FOR SALE: HP28S calculator A great scientific calculator. It has a lot of keys, and it looks like a little book when you close it up. Seriously, folks, I actually am upgrading to an HP48sx, so this is a chance for all of you who want a good HP programmable calculator to get your hands on one CHEAP. ...how cheap, you say? ...how does $100 sound to you? Now, that price is pretty firm, but it WILL come with several useful books and the original box and manuals. The books include three short booklets on College Algebra, Vector and Matrix Calculations, and ...um, I forgot, and two Grapevine Publications books--two great books jam-packed with programs, "Utilities" and "Electric Circuits." So, talk to me! Michael C. Grant mcgrant@portia.stanford.edu

I have gotten a bunch of mail on the post about the HP 28S I have for sale. It seems I over-estimated what I could get for it. The following price (or something close) was suggested by a number of people. The calculator is in excellent condition. -------------------------------------------------------------------- Hewlett Packard 28S Calculator Owner's Manual (337 pages) Reference Manual (352 pages) Guide to Solving Calculus problems (90 pages) $120.00 or best reasonable offer (+ shipping) -- Mark M.
