Several years ago, I met a woman that worked at RS and she had a coco, the 
original HD interface and the hard drive. She actually used it for a while.
I tried to talk her out of it but she wouldn't give it up.

I still can't find the schematic for that interface. I'm sure it's here 
somewhere. While looking for it, I did find a diode I needed to repair my 
Onan.

As previously mentioned... it only had about three chips on it. The 
schematic was hand drawn(and not too well at that).
