"I have been using the SyBA "SD-CF-IDE-DI IDE" adaptor (NewEgg Item# N82E16822998003)."

So "John Recommends!" :->.

Hi Neil,
 
as you have noted, most CF adapters out there have the IDE connector mounted in a way that is 'inverted' from our point of view,
The CF adapter IDE connector should have the locating bump on the component side, Most Don't.
John uses a adapter made by SyBa, these are available on Ebay if you search for 'syba cf adapter'
alternatively you can run a IDE cable out to a Startech 3.5" Drive Bay CF adapter as I have done, these work fine also.

I've ran into an odd issue with IDE card.

The card has been fully built out.

Without the CF adapters installed the boards as expected. I'm able to write to all 6 TIL311's correctly; probing around the board everything looks as I would expect; the drive flip flop works etc.

When I plug in a CF adapter the ID0..ID4 signals are pulled to VSS (8255 Port A PA0..PA3 pins, CF adapters pins 11,13,15,17 ). It's definitely the CF adapter pulling the 4 pins low. I have 3 CF adapters, all three do this; both CF positions on the PCB result in the issue.

I've swapped put the 8255 and the 74LS244s (U12 and 14). At this point I'm lost.
