	Four: T, Z, Y, X

	T would duplicate as the stack dropped. X was the display after
operations (during data entry it was hidden)

	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.
