Does it load a prerecorded tape?  Can you verify that the program was saved 
to tape?  And recorded at the proper levels?  You might not have the volume 
set at the sweet spot for the CLOAD function.  Non-Radio Shack cassette 
recorders are often much more finicky than the Radio shack computer labeled 

Occasional garbage screen boots can occur if the start up timing is off in 
some manner that I have not been able to determine.  However if you are 
getting them more than 0.05% or the time then I would suspect a hardware 
fault.  Normally, you should wait more than 10 seconds after powering down 
before attempting to power up.  Less than 10 seconds might cause a garbage 
screen boot too.
