My dad had one on his desk where he worked. I would multiply all 9 times all 9 Whir whir whir. I can still hear the sound. Thanks for the memory.

ACC MULT means "accumulate when multiplying", results of several multiplications are added together without clearing the accumulator register.

Division actually worked just fine. The problem was it rolled over 99 in the counter register. This can easily be corrected by changing the position of the decimal point.

Red buttons on the counter register are carriage stop buttons. When you press one of them and push the carriage shift button continuously, the carriage will stop at the pushed red button.

I have one that is locked up, it was resistant to easy fixes. Someday I'll dig into it further

"But it doesn't do that, let's take away 80 here, *it'll roll the whole thing back to 9s.* " I love how you said the bolded statement

Just got one today. Mine is a few years older than yours. R / NR should ne to repeat / non repeat the keys, where the number keys stay locked down through a cycle.

the levers on the side are used to sync parts of the calculator together for certain gang multiply or division functions, see some internet videos re the "FACIT" electric calculators, should work in a similar way, also the "turn counter" - one of the registers you mentioned needs to be used to show answers in division, so one of the other levers also reverses this counter.

The little knobs below the keyboard are nothing more than decimal place/comma indicators, a visual aid for the user, as are the red sliding coursers on the carriage. They serve no other function.

+jedi1357 You are right. If you turn the dial, it will put a red marker between the keys to show decimal point. However, if you slide the dial toward you (it will shift slightly--maybe 1/8 inch), it will lock the keys to the right of the dial row.

Have you considered watching any of the dozen videos explaining how this works?

"...not going to make your bargains there anymore.." hehe, dude, I've been stopping by Weirdstuff for about 20 years. Last Saturday I found Alesis and Roland drum machines, Roland Sound Canvas, Alesis Microverb4, Kurzweil MicroPiano and other music gear that was mixed up with rackmounted network junk all for $7-$12 apiece. In the last few months, I bought a computer-controlled pipette machine for $10, a table-top tape drive (compatible with IBM 9-track format) for $50, a fully working (but unpopulated) HP 16700B logic analyzer/oscilloscope, half dozen ruggedized Neural ID vision computers, and lots of odd (failed) one-of-a-kind product prototypes.

what is the model and make of the calculator that you used to verify the division

It was a Texas Instruments calculator but the exact model eludes me. They sold a few different models in the same case design.
