It's a good question as the Casio calculators of the time '78-'82 that ruled the roost (FX-50xP/FX-60xP) certainly didn't (I had an FX-602P until recently).

There was the hybrid CQ series with alarms/time (CQ-1/CQ-81) but they were of course not Scientific, but do fit the time period (well at least the CQ-81 does, the -1 was probably '76/'77). One would assume it would have been from this series?
