You need to think about what the ROM does to make the cursor blink.  It has
a counter, it decrements it, and when it reaches a certain value, it makes
the cursor blink.  I wrote this little demo to demostrate how to make the
cursor not blink.  I found that setting it to 2 makes the cursor stay dark,
and a value of 1 makes it gray (at least on VTI).  Let me know if this
happens on the real calc.  Note that my method of calculating the interrupt
checksum is 9 bytes shorter than the method used by the examples on 86
Central (and by the ROM itself).  If you want if off, just disable it, or
play with the values (of course disabling it would be The Right Thing to
do).
