Looking for IBM 4869 5 1/4 drive or power supply

Greetings.

Anyone have one of these units for sale or have an extra power supply laying around you can sell? I'm interested in either the 360KB or 1.2MB drive.

On mine the power led flickers on and then off when applying power and when turning it back off, so I'm assuming it's the power supply. Ideas on how to test this PS?

Thanks

Still going through a carton of the things picked up way back when. Very handy things.

The flickering of an LED on power cycling may or may not mean something. Use a meter to see where the power appears or disappears. There's only +5 and +12--and you needn't have a drive attached when testing. That should enable you to determine if the problem lies in the PSU or the drive.

Hello Chuck(G),

I tested the PSU and it showed both +5 (actually slightly over 6V) and +12 (actually around 11.6V),and it held. I hooked the power cable and data cable back to the drive and the spindle moves slightly and stops but the power led still isn't on. I removed the original 5 1/4 drive and added a 1.2MB floppy, and still no evidence the drive works. I mean isn't the drive supposed to at least run and the drive in use light stay on until you turn on a computer it's hook up to? This is an OS/2 system and it doesn't show under the "Drives" icon. I have other computers with external 5 1/4 drives and I turn them on first then the computer. The drive keeps running until I turn on the computer and then the power on light at least stays on.

Any more thoughts, and I'll leave ya alone. ;-)

Thanks.
