At least one third of the UltraPenguin hackers did not have any SPARC
experience one year before. He learned SPARC assembly by looking at
the output of cc -S. This same guy is also responsible for Linux
having the fastest memcpy operations on the SPARC.

It would be much easier to get access to a merced machine.

The UltraPenguin team had to do some extensive hacks gcc/binutils to
get the thing up and running on the SPARC-v9 which is the 64-bit
extension of the SPARC architecture.

Porting the GNU gcc/binutils to a new platform is not a difficult
task. If 3 hackers could get the Ultra-64 port up and running before
Sun could port Solaris to their SPARC-64 chip, imagine what thousands
of Linux hackers can do with the intel 64 bit chip.
