The HP-10BII Message #1 Posted by Larry Smith on 20 Aug 2009, 1:09 p.m. The 25 was a woodstock, the 65 a classic, the 42 a pioneer. What is the 10BII? What other calcs are part of this series? Lastly, what is the definitive list of pioneers?

Re: The HP-10BII Message #2 Posted by Larry Smith on 20 Aug 2009, 1:26 p.m., in response to message #1 by Larry Smith re: Pioneers - found a list on the web (of course) 10 minutes after posting this. As for the 10BII - the same source classes it as a Pioneer, but it doesn't match the Pioneer form factor at only five buttons across rather than 6. Is it really a pioneer? Are there any other calcs like it in the HP line-up?

Re: The HP-10BII Message #3 Posted by Gene Wright on 20 Aug 2009, 1:41 p.m., in response to message #2 by Larry Smith Thankfully, no. Especially if you're talking about the first version of the 10BII. Newest version is pretty good. Like the case, keys, colors. Original ... not so much.

Re: The HP-10BII Message #4 Posted by hecube on 20 Aug 2009, 2:58 p.m., in response to message #3 by Gene Wright Newest version is a charm to operate. It feels extra solid, key action is great and design is beautiful but I would prefer a dot-matrix display. CPU is a bit sluggish but you don't have calculate a space shuttle reentry with it so it's a non-issue.

Re: The HP-10BII Message #5 Posted by Mike Morrow on 21 Aug 2009, 10:30 a.m., in response to message #4 by hecube I purchased two at my local Walmart for $11 each. They were on some sort of clearance sale locally a few weeks ago. I was very pleasantly surprised by the apparent quality. I wouldn't mind having something similar in a scientific RPN calculator (especially if it handled complex number math).

Re: The HP-10BII Message #6 Posted by cyrille de Brébisson on 21 Aug 2009, 8:22 a.m., in response to message #2 by Larry Smith hello, definitely not a pionier, the 10BII is in a class of it's own, it is based on brand new source code (inspired from the HP100LX calculator) and has a micorprocessor only used by the 10BII (H8). the math part of the source has later been reused for the 33s/35s/17BII+ and 12Cplatinum version 2. regards, cyrille

Re: The HP-10BII Message #7 Posted by Scott Newell on 21 Aug 2009, 7:20 p.m., in response to message #6 by cyrille de Brébisson Cyrille, do you remember if the H8 used in the 10BII is flash or OTP? Thanks!

Re: The HP-10BII Message #8 Posted by Eric Smith on 21 Aug 2009, 9:20 p.m., in response to message #7 by Scott Newell Almost certainly neither Flash nor OTP. It's most likely masked ROM.
