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. http://www.applelinc.org Thankx, Ed 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. "Steven N. Hirsch" wrote: > Is this a "no brainer" (i.e. plug-in) conversion?
