Keywords: Hardware Message-ID: <8217@brazos.Rice.edu> Date: 26 May 90 12:54:30 GMT Sender: root@rice.edu Organization: Sun-Spots Lines: 18 Approved: Sun-Spots@rice.edu X-Sun-Spots-Digest: Volume 9, Issue 183, message 9 I have read here about the SLC, and have seen Suns graphic announcement running on a SS1-GX, showing off the new workstation details. I seems that the new SLC uses 4Mbit SIMMS for memory, and it comes in a base configuration of 8MB, expandable to 16MB. The way I calculate it: 8 MB is only 16 bits x 4Mbits, and that means a 16-bit wide data path. The minimum memory you can use for 32-bit wide data with 4Mbit chips is 16MBytes... If the data path is only 16-bits, how much slower is the system going to be on memory transfers (1/2?), besides, what happens when you upgrade to 16MB, do you keep the 16-bit bus, or does it go to full 32-bits? Anyone know details/answers about this? Gil. P.S. : what is the Cache size on the SLC ?...
