Does anybody have any information about a 68000 based microcomputer made by Gould called the Gould 9540? I have recently purchased one so that I could play around with things like memory management (it has an MMU similar to that on a SUN-1, supposedly,) or operating system "stuff" in general. My problem is that it came with, effectively, no documentation. (I bought it second hand, and Gould never marketted the beast, hence no formal documentation.) It has a 7 slot Multibus cabinet with a CPU card, a serial IO card, a couple of memory cards, and a Disk Controller card. The inforation I am looking for is anything abut its MMU, what peripherals are mapped to what interrupt vectors, etc... Perhaps all I need to know is info about multibus protocols. I don't know. If somebody out there knows that "All serial IO on a Multibus is mapped to Interrupt Vector 3" or something like that, please let me know. Less probable, if anybody has evered tinkerred with one of these, please send me some mail. Thanks. __________________________________________________ | | | Patrick Doyle (617) 253-3261 (msgs) | | MIT, E40-358 or 225-8467 (home) | | (617) 253-4231 (work) 410 Memorial Dr. | | wpd@athena.mit.edu Cambridge, MA 02139 | | ...{decvax,ihnp4}!mit-eddie!mit-athena!wpd | |________________________________________________|
