hacking the hp 17bii+ Message #1 Posted by David Griffith on 27 Nov 2012, 2:33 a.m. I took a closer look at the hp 17bii+ and noticed that the display appears to be dot-matrix. Has anyone involved with the wp34s project considered porting their code to this calculator? I'd love to see an exacting replica of the hp42s come out of a marriage like this.

Re: hacking the hp 17bii+ Message #3 Posted by Walter B on 27 Nov 2012, 4:12 a.m., in response to message #1 by David Griffith David, that topic was discussed here more than once since the launch of the 17bii+ Silver. Tim confirmed it's a masked ROM design (or something similar - anyway: it can't be reconfigured) :-( But there may be a better alternative - stay tuned :-)
