HP-65 accuracy error

[n1msr]

Well, I am one of the people who had an HP-65 restored recently (in 2023 after owning it for almost 30 years - it was a freebee back then).

I was caught out by this [in]accuracy quirk. On my 67 I have been able to use the 10^x function to help store/shift digits around in a register. I can multiply (or divide) by 10 explicitly to move a digit on the 65, but that seems cumbersome.

Interesting! But glad this post is here to confirm this 65 "feature" :-)

PS: the thing I find odd is that the 65 executes faster than the 67. Except I now have a teenix.org board in the 67, which has a turbo mode, so the 67 can be faster.
