Full Version: 71B Function Question

Is there any APPT capability on the 71B like there is on the 75 series?


Only if you write your own. There is no clock in the 71, only three countdown (or up) counters. You must write your own time entry and display functions, time keeping function, alarm setting and comparision, etc.

Why would they have SETTIME and SETDATE if there was not clock or time? They also have a Calendar section in the manual but I just did not find any mention of an alarm or appointment.

I also noticed that there is a ((*)) annunciator for alarm like there is on other calcualtors but it is marked as "future enhancement". I guess that function might have been planned but left off.

Oh well...
