[Coco] So, how do I make Drivewire go?

[Christopher Smith]

Since everyone else is talking about it, I thought I'd write in about my experience with Drivewire last week.  I thought I'd set up Drivewire and get the CoCo actually doing something.  Pulled the HDBDOS WAV file for the CoCo 1 from the cloud-9 web page.  Also installed the Drivewire 4 server on my Linux box and the MacOS X Drivewire 3 server on a different machine, just in case.  The cable, as far as I can tell, is correct.  I made it after this diagram: http://www.mediafire.com/view/c91gj67kw7q6yzu/CoCo_DriveWire_3_Serial_Cable.pdf

Anyway, I load up either Drivewire server, tell it to serve some floppy images, load HDBDOS off cassette, and everything looks ok but the only thing I can get HDBDOS to tell me about any disk device is "I/O Error."  It flashes lights on the serial interface when it tries to access the disk, but the server doesn't seem to do anything useful in response.  I'm afraid it's been a couple of days, but I remember seeing a lot of OP_NOP in the log.  Am I missing something obvious here?  How does one debug this stuff?
