Hey Guys,
I've got a Defender MPU board giving me fits. Address line 6 goes high after about 20 seconds. I am not certian if this is just a symptom or the primary cause of this boards troubles.
I have socketed and thus rulled out the MPU buffer [74ls367] at 2F, I can also rule out the RAM as well as the ROM board. This still leave a LOT of chips touching A6.
Any ideas what might be causing this? Any suggestions to facilitate debugging? I would hate to shotgun all chips touching A6.
Thanks,
Saltbreez
