Hi All,
The Tabor board doesn't have a classic FPU with dedicated  FPRs found on most other PowerPC systems. It is replaced with a set of  SPE instructions which perform floating-point operations on the integer  registers. 
Important: The SPE unit can execute floating-point  operations very fast. We have tested a lot of programs with FPU  operations this year.
Tabor sound, 3D acceleration, and network work  without any problems on Debian PowerPCSPE. I'm very surprised about the  performance of this board.
Note: It is also possible to install a  normal PowerPC distribution of Linux on this board. The missing FPU  instructions are emulated for PowerPC programs by the Linux kernel.
Cheers,
Christian
