Hi Bill!
I'm having great difficulty getting to web sites possible due to internet 
connections being down around the country, so if you could send me a copy of 
this utility disk for the CocoSDC, I would greatly appreciate it.

An extremely scary hack of Darren's routines above.  Warning: no checking of 
anything is done... don't overwrite your current selected ROM.  bad things will 
happen.  This will flash a straight, flat, ROM file from a disk to your SDC.

download the file sdkutils.dsk.
