Moldy Oldies Message #1 Posted by Michael Meyer on 25 Mar 2011, 7:02 p.m. Well, a first for me. I bought a cheap HP-11C in a calculator lot for $16, hoping it would look better in person than in the photo. This time, it did not. It does, however, work fine. So, being badly in need of restoration, I took it completely apart. I've seen dirt, blue corrosion, green corrosion, etc., but seeing a calculator full of black mold? That's a first for me. I'm surprised it worked... the mold was everywhere! Time for a major bath, this time also in bleach, a first for me.

Re: Moldy Oldies Message #5 Posted by Michael Meyer on 25 Mar 2011, 10:25 p.m., in response to message #4 by Jim Yohe It was pretty gross. This was the first time I've used a heat gun to remove the keyboard faceplate and display plate. Sorry I didn't get photos. Picture little black spots and patches all over the circuit board, tape, display holder...everything. Yuck.

Re: Moldy Oldies Message #9 Posted by Michael Meyer on 26 Mar 2011, 1:39 p.m., in response to message #8 by Walter B What a crappy deal.

Re: Moldy Oldies Message #10 Posted by Randy on 26 Mar 2011, 2:12 p.m., in response to message #9 by Michael Meyer It's dead mold. It's more common than you think for units that get left in really damp or wet basements and tropical climates. Sometimes they'll have the smell but not the fuzz. Right fine incubators ;-)
