I'm looking for some sort of hardware handbook for the SPARC chipset (or,
at least, someone's implementation of it), which would include an
architecture summary (instruction set, register usage, addressing modes,
etc.), pinouts, and timing information.  I've tried calling LSI Logic and
Cypress Semiconductor (twice...), and in all instances was told "we'll
send you the book".  Of course, no such book ever arrived from either
source.

Does anyone know which, if any, of the other SPARC implementors will
*really* send me technical data about their chips...?

Thanks,
--Pat.
