TRS-80 Model 16 hard drive questions...

I just acquired a TRS-80 Model 16. It came with an external hard drive; model 25-1025, labeled as a "Tandy 10 Meg Disk System". It's a considerably smaller unit than the usual TRS-80 hard drives I've seen -- it looks like it would normally hold a half-height 5.25" MFM drive. Unfortunately, the drive enclosure is empty. I'm not well-versed in the area of TRS-80 drives, so I have a few questions: - Is this drive actually compatible with a Model 16? The limited info I've found seems to hint that this was for a Tandy 2000 or 1000 system. - If it is compatible, what kind of drive goes in the enclosure, and where can I find the proper cable to connect it to the Model 16? (The enclosure has a 20 pin "Data" and a 34-pin "Control" connector on it, looks like a standard ST-506 configuration, while the Model 16 has a single 50-pin connector.) - If the drive isn't compatible, anyone have a compatible one for sale/trade? :) I'd like to try to get Xenix running, I have the installation floppies -- just need something to install it to. I actually work with a guy who ported the Xenix kernel to the Model 16 back in the day, I thought he'd get a kick out of seeing a running system again... Thanks, Josh
