Hi PA-Riscers, Does anyone of you have references/URL/opinion.... on interoperabilty purpose ? The systems I would like to be able to interoperate are : - Linux x86 - Linux PA-risc 32bits - Linux PA-risc 64bits - HP-UX 11 64bits I already know the STK: http://devresource.hp.com/STK/ But it does not cover all the possibilities of interop.. I'm just looking for pointers & references ... Thanks in advance for your help. Nicolas HP
