Yes, the mechanism swap is a 'no brainer'. There is nothing special you will
need to do to transform your IIgs 800k into a superdrive there are only 9
screws and 4 plugs. Of course that assumes you are using the Sony superdrive
mechanism which is identical in physical specifications. Other mechanisms
will work, but may have issues regarding disk insertion and lack of ejection
options. I will assume you have the correct mechanism and that you know how
to work a scredriver. I think I'll put thsi up on the club web site and
finish the 5.25" mod page.

Thankx,

The step by step:
1. Turn off the IIgs and unplug the 800k drive, and separate it from any other
drives that may be attached. Find a flat work space and get a #2 phillips (+
cross point) screwdriver.
Remove the plasic case:
2. Place the drive upside down and remove the 4 screws from the bottom.
3. Lift off the cover and set it aside. Note that you may need to wiggle the
wire out of the U shaped groove at the back to free the cover. Note the
position of the cable in relation to the cover.
4. Grasp plastic top cover and the metal drive housing, slide the drive
towards the back of the top cover. If you look down the sides of the drive
housing, you will see four metal tabs come out of platic slots. Once clear,
lift the metal drive housing up and forward then set it down.
5. Note the two sets of wires attached to the back of the drive. One has a red
plug, the other is black. Remove the two plugs from the back of the drive by
pulling strait out. Once removed, set the top case aside.
Remove the mecahnism from the steel housing:
6. Turn the drive over and remove the retaining screw that holds the back of
the housing and cable in place. The cable is attached to this piece of
housing so do not pull it off yet, just lift it up and out. If you look down
inside, you will see the multicolored wires of the cable go into a black
plug. Reach inside and pull this plug strait up, freeing the cable from the
drive. Set the cable and housing piece aside.
7. Looking isnide the freshly exposed back side of the drive, you will see a
grey cable that goes from the circuit board to the drive. Pull the grey cable
out of the back of the drive mechanism. Be careful as the other end is
permanently affixed to the circuit board.
8. Remove the 4 screws along the sides of the drive. Slide the 800k
mechanism forward and out of the housing. Note that it is suspended in the
center of the housing by some metal tabs. The new mechanism will fit in the
same place suspended in the housing.
Congratulations, you have removed the drive, and that was the hard part!
Wasn't that easy?
Installing the new Superdrive mechanism:
9. Remove the drive shield form the 800k mechanism, it just snaps on. Gently
seperate and lift the drive shield from the back end of the drive. Note the
little metal hooks towards the front of the shield that hold it down there.
Place the 800k mechanism aside and label it as an 800k mechanism.
10. Put the drive shield on the Superdrive mechanism by hooking the front and
snapping the back end down. It should fit exactly as it did ont he 800k
mechanism it just came off of. If it does not fit, you may not have the right
superdrive mechanism or you may need to ignore this step.
11. Slide the mecahnism into the steel housing and secure it with the 4 screws
previously removed.
12. Plug the grey cable into the back of the mechanism.
13. Plug the drive cable back into the circuit board and allign back panel of
the metal housing. Secure that with a screw.
14. Flip the drive over and place inside the top of the plasic case. Make
sure you pull the red and black plugs towards the back and are not pinned
under the drive. Shift the drive mechanism towards the back of the case and
it should drop down. Then slide it forward to lock the tabs into the plastic
slots. Examine all four metal tabs and be sure all four are in the slots,
repsition as necessary.
15. Put the red and black plugs into their respectively colored connector
sockets at the back of the drive. (red to red, black to black.) Then tuck
the wires down inside the case so they lay flush or parallel to the sides of
the drive housing to ensure they do not get pinched when we attach the bottom
cover.
16. Lay the bottom cover on the drive and slide the cable into the U shaped
notch in the case. Wiggle the case a little to seat the bottom platic case to
the top. If all has gone well, it will fit perfectly. If it binds or doesn't
just go into place, remove the bottom piece and figure out what is not in
place.
17. Put the last four screws into the bottom of the case.
18. Plug in the drive and test it.

Is this a "no brainer" (i.e. plug-in) conversion? Any docs regarding
this floating around?
