The WDI (Winchester Drive Interface) was Cromemco's first hard disk controller. It was early on in the era before it was clear what disk interface format would predominate. This controller was built specifically for the 7700 series IMI drives (8" drives , a Z2-H or HDD11/22 ).

Cromemco WDI

The controller was used in their System 1 (Model CS-1H). I have no further information on this controller board. I would like to try it out if I could find a hard drive. If you know of one please let me know. Also I cannot locate the manual. If you have one I will place it here for all to see.
