Here are the results for the 17bii (and the 17b would be the same):

first run, .211327
second, .653794
third, .122201
fourth, .347348

So on the 17bii+, you must get .211327 and then .122201.

Yes, exactly like that.

It's interesting that the Solver in the original 17BII does work with SEED=0.

My HP-27S with serial starting 2825 (week 25 1988) refuses. Just returns 0 as result. I have to make sure SEED <> 0 first.

I wonder how many different versions of the Solver there is?
