I wonder what this has to do with classic _computing_, but anyway I guess thrre's at least one microcnotroller in every CD player :-) Going the other way, there were certainly a few early external CD-ROM drives that wrre based on CD players. I have an old Philips here, it's a modified Philips CD player, to repair it you need both the service manual for the CD-ROM version _and_ the one for the CD player it was based on. I speak from experience... Of course all audio CD players are single-speed, which means if you want to try to take parts from an CD-ROM drive you should look at one that is a single-speed one. However, I've normally had more success getting parts for audio equipment than computer peripherals. Now to the fault. Every CD player I've worked on has had a simple rule : 'No focus, no spin'. When you insert a disk, or whatever, the following sequence occurss 1) The laser is turned on, and the laser power correctly set (via a feedback photodiode in the laser package) 2) The lens moves up and down a couple of times attempting to focus the laser on the disk. The exact fedback varies depending on the type of laser pickup assembly, Philips (the one I'm most familiar with) is somewhat different to most others. 3) The spindle motor starts. The speed of this is controlled indirectly if this gets too full, the disk slows down, if it is too empty the disk speeds up). Since this couldn't possibly work if the laser pickup was incapale of reading the its from the disk, the disk doesn't start until (1) and (2) are satisfied. So the fault might not be the motor at all. Converserly. I have had CD players using cheap permanent-magnet motors which have failed due to earing trouble or brush/commutator wear. If this is a simple permanent magnet motor (just 2 external connections), try disconnecting it from the rest of the player (desolder the wires if you're not sure) and apply a few volts to the motor terminals. See if it spins then. -tony
