Still working on this, once I finally found time to install the adaptors, a flaw was discovered. The particular models I found indicated slave support when I looked at them in the store. Unfortunately it looks like the PCB is shared with a dual slot converter, and they put the slave jumper on both. The back side has pads for a second CF slot, and the adaptor does nothing when it's jumped to slave mode. Time to settle on an online adaptor and have it shipped since I have 2 good 32GB cards in hand.
