TRS-80 Model 16 hard drive questions...

[Josh Dersch]

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
