All hail William Walsh for pulling this adapter out of obscurity!

Sigma Data QED/68 IDE Adapter

I'm not bothering with the component IDs on this- they're all PALs or simple logic chips.

I'll guess that this is a REAL simple-dimple IDE controller with a burnt-in drive table (like the one on the IBM MCA IDE adapter)

Went through the add a bit- it has LBA in it. I'll have to install this card and an IDE drive to see fer sure...
