Did you know the 2nd bathch of Spice calculators are more accurate?

I checked the result of 3^201 on more Spice models.
33C: 7.968419661 E 95 no accuracy improvement
37E, 38E : 7.968419664 E 95 with the improvement
Checked on both multicalc and nonpareil, a confirmation on the real machines is welcome.

The HP-38E seems to be the first with the accuracy improvement, although it was introduced at the same time as the HP-31E and 33E that don't have it.

BTW, it's a challenge to display the mantissa of 3^201 on the 37E...
