Kimbal/Piano disk

[Joe & Penny Goss]

Murry,
I called the store and they are looking to see if they have the test
program.
As the store is 100 miles from me it may be a few weeks before it is posible
for me to try what you and the rest have suggested.
Thanks all for the imput you may make a hero out of me yet <G>
