Matthew...

Before you actually spend any money looking for docs and technical
specs, check out Motorola's online web site (I think both 
http://www.motorola.com  and http://www.mot.com work) ...  They have
a "request form" where you can order their data books.  Some of them
are listed as "not free" -- but I have found that if you put a
request for it in on the "free info request form" they will usually
send it to you anyway ...  Start with the 68HC11 Reference Manual
(number: M68HC11RM/AD).  Then after you've decided which version of
the processor you want to work with (example: A8, D3, K4, F1, E9, etc)
They have a "Technical Data" book for each version, usually under
the number MC68HC11xx/D where "xx" is the chip version.  They also
have pocket programmers reference guides (don't have the number on
me for them at the moment) ...  But this is a very good place to
start -- and it won't cost you anything getting there...  From that
point, you can checkout info about the evaluation boards they
offer as well as their assemblers...  I personnally prefer the
AS68xx assemblers written by Alan Baldwin at Kent State University
over the motorola freeware assembler -- they allow a lot more
flexibilty and a standard across several other processor assemblers.
(And that is the assembler I targetted my 68HC11 Disassembler
program that I wrote to work with) ...

Good luck...
