In response to the question: >Our impression is that the error pin on a transputer stays set even after >the processor has been reset, and does not clear until code is loaded - >is this really the way it works?? The error pin is directly connected to the processor's error flag. If it is high then an error, e.g. arithmetic overflow, divide by zero, array bounds violation or software setting of the flag has been detected. Once set, the flag can only be cleared by the "testerr" instruction and IS NOT cleared by a reset. This is so analysis can detect which processor caused the error. Hope this clears up a few points.
