Well the USA kit changes the controller IC. to a WD 279X, this is the Proper
way, but don't know how they get over the Motor ON command,
The other way is the one that the Germans came out with is to Change the
Clock to the WD 1770 controller IC, but this can be hit or miss as the
IC is not ment to run with a 16 Meg HZ clock, also you have to have a switch
to change the clock back, or the sence line from the drive to control
the clock...I would like to try this but I will have to borrow a drive first
no piont in buying a drive if it does not work !!!
