[cctalk] Re: RQDX3's: Lessons learned.

Thank you, good information. Found this from Midwest systems. They were a solid reseller back in the 1980's and this is probably the best first person vendor supported info on jumper settings for RQDX3's. READ BEFORE INSTALLING DISK DRIVE 2/89 RD54 MAXTOR * WARNING: This disk drive has been hardware formatted for an RQDX3. Do not attempt to format this drive on a MicroVAX using the Customer Confidence Diagnostics. The format is not compatible with this drive. If reformat is absolutely necessary, please contact Midwest Systems Technical Support Department first. 1. The RQDX3 being used MUST be inspected to determine its version, and the W23 jumper MUST be configured accordingly: (FAILURE TO DO SO MAY DESTROY THE HARDWARE FORMAT.) Version 3 Identification IF: Location 1: ROM 244E5, or 286E5; Location 2: ROM 243E5, or 285E5 THEN: at W23 jumper between post 1 & 2 only. Version 4 Identification IF: Location 1: ROM 340E5; Location 2: ROM 339E5 THEN: at W23 jumper between posts 1 & 2, and 3 & 4. 2. Depending on the drive version, set the white or blue unit select jumper (located in the rear of the drive on the printed circuit board) between C and 3 or 2 and 3 for drive zero (0).
