The top slot in the current PI can be used for either 2 half/high devices, or one full high, so no sheet metal (or other mods) are necessary. Of course, this doesn't do anything for the proposed 2 cpu's in a single chassis! On a related note, there has been some discussion of possibly providing an optional second SCSI bus on some future ESD (low-end) machine, similar to what was recently added on the IO3 board for the high end machines. Is this something that some of you might find useful/desirable? What other i/o features are folks looking for? (Don't bother complaining about pricing, I'm only interested in engineering related features!) Please reply via E-mail to olson@sgi.com, unless you think it is of general interest. I'm only soliciting opinions, not making any promises. I speak only for myself, etc., etc. -- Dave Olson Life would be so much easier if we could just look at the source code.
