[Coco] Looking for Datasheet (WD2412PH)

[Andrew]

All:

Its a 28-pin DIP IC made by Western Digital in 1982 (according to the 
copyright on the chip). I assume that it is some kind of floppy or hard 
drive controller? I tried googling, have come up with nada so far..

I purchased two today from a local suplus dealer; paid a buck or two, 
IIRC. I am just interested in finding out what it is, and how to 
(potentially) use it.

Any help would be appreciated - I am going to continue searching on 
Google...
