Cleaning the board had no effect. Went back to the other one. I identified a failing row of chips and tried swapping some around bit after awhile anything above 128KW became glitchy. (I'll clean contacts tomorrow) Also...it seems I had a bad DELQA on the bus which probably wasn't helping.

It don't work? DMA works fine! However other tests and SCSI FIFO does not. Hmm. Ok. I assume you have CPU in slot 1, and memory in slot 2. Slot 3 is also Q/CD, Yeah. and after that (if I remember right) you have Q/Q slots. Have you tried minimizing the config to just the minimum required to test the machine? Yeah. I also wiped down the board a bit...it gave ECC errors before even doing memory access this time. Putting the project on hold until the board dries. (It's the board i'm 98% sure, the behaviour is different enough to not indicate any other boards. Either it'll work after this...or it'll look really damn clean!)
