We are looking into replacing our instrumentation computer (an ailing DEC PDP 11/23-Plus) with either an MSDOS or a Mac II (no flames) system. We specifically require high speed A/D, D/A and TTL I/O. National Instruments Co. makes boards that will do A/D, D/A etc. that conforms to the NuBus standard. I have the following questions? 1. What is the NuBus standard (IEEE-?) 2. Can an add on card generate max. priority interrups (every 20 msec) to the 68020 on the Mac II motherboard? 3. Is it possible to write interrupt service routines (for a user program) that coexist with the windowing scheme, et.al. on the Mac II. Do you need an assembler or can you write it under a high level language? 4. Are there any good C compilers for the Mac II that are fairly bug free? Thanks for any information, Tim Takahashi Center for Visual Science University of Rochester Rochester, NY 14627 rochester!ur_cvsvax!tim
