Hello Netters! Here is a question for *REAL* hardware buffs... I have an application in which communication from a T414 transputer to a C011 link adapter could be suspect, so the transputer link must be programmed in a fault tolerant way using the reinit library's OutputOrFail.t, Reinitialise, etc. If I deliberately fail the system by pulling off the link to the C011, I find that communication can be re-establised on one transputer system we have here, but not for another one of identical circuit design. The layout of the two boards is different, but since they both function perfectly well with 'ordinary' occam programs, I can't see a problem here. The other difference is that the board that can restart has a T414 transputer marked as: (M) inmos B IMST414B-G17S 8729 NMN02K UK ...while the board that can't restart has XREL written in pink writing on it and a transputer marked... (M) INMOS B IMST414BG PRE QUAL 8617 F203 N6346HY MADE IN U.K. The network tester reports that it is a 15MHz device, even though it doesn't say so in the markings. Does anyone out there know of any differences between these two devices which makes the second one less able to restartB ? Thanks in advance... *************************************************************** * Chris Stops * * * Room A16 * Janet * * Main Building * ~~~~~ * * UMIST * cs@uk.ac.umist.electrical-engineering.nabla * * PO Box 88 * * * Manchester * * * U.K. * * * M60 1QD * * ***************************************************************
