I think, there is not the place where You can see whole history of RPN mode. You can fill a lot of stacks, but when You execute the operations, situation in stacks is changing and You can not see how looked stacks before operations. Only from last operation You can restore operands with [Shift], [+](Ans) or with Ans command.
