We have an IMSB011 board runing on SUN3/110, which has a transputer and a C004 crossbar switch together with some other stuff. Our system is configured such that the transputer boots through the VME bus, using C012 and C004 in between. We use EXPRESS as the software environment, in which transputers are treated as nodes, and communication between nodes are handled by the EXPRESS kernel. We also have a number of other transbuter placed in INMOS item box, that we want to link with the transputer we have on B011. Problem: We want to replace the C004 with a pre-wired 84-pin header, for a fixed hardware configuration. We know how to hardwire the transputer links to P2 expansion. We also know that if we were to use C004, Link3Out, and Link3In (D1, C4) would be connected to C012 LInkIn and C012 LinkOut respectively. What we could not figure out from the manuals is how to connect the transputer's Link0 to the C012 Link Adapter. There is no connection between the C004 and the transputer's 0th link, according to B011 manual page 25. But the transputer would be booting from this 0th link if we were to use C004. If you did this kind of replacement or do know how to do it, please send the information to : ozkan@vuse.vanderbilt.edu Thanks in advance.
