| My solution?  I put a DS disk (formatted w/SpartaDOS) in the drive, then
| turn on the computer.  I get greeted with the familer "No Dos" message,

I believe that the same thing can be accomplished by merely pressing the 
reset key on the XL/XE computers.  That may not work for the 800 models
though as the reset is handled slightly different.
