We have a Sun 3/110 with 4Mbytes of physical memory on the processor card, a SCSI disk card, and the ``spare'' slot in the three slot card cage taken up with a double height transputer interface card riding on a triple height adaptor. We're running SunOS 4.0, and as soon as we try and run NeWS 1.1 (a 3.5 binary) with a terminal window or two, the machine slows down to a crawl, paging for all it is worth. It gets a lot worse if anyone else is trying to use the machine. Similar, though less noticable problems occur with SunView, and my guess is that the problem is going to get worse not better with later releases of SunOs and the merged NeWS/X.11 server (some informed optimist may care to contradict me on this). Conclusion: we need more physical memory. After some initial optimistic stories about piggy-back memory cards which could be patched onto the SCSI card, the Sun sales people here in the UK now say that we cannot get any supported memory upgrade from Sun themselves. Anyhow, I suspect it is probably the most expensive way to do it anyhow. My thoughts have been turning to using/making a VME adaptor to give us extra slots in an external VME rack, but one solution that would be particularly nice would be a double height to triple height adaptor which had additional SunOs accessible memory (4M/8M say) *on board* ? Before we make an adaptor card with memory... (!), has any one out there heard of/can recommend such a product? Please post any replies to me and I will summarise to economise on net bandwidth! tim marsland, cambridge university engineering dept.
