For anyone who is interested, "willtell.com" as posted will only operate
successfully on computers running at (or near) 4.77 MHz. To patch the 
program for higher speed machines, the following addresses must be 
altered (I'll give the commands in Debug format):

-e0152,f4,01
-e016f,f4,01

This works OK on my machine at home (AT&T 6300 with a V30 at 8MHz). For
those running at different clock speeds, a simple formula will give you
good numbers to substitute if the above don't work.

Compute [ 300*(your processor speed)/4.77 ] and convert this number to 
hexadecimal. Substitute this hex value for the "f4,01" above (remember
to swap low and high bytes). You may have to tweak the values a little
to get it right, but this should get you in the ballpark.

"Willtell" is a nice piece of work, but it would be nice to have 
the adaptability and flexibilty of VMUSIC for the higher speed machines.
