How does the DM42 accuracy compare to other calculators ?

[BarryMead]

Swiss Micros wisely changed their claim about the calculator's precision which now reads.
"Most precise calculator on the worldwide market - second to none!"

This is now a true statement, since the WP-34s, and the calculators needed to run newRPL are no longer sold on the worldwide market. They have been discontinued as new devices, and must be purchased on eBay or other off-market sources.

I started tinkering with newRPL vers 1001 on my HP-50G. I am very impressed so far, but have only just started to learn to use it.
