Do MEiKO machines have switch chips /\ do these prevent reproducible results? Yes, MEiKO machines do have switch chips. Yes, there probably are situations when they give different results for several different runs of the same program with all other things fixed. However, I did some quite extensive testing on our 70 transputer multi-user MEiKO system and even did some of the tests (which involved 16 or sometimes 32 transputers and were both compute and communication bound) a number of times and got invariably identical results. Even with other people booting, using and releasing transputers presumably at different times in different ways. My results were timed by looking at the transputers on-chip clock at low priority. >Michael Bane Warren
