmly till it is seated. This sets the Zip drive to 
Master. The backs of the two drives should now look the same.

**********************************************************************

Now the whole process is exactly reversed:

(4) Slip the new 250 drive into the drive housing/frame with the
cable 
ports to the back.

(5) Reconnect the two cables to connect the new 250 drive with the SP 
innards (a bit easier in the following order):
      (a) the ribbon connector
      (b) the power cable

(6) Screw all the screws back in (in this order):
      (a) to secure the Zip drive itself to the drive housing (4 
screws on the top of the housing)
      (b) to secure the Zip drive housing to the inside of the SP (5 
screws on the bottom, 2 on the left, 3 on the right)
      (c) to secure the SP's bottom plate back to the bottom of the 
SP (13 screws; the one with the washer goes at the top left)
