Did you know the 2nd bathch of Spice calculators are more accurate?
In the HP-15C Advanced Functions Handbook, it details the issues with the accuracy of 3 raised to the 201 power. The first launch of Spice HP calculators in May, 1st, 1978, the 31E and the 33E get the answer of 7.968419661 E 95. The 32E that came out on July 1st, 1978 gets an answer of 7.968419664 E95. the correct answer would be 7.968419666 E95. This shows that there was a change in algorthims used from may 1st, to July 1st, 1978, and the later 32E is a little bit more accurate and closer to the correct result.
