There are a lot of things that the OS has to depend on that are *not* standardized in the VAX Architectural Manual. The I/O subsystem differs a bit between models; f'rinstance, UNIBUS interrupts are handled quite a bit differently between the 780 and the 750/730. Therefore, the architecture may be standardized but it still can take 6 months to get UNIX (or VMS, for that matter) running on a new implementation. (If it takes much longer than that, have a nice long talk with the implementors...) Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
