[Coco] Floppy hardware...

Yes I changed the FD502's weird power supply connector for a regular one and it worked fine. 

Make sure that when one disk is selected, they all spin!

Good evening!

I'm having a devil of a time building a complete 2xDSDD 5.25" floppy system for my CoCo 3. I've got a complete one-drive FD-502, and a complete one-drive FD-500 (with the 26-3029 controller).

The FD-500, I discovered, only has a TEC FB-501 180K SSDD drive.
The FD-502, while it has a Mitsumi D502 360K drive, has unusual power connectors – not the standard 4-pin Molex, and it doesn't match the 4-pin mini-Molex found on 3.5" drives. The two-drive-bay enclosure has support for a second drive, but the included power connector is the same odd 4-pin that doesn't match a mini-Molex.

I bought a Chinon FZ-502 off Fleabay, which should be a 360K drive. It's got a standard large 4-pin Molex power connector.

Is the pinout on the power connectors in the FD-500 and the FD-502 the same? Could I install the Chinon into the FD-502 case by cutting out the odd power connector and splicing in a spare 4-pin Molex?

Don't even start me on the fun I had mistakenly buying what was labeled as a 360K TEAC drive on Fleabay and discovering what arrived was actually a 1.2MB TEAC-55GFR.

Fun stuff.
