3.USE CAUTION WHEN ANALYZING DRI\J~ REVISION LEVELS. IN ORDER TO BRING R054 AND THIS REVISION MATRIX INTO CONFORMANCE WITH THE CURRENT DEC STANDARD 12 MANY DRIVE REVISION LEVELS HAVE BEEN REASSIGNED AND SHOWN ON THE TOP LINE AS TO WHAT THEY SHOULD BE. AS A RESULT REVISION LEVELS MARKED ON THE DRIVE MAY OR MAY NOT REFLECT THE ACTUAL HARDWARE REVISION AS DEFINED BY THIS DOCUMENT. TO ASSIST IN ANALYZING DRIVE REVISION LEVELS,REVISION LEVELS WHICH ~ERE ORIGINALLY MARKED ON THE DRIVE ARE INCLUDED IN PARENTHESES UNDERNEATH WHAT SHOULD HAVE BEEN THE CORRECT REVISION LEVELS FOR RD54.THE REVISION LEVEL IN PARENTHESES IS THE REVISION LEVEL YOU WILL FIND ON THE RD54 BAR CODE LABEL UNLESS THE DRIVE HAS BEEN REMARKED DURING REPAIR.

4. THE CHANGE IN RD'54 REVISION LEVEL FROM Al TO Bl REFLECTS A CHANGE IN THE COATING ON THE HDA BASE CASTING FRdM ZINC CHROMATE TO ELECTROLESS NICKEL. DRIVE REVISIONS At AND Bl ARE FUNCTIONALLY EQIVALEN1. THE ALPHA CHARACTER SHOULD NOT HAVE BEEN INCREMENTED WHEN THIS CHANGE WAS MADE. SINCE BOTH HDA'S HAVE A SIMIU:lR APPEARANCE~THE EASIEST WAY TO IDENTIFY HDA'S WITH THE OLD ZII'IC CHROMATE COATING IS BY THE DRIVE REVISION MARKING. DRIVES WITH THE 'OLD' HDA (ZING CHROMATE COATING) WERE ORIGINALLY MARKED Al AND MAY HAVE BEEN REMARKED WITH Cl OR C3 PER THiS DOCUMENT DURING REPAIR.

5.THE CHANGE IN 29-261133 ALPHA REVISION FROM A TO B ADOS A 2.32 K Ix RESISTOR m R61 IN PARALLEL WITH THE EXISTING RESISTOR AT R61. THE RESISTOR ADO IS REFLECTED FOR VENDOR PART NUMBER 113591385 BY A -22 FOLLOWING THE VENDOR ALPHA REV. LEVEL. POSSIBLE REVISIONS FOR VENDOR PART NUMBER 113591385 WITH THE RESISTOR ADD ARE C-22,D-22,F-22,AND H-22. SIMILARLY,THE CHANGE IN 29-813136-1313 ALPHA REVISION FROM A TO B ADDS A 2.32 K 1x RESISTOR AT Rol IN PARALLEL WITH THE EXISTING RESISTOR AT R61. FOR VENDOR PART NUMBER 113591355 THE RESISTOR ADD IS INDICATED BY A -23 FOLLOWING THE VENDOR ALPHA REV. LEVEL. POSSIBLE VENDOR REVISIONS FOR VENDOR PART NUMBER 113591355 ARE J-23, K-23, L-23 AN8 M-23. THE -22 OR -23 W'ILL BE MARKED ON THE J3 POWER CONNECTOR OR THE U43 (413 PIN DIP) CHIP. THIS RESISTOR ADO ADDRESSES A PROBLEM WHERE RDS4 INTERMITTENTLY FAILS TO SIZE CORRECTLY ,DURING A FORMAT OPERATION ON VAXSTATION 213013 AND MICROVQX 201313.
