Also when you are doing a sum of numbers, but want access to the running sum (Entering a check register, for example) it was handy to have all the possible pending operations completed.

The Calc mode is not that bad, but I never found a real interest in it. On my HP-71, I usually prefer the immediate mode to do simple calculations.
The Calc mode has one (big) limitation related to sums, you have the impression that you can do an arbitrary long sum, as in RPN, but you actually can't, the sum is limited to 96 characters (the length of the HP-71 input line). You have the break the operation in several parts.
