This just keeps getting better. It seems the failed EEPROM chip in my logic analyser left a parting gift: it spiked the D4 and A9 lines on its way out. In other words, it's killed half a dozen bus transceivers (74F244 and 74F245), and probably the two MCM6206 high-speed RAMs as well... Does anyone have any Motorola MCM6206 series parts to hand, preferably in the J-lead surface-mount package? The parts installed now are MCM6206DJ35, but other (faster) speed grades should be fine too. I need at least two of these, but preferably four or five so I've got spares for future use...
