I have a (mad) friend who wants to stick some third party boards into an AT bus Apollo (something weird like a 1553 bus interface gizmo originally used in a "real" PC/AT). What are the best sources of information for such an undertaking (device drivers required, Apollo-reserved interrupts, memory map problems, etc.)? Anybody out there got any good war stories?

You will want a copy of the "Writing Device Drivers with GPIO" manual. The SR9.7 GPIO release tapes come with a number of sample drivers which are installed in the /domain_examples directory. Apollo has these "CPU configuration" worksheets (actually little cardboard cards) which list the reserved interrupt lines and device addresses for each of the different CPU types and the various standard Apollo devices. You can probably get a copy from your field service personnel. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter@eddie.mit.edu krowitz%richter@athena.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
