Hello to any 8086 experts,
Basically I just want to see some signs of life from my board, but all I get is garbage from the address and data lines. Which means somewhere I have entered garbage.
I noticed that ALE never goes high, which makes my think I have a physical problem, improper design or mis-wire.
Please, any ideas why ALE line is low? Attached is a snap-shot of my logic analyzer going off the ~5Mhz clk, code, and schematic file.
Thank you
