Thank you for your interest in "Customize Your HP-28".  This is a
standard reply - if you need more details or are interested in another
book please feel free to write again asking for those details.

CUSTOMISE YOUR HP-28 is a book of information, tips, programs, and
other details about the HP-28C and HP-28S calculators.  The first two
chapters take the reader through ordinary HP-28 operations, including
an explanation of RPN, and tips to make use of your HP-28 easier, and
better suited to your own requirements.  Chapter 3 explains the
SYSEVAL command and gives many examples of its use, most of them not
available from HP.  Chapter 4 expands on this information, explaining
how SYSEVAL can be used to write machine language programs. Chapter 5
shows how an HP-28C can be made more like an HP-28S, by the addition
of extra memory, by speeding it up, and by programs which do some of
the things already built into the HP-28S.  There is also a program to
let you use your HP-28S or HP-28C as an electronic notebook.
Appendices provide extra information, such as bug descriptions, a list
of machine language instructions, and a list of differences between
the HP-28C and the HP-28S.
