Mr_Maniacal, I had success with these:

Mounted this CF-to-IDE adapter in place of my hard drive: https://www.amazon.com/gp/product/B0036DDXUM

Used this CF card: https://www.amazon.com/gp/product/B00NUB2TWI

Please note, there is a type of compactflash card called "CFast" and it is important that you do not buy one of those. It's a different kind of device and I don't think it will work in an empeg.
