PS/2 44-Pin Disk Controller [Thanks to Make Sakaki and chris@ship.net]
The Model 30(286?) HardDrive is an old XT IDE type drive. The connector to
the system-board is a ribbon cable that is not compatible to the "standard"
clone connection.

The HD requires +12V and +5V.
Get +12V from wire 40/42/44, and +5V from 30/32.
Get Ground from wire 34/36/38 and 24/26/28.
