I don't have either of them spare, but it's worth knowing that as well as 
the Fort/Assembler module (which is the normal one), there's also an HP41 
emulator module which contains much the same Forth. No assembler, but 
with the HP41 emulation fuctions instead.

You can;'t have both of them plugged into the same 17 at the same time. 
Unlike most 71 modules, part of the Forth ROM is hard-addressed (has a 
fixed address) so the 2 modules try to occupy the same address space.

Incidentally I have -- somewhere -- the HP71 Forth Internal Maintenance 
Specification, which is the commented source to the Forth and Assembler 
programs, documentation on the dictionary format, and other fun stuff...
