In contrast, the TI-57 takes around 2 seconds to shift 50 steps (when using the "Ins" key). Not sure how the HP-65 does that so fast (or the TI-57 so slowly). Maybe it is a feature of this carousel architecture.

I wouldn't put too much value in using any of the TI Majestic line for performance comparisons. They are basically junk machines with low accuracy algorithms and horriffically slow speeds. Put one side by side with the earlier 2nd gen machines (SR-50A, SR-51A, SR-56, etc.) and run the forensics. Not only are the older machines much more accurate they are much faster and responsive. Like driving a sports car compared to a lorry.

Good point. Probably the precision was plenty to, say, solve a Physics problem, the forensic test being somewhat of a pathological case. But the slow speed and the unresponsiveness, in some situations, was infuriating

This was my second calculator by the way, the first one being a TI-59. I just thought it would be fun to see what could be done within those 50 steps. Also it was really inexpensive, around $30, by that time.
