Right for the HP-65 but absolutely not for the HP-67, which had 26 permanent storage registers vs. 20, and 224 fully-merged program steps vs. 224 non-merged steps. All in all, the 67 was about 3x-5x more capable than that sorry clunker, which was DOA, IMHO.

Speaking of which, shortly after the 41C was released, a wealthy client asked me to create a long, complex program for him, to be run on a TI-59 he'd just acquired for the task. I couldn't bear the idea of writing and debugging the program in that bothersome, third-rate programming paradigm/hardware so I convinced him to toss it aside and get an HP-41C instead (plus the card reader and all 4 single-density RAM modules available at the time) and then I would write the program for him.

He complained somewhat because of the total expense but eventually agreed, so I created the program per his specs (had to extensively use synthetics and every trick in my sleeve to make it fit) and in the end, after three iterations, he was very pleased and made a huge profit using the program.
