![]() Although it would be interesting to see dedicated keys for TVM and other financial functions in any kind of future build/model. Here in Australia (me too!) it's hard to find, but a couple of years ago I was able to get 2 for $20 US each! One I kept as a 30b and the other I converted to a WP34S, which has lots of probability distributions (more so than any other machine anywhere, I reckon, thanks to Paul, Walter, Marcus etc.) The latter also has some TVM capability with the programs loaded into Flash RAM. It is more powerful than the 12C in that regard. It boasts >250 functions too, but also has trig built in and some programmability. Its simple layout and menu system is ergonomically underrated. The manual says it has >250 functions, but add to that the 7K memory useful for solver equations, and it can be turned into quite the versatile machine. I can't really do justice to the 17BII/17BII+ question, although I did plug the trig equations written for the former into the latter (Gerson Barbosa's) and these worked nicely (the L and G functions seem to be OK). Does anyone know where HP saw the 30B sitting in the hierarchy was it designed to replace something else, or was it going to be a continuing line? And why did they ultimately decide to discontinue it but continue on with the 17B? ![]() To me the 30B seemed like a more capable "do everything" (well, everything a finance/economics/business/accounting student might need to do) machine. Then the 17BII+ ought to be the top of the line, "do everything" calculator? But it doesn't cover the range of the inbuilt functions the other two calculators have (no break-even, no probability distributions for example, which the 10BII+ has) The 12C is my primary calculator for uni, partly because it's the only RPN calculator allowed, and partly because it's a very capable machine. The 12C holds a special place, the CFA no doubt helps, it's legacy, and nostalgia. Here in Aus one of our major university only allows the 10BII+ for business students and gives them for "free" to new students. ![]() To me it seems like 10BII+ is a student's basic, do most-things, algebraic calculator, and no doubt generates a lot of sales. Mind you this is from an accounting/finance students point of view, not from someone in STEM. I'm quite impressed by the math and statistics functions available. I don't yet have either of these calculators, but looking through the manual it looks like an incredibly capable machine, with many more useful inbuilt functions than the 17bii+/12c/10B. The other question I have is comparing the calculator to the 20/30B. I have noticed some loss of functionality coming from the 19B however. ![]() ![]() Looking through the manuals there seems to be little if any difference. I'm looking for some insight as to whether there were any functional differences between the 17bii and the 17bii+, aside from the solver (LET GET) which I am already aware of. Nice to have RPN back, I don't know how many times I've had to correct my inputs on the 19B.should probably try buy a 19Bii I guess! I do prefer the larger screen on the 19B, and it's initially a little strange to see that the menu keys don't quite line up with the screen. Initial impressions are that it feels instantly familiar, after having been using the 19B quite a bit over the last couple of weeks. Certainly I don't need another financial calculator, but it's nice to have. I received in the mail today a 17bii that I picked up for $10 AUD, in very good condition, and I'm quite happy with it. A quick question or two about the 17BII/BII+ and 30B. ![]()
