Earlier versions of the MSV11-QA were shipped using a revision A etch and the documentation correctly showed the jumper configurations. However early in 1985 the MSV11-QA/QB/QC started shipping with revision C etch. The documentation at that point did not show how to properly configure the C etch. It is the intent of this MicroNote to point out the differences between the two modules and to explain the configuration of both the etch revisions. The two modules can be identified in any one of the three ways listed in the table below; 1. The location and value of the modules serial number. 2. The location of CSR and address jumpers and switches. 3. The module's designation number, stamped on the insertion handles will be different. 3A. Revision A modules will be labeled M7551-AA. 3B. Revision C modules will be labeled M7551-AA. SERIAL NUMBER LOCATION ---------------------- The two modules can be identified by the location of its serial number. The revision A module will have its serial number located in the upper right hand corner of the module as you hold it with the fingers pointing down or at you and the component side facing you or up as it would lay on a work bench. This serial number will be 5017547A1. The location of the serial number for revision C module will be on the component side also, but in the upper left hand corner. This serial number will be 5017547-01-C1. The attached diagrams of the revision A and revision C modules show the location of these numbers. 237 uNOTE # 031 Pag 2 of 9 JUMPER LOCATION --------------- The MSV11-QA revision A module allows for the selection of Block Mode DMA transfers, parity detection, and extended address parity error detection as well as CSR and address selection. The address selection includes two switches, one for the modules starting address and one for the modules ending address. The ending address switch is used to control the decode logic on the module as the same etch is used for 2MB and 4MB boards as well, each with different value memory chips to reach there designed capacity. The location and function of these switches and jumpers if detailed in the diagrams and configuration tables attached to the end of this MicroNote. The MSV11-QA revision C module does not allow for the selection of Block Mode DMA or for the selection of parity detection, these features are built into the module itself and can be used or not used through hardware/software compatibility. When used in a system that supports Block Mode the MSV11-QA will perform as a Block Mode device, when used in a non Block Mode system it will perform as a normal memory module without any decrease in that system's performance. When used with software such as RSX11 and using mixed parity/non-parity memories parity detection can be disabled through sysgen. The only functions that a user is required to configure to use the MSV11-QA revision C is CSR selection and starting and ending address. It should be pointed out that the two switches for starting and ending addresses have been flip flopped from the positions in which they were located on the revision A module. Once again refer to the diagrams and configuration tables attached to this MicroNote for location and function of these switches and jumpers. The following pages contain diagrams and tables for configuring the two versions of the MSV11-QA 238 uNOTE # 031 Page 3 of 9 MSV11-QA revision A Module Identification ----------------------------------------- +-----+ +-+ +-+ +-----+ | +____________|_|___________|_|____________+ | +-----------------------------------------------------+ | | | 5017547A1 <---------+- PRINTED CIRCUIT | | BOARD NO. | | | | | | | | | (COMPONENT SIDE) | | | | | | | | | | | | | | | | | | +-+ +-+ +-+ | ++ +---+ | +-+ | +---+ | ++ | | | | | | | | +--------+ +--------+ +--------+ +--------+ (A) MSV11-QA (ETCH revision A ONLY) MSV11-QA revision A CSR SELECTION --------------------------------- NUMBER OF JUMPER POSITION CSR REGISTER MEMORY MODULE R P N M ADDRESS --------------------------------------------------------------- 1ST IN IN IN IN 17772100 2ND OUT IN IN IN 17772102 3RD IN OUT IN IN 17772104 4TH OUT OUT IN IN 17772106 5TH IN IN OUT IN 17772110 6TH OUT IN OUT IN 17772112 7TH IN OUT OUT IN 17772114 8TH OUT OUT OUT IN 17772116 9TH IN IN IN OUT 17772120 10TH OUT IN IN OUT 17772122 11TH IN OUT IN OUT 17772124 12TH OUT OUT IN OUT 17772126 13TH IN IN OUT OUT 17772130 14TH OUT IN OUT OUT 17772132 15TH IN OUT OUT OUT 17772134 16TH OUT OUT OUT OUT 17772136 239 uNOTE # 031 Page 4 of 9 MSV11-QA revision A STARTING AND ENDING ADDRESS ----------------------------------------------- DESIRED SW1 SW2 STARTING ENDING STARTING SWITCH SWITCH ENDING SWITCH ADDRESS POSITION POSITION ADDRESS POSITION ----------------------------------------------------------------------- IN KBYTE 12345 6 IN KBYTE 12345 ----------------------------------------------------------------------- 0 00000 0 128 11111 128 11111 1 256 01111 256 01111 1 384 10111 384 10111 1 512 00111 512 00111 1 640 11011 640 11011 1 768 01011 768 01011 1 896 10011 896 10011 1 1024 (1MB) 00011 1024 (1MB) 00011 1 1152 11101 1152 11101 1 1280 01101 1280 01101 1 1408 10101 1408 10101 1 1536 00101 1536 00101 1 1664 11001 1664 11001 1 1792 01001 1792 01001 1 1920 10001 1920 10001 1 2048 (2MB) 00001 2048 (2MB) 00001 1 2176 11110 2176 11110 1 2304 01110 2304 01110 1 2432 10110 2432 10110 1 2560 00110 2560 00110 1 2688 11010 2688 11010 1 2816 01010 2816 01010 1 2944 10010 2944 10010 1 3072 (3MB) 00010 3072 (3MB) 00010 1 3200 11100 3200 11100 1 3328 01100 3328 01100 1 3456 10100 3456 10100 1 3584 00100 3584 00100 1 3712 11000 3712 11000 1 3840 01000 3840 00010 1 3968 10000 3968 10000 1 4096 (4MB) 00000 1 = off position (open) 0 = on position (closed) NOTE: Switch S6 of SW1 is not used.
