bubble memory gone

[JCVineyard]

have any of you ever had to re-initialize the bubble memory on an old general Numeric T6 . The old VTL has been down for a while, and I can get into the control to write the bubble, I have no idea what needs to be inputed. there seems to be 6 3-digit codes. any ideas would be greatly apreciated.

This may help, I believe it was for the 6?
