Are you saying you don't have an MPI ?  If you do, the wireless pak 
shouldn't keep you from using your floppies, HD's, RTC, etc.  It just 
adds a wireless serial port.

I'm getting lots of bitbanger errors at the NOS 6809 L2 prompt 
(115200 bps bitbanger).  About 50% of my attempts to build a new boot 
disk result in a crash of NOS, sparklies and all.  Replug the USB 
serial adaptor, reboot the DW3 server app, and it usually helps.  Strange.

Latest news!  Finally, a partially bootable 6551 bootable NOS 
.dsk.  That is, I boot up the CoCo with CoCoNet Disk BASIC ROM, not 
DriveWire, type DOS, and NitrOS-9 should boot OVER THE AIR from the PC.

I just got as far as the CoCoNet boot module talking to my 
server.  It just requested LSN 0 and crashed, which was ascuallt 
GREAT news.  Why?  Because I forgot to preserve reg.U in a subroutine 
and was also referencing an ASCII decimal string using #direct 
addressing by oversight.

I just made some changes and will post my results as soon as 
something cool happens.
