We just got a National Semiconductor 8MB Nubus memory board. Though this board can be used as main memory when under A/UX, it seems only usable under MacOS as a ram disk. We need a very large memory under MacOS (we cannot yet use A/UX, but that's another nasty story) and we were hoping that 16MB was achievable (8MB in SIMMS and 8MB NSC board). This incredibly large memory is needed because we are developing a very extensible vision system, and data space requirements are typically very large. A/UX could offset this problem with virtual memory, but features in MacOS which we use (i.e., some managers and other stuff) don't appear to be available in A/UX. (Is this true? That seems to me to be the concensus of what I've seen on the net. If not, please correct me.) In any event, even if we wanted to use the NSC board under MacOS, we need to get a ROM update to avoid the current limitation on Nubus address space... phil...
