I am buying an used HP28S. Althogh I have looked at HP-28S in shopwindow for many times, I have a few questions regarding this calculator that needs to be answered. -- 1) What and how many things come with a HP-28S (i.e. manuals, etc.) -- 2) I heard that HP-48S has a few different ROM versions. How manu HP-28S ROM version have there been? And what is HP's upgrade policy? -- 3) Is there anything that I should know, consider, and ask for before buying an used HP-28S
