Sigma Data IDE
@6405.adf Sigma Data IDE Adapter Driver diskette that shipped with the QED/68-XXXX

Finally figured it out! Duh, the QED-68 zip is the ONLY one on SIGMAs' site that has an ADF in it! I will diddle with OS/2 a little bit more.... I is intellijent. Yuk-Yuk.

All hail William Walsh for pulling this adapter out of the dustbin of history! 

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...
