A little bit off topic perhaps, but the Aug-1987 HP Journal covers the HP-28C/S and also explains why RPL was chosen:

The HP-28C firmware was developed in a year by a small
team using the RPL operating system and language (see the
article on page 21). The use of a highly structured language
was necessary for the implementation of symbolic mathe
matics, but also yielded a significant increase in productiv
ity compared with previous products, which were coded
entirely in assembly language.

Very good paper, I think it deserves a more permanent link, so I put it here:

http://hpgcc3.org/images/Documents/Wickes.pdf

It's not linked from anywhere else but this forum.
