Hitachi DK239A-65

A much later but still fairly interesting pre-IBM buyout Hitachi laptop
drive. OK condition, I have another example in better condition. (with
correct initialization)
This one likewise seems to have a unique track layout - It might be just staggered surface sequential, or something of a combination of surface sequential and head sequential layouts. I may never know!
