If it is the mini module, you drop the bottom cover and there is a head lock near the front. There is a spindle lock to stop the drive from rotating that is on the HDA that is integrated into the static tab assembly that touches the center of the spindle. This requires a phillips head to remove this strap, and then rotate the spindle till the tab engages a raised round slot on the spindle, blocking it. you then replace the two screws to leave it blocked. I think the 96mb unit has a similar system, but we only used the sealed hda's. Jim

I have the CDC9448 service manual in front of me. I believe this is what was called a 'Phoenix' drive To lock the heads, first remove the top cover from the drive (screws on the back IIRC). On top of the positioner is a metal bar, held down by a screw at one end. Near that end there's a pin sticking out from one side of the bar. And a pin sticking out from the other side at the other end of the bar. Remove the screw holding the bar in place and engage the pin near the mounting hole with the hole in the head carriage. Then screw the bar back to the positioner frame. The idea is that the bar will then lock the carriage in the home position. The pin at the other enf of the bar is used to hold the carriage at the right position for head alignment. It's used when the drive is spinning -- moving tyhe heads out that far with the drive stopped will do a lot of damage. -tony

In order to do that, I would need : A scanner Someting to connect it to (a PC?) Some way of storing the data (CD writer?) A house extension to house it And most importanty, somebody to maintain it. Unless you know of a properly documented scanner that connects to a classic PERQ, that is :-) -tony

The problem then becomes the one of convincing me to stand in front of a copier for a few days (this manual is not thin!). More serieously, is there any collector in the London (England) area who could scan it? The reason I ask is that I may have _2_ copies of this manual. I would be prepared to lend one out for scanning if I can find both of them (I don't want to be without the manual -- I have one of the drives too). But I'd rather not trust it to the postal 'service'. -tony
