The good news is that it looks like his CPU is 'mostly' working; and if the NXM is due to a fault on the CPU (e.g. bad bus transceiver sending the wrong address), that would be fixable (it uses 8641's). If the fault is in the DLV11-E (and not just misconfiguration), depending on where the fault is, he might be out of luck with that card; it uses DC005's for transceivers, which of course are unobtainium now. Still, QBUS serial interfaces are not rare. And overall, progress is being made! :-) Noel
