I'm missing the two terminator resistors on a 1990 Maxtor 7080SR 80 mb drive.  They are 11-pin SIP (? I think that's correct).  Does anyone have any thoughts on proper resistance?  Someone had suggested 330 ohms and 220 ohms.  Does anyone know what the standard was?

Follow-up, and I should say I don't really understand what I'm asking, should they be bussed or isolated?
