HP 28S - Better than You Thought Message #1 Posted by Howard Owen on 16 June 2011, 3:24 p.m. "People could cheat on a math test with it and that is what it is known for. " http://cgi.ebay.com/HP-28s-Calculator-/260801635492#ht_540wt_1141

Re: HP 28S - Better than You Thought Message #2 Posted by Geoff Quickfall on 16 June 2011, 3:53 p.m., in response to message #1 by Howard Owen Wasn't the 34C the first with a solver? As for cheating, any continuous memory calc was good for that as long as you could get it by the TA's guarding the door! The 41C was great cause you could create a program to display "MEMORY LOST". That usually convinced a no-nothing TA that the calc was clear of programs. Of course, I really wouldn't know if that worked or not ;-) Then again, if you could write an RPN program to cover the formulae required for the exam, you usually ended up with them memorized in any case, (now that did happen to me so I really did memory loss the calc at the door, guilt and all that). Cheers, Geoff p.s. did I mention that I love my 41CL

not the first graphical calc Message #5 Posted by Frank Boehm (Germany) on 17 June 2011, 8:23 a.m., in response to message #1 by Howard Owen Well, I replaced my Casio fx-7000G with an HP 28C - that one was the first. Paid 199DM for the Casio and 444DM for the HP. Quite a bunch of money for a 15/17 year old :)
