works fine: 17b, 17bii
can't save erroroneous equations: 19bii

I don't have those other machines to test. The plusses, as you know, I gave up on a long time ago.

Agree the Plusses are a waste of time with the solver, though the 17BII+ Silver remains my daily driver for finance, which in my case never needs the solver....

I will take on testing the others and report results here in the next week or so.

FYI:
the 27S acts the same as the 17BII, which is as expected.
the 17BII+ acts the same (allowing erroneous equations to be saved) but does not produce correct results, both as expected
