Behold the WP-30S

[Gene]

1) Inv Trig - you are correct unless there is a very tiny -1 by them. Fortunately, the convention is so strong for that they *ought* to do, that I had not even looked closely. :-)

2) Re: Alpha - we were trying to avoid having to put anything on the faceplate and to make use of the 20b black background. It would be more noticeable on the 30b of course. What letters are used beyond the 2nd row for registers? Easy enough to put something on this to show those letters.

3) PART to MORE works fine too. Small change to the overlay.

4) What would CL_ALL do in the catalog ?
