HP-92 financial calculator Message #1 Posted by Ed Sejud on 21 Apr 2006, 12:29 a.m. I have used an HP-92 financial calculator for almost 20 years. This is the desktop version of a 12C. One of the keys (the 0 key) now produces multiple 0000 with a single touch. I think the mechanical contact need to be cleaned. Does anyone know who can perform repairs on this model? Please advise edsejud@comcast.net

I think you can probably do it yourself. The 9x are relatively easy to disassemble, and you don't have to drill out any heat stakes. I scanned the service manual, and it's on the MoHPC CDs/DVD.
