Just use a sharp knife point to peel the feet off. They can be re-used if you are careful. Be careful of ESD. If you don't know what ESD is then don't open your calculator. There are two basic designs for the internals of your calc, depending on the vintage. Either way I would suggest using a can of compressed air to blast away the dirt. Be careful, your are on your own. John McVey jmcvey%hpbslq@hplabs.hp.com
