HP 41C is acting up Message #1 Posted by Tracy Vermeyen on 8 Mar 2005, 11:44 p.m. I have a HP 41C that displays the PRGM ALPHA and Flag 1-4 annuciators when I turn it on or press the USER switch. The display goes back to normal when I press practically any key. Any suggestions on how to fix this? Thanks

This service, available at "www.fixthatcalc.com" for a reasonable price worked wonders for the used pre-1985 41C and 41CX I bought. -- KS
