There are computerized keys. If you have modem access, call
TAXACOM at 716-896-7581. This is the Nat'l History Museum in
Buffalo, NY, I believe. They have programs such as ASKATAXA,
and a couple others. If it is more convenient, you can get
a couple from my bbs at 503-843-4214, but TAXACOM would have
the latest versions. They were not on the Internet last I checked.
Email me for the names--I can't look them up just now.
