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.RegardsDavid Fry

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.-Neil--
