For example, they have different C compilers. 2) The 800 series is a RISC like architecture with all of the portability constraints of that class of architectures. 3) The stack direction is different. 4) The 800 is a strictly aligned architecture. 5) The peripherials are different. For these reasons, supporting each of the HP series requires a software vendor to devote significant resources to development, capital equipment, QA, support and sales. regards, fletcher Fletcher E.
