CORRECTION: Add the new CCS module (L0008) to the Assembly Documentation. IN-PLANT EFFECTIVITY: Jun 83 FIELD EFFECTIVITY: Retrofit all VAX 11/750 and 11/751 Systems to System Revision Level 5. The minimum acceptable Revison of the spares in stock are: L0003 Etch Revision "C" Module Revision "F" and L0003 Etch Revision "D", Module Revision "F", L0004 Etch Revision "D" Module Revision "K", L0004 Etch Revision "E" Module Revision "K", L0016 Etch Revision "B" CS Revision "B" and L0008 Etch Revision "A" Part Revision "A1". QUICK CHECK: For Systems with the system halted, and the power applied, examine the System Identification Register (SID) and verify that the contents match page 2 of this FCO. A revised FCO was released on 14 September 1983 which supersedes the original release of 22 August 1983. It provides the following changes: On pages 9, 17, and 26 the Part Number BE-T538A-DE was changed to BE-T538B-ME. The DEC on-site labor charge will be the time required to install and test the FCO at the then current hourly rate.

L0004 Module: - Corrects the lost device interrupt problem, - Permits the use of all the vendor parts in the QVL,- Controls the crystal voltage when the toy battery isn't installed. L0016 Module: - Corrects the problems with refresh logic which can occur on power uo with six or more M8750 arrays. (This was part of revision 5 and may already be installed). 11/750 and 11/750 Systems - Replace the L0005 CCS module with the L0008 PCS module. (This was part of revision 5 and may already be installed). QUICK CHECK: For the L0003 module, E4 is a 74S00. For the L0004 module, a Jumper is installed between E46 Pin 1 and 2. IN-PLANT EFFECTIVITY: APR and MAY 84. _ DOL, 11750-R0007, VAX 11750 DEC 84 PROBLEM: 1.System Problems, Symptoms, and Solutions corrected by the VAX-11/750-R0007 are: A. Microcode "INSQTI" Stale Cache Data/CMI-Invalidate Problem. B. TB Parity Errors Machine Checks, due to TB RAM Soft Errors. C. UDA50 / L0004 VMS "HANGS". D. PCS750: Microcode updates that are difficult/expensive to implement via ROM changes to L0005/CCS. E. System ID Hardware Rev changes were difficult with backplane jumpers. 2. VAX 11/750 Module Problems, Symptoms, and Solutions with FCO-R0007 are: A. Problems with L0003 / Memory Interconnect (MIC) Module. B. Problems with L0004 /Integral Unibus Adapter (UBI) Module. C. Presence of a L0016 CMC MS750-C Memory Controller Module Power-up refresh Bug. IN-PLANT EFFECTIVITY: May 84 FIELD EFFECTIVITY: Retrofit all VAX 11/750 and 11/750 Systems to System Revision Level 7. The minimum acceptable Revision of spares stock are: L0003 Etch Revision "C: Part Revision "J1". L0003 Etch Revision "D" Part Revision "J2". L0004 Etch Revision "D" Part Revision "M1". L0004 Etch Revision "E" Part Revision "M2". This FCO incorporates the following ECO's: L0003-TW0004, L0003-TW005, L0003-TW006,L0004-TW006, L0004-TW007, L0003-TW008, L0016-SH002, 11750-TW004, 11751-TW004. QUICK CHECK: L0003 - E109 Pins 4, 5, and 6 are grounded, and the E4 is 74S00; L0004 - E11 is a 23-656A2-00. This FCO is a supplement to the original release of 10 July 84 and provides the following changes: On page 49, a Problem/Symptom statement was added. Additional supporting text (pages 49 thru 60) to the original FCO was also added. The DEC on-site labor charge will be the time required to install and test the FCO at the then current hourly rate.

Patchable control store is not loaded at boot time. 2. UDA50 boot ROM code does not allow enough time for RA60 to spin up after power fail. 3. ROM code for TU58 does not allow enough time for TU58 to initialize. 4. Massbus boot ROM code has wrong hex code for RP07 drive. FIELD EFFECTIVITY: Retrofit all 11750 systems to allow loading of PCS on power fail on all systems. This FCO incorporates ECOs: L0011-005, L0016-003, and L0022-001 and changes the system Revision to "8". QUICK CHECK: L0011 - E81 is 23-E41A9-00 L0016 - E44 is 23-E41A9-00, L0022 - E48 is 23-E41A9-00. This revised FCO supersedes Rev A released 23 April 1987. It corrects the parts list for brady markers, page 2; corrects the module Min. Revs page 3; shows correct module # (L0016) in Fig. 2, and corrects the module Revs., step 18, page 7.
