The new units (HP28, 48, 49, 50, etc.) no longer use the 4-register stack; the stack is whatever is available in memory. As a result, the Roll instructions now need an argument for how many stack entries are in play. The HP50g has a bit of a sluggish response compared to the 48sx [which is not equivalent to a 48g]. Might be since the 48sx is still a SATURN hardware processor. The 50g is an underclocked (for battery life) ARM, running a SATURN emulator, with the emulator running the RPL/RPN user interface (there are packages that let one program in SYSRPL [which bypasses all the user level data checks, so if one knows the data on the stack is good, one can speed up subsequent operations], SATURN assembly, AND ARM assembly). For $20 or so one can get the HP Prime as an Android app. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
