================================================================================ Note 4.0 LSI-11/73 Upgrade Paths No replies JAWS::KAISER 300 lines 25-MAR-1985 09:15 -------------------------------------------------------------------------------- +---------------+ +-----------------+ | d i g i t a l | | uNOTE #004 | +---------------+ +-----------------+ +----------------------------------------------------+-----------------+ | Title: LSI-11/73 Upgrade Paths | Date: 28-NOV-83 | +----------------------------------------------------+-----------------+ | Originator: Mike Collins | Page 1 of 6 | +----------------------------------------------------+-----------------+ With the announcement of the KDJ11-A CPU module, there will be numerous questions regarding configuring the module into a current system. The purpose of this MicroNote is to address all possible configuration upgrade paths (within reason). Generally a KDJ11-A will be installed as an upgrade to a system built from components or DEC packaged system. In the case of a component upgrade it is assumed the processor is a KDF11-A and the boot mechanism is an MXV11-A with the MXV11-A2 Boot ROMs. System upgrades fall into 2 categories: 1. KDF11-A based systems and 2. KDF11-B based systems (11/23+ and Micro/PDP-11) There are 3 issues which must be addressed when considering a KDJ11-A upgrade. They are: 1. The Boot mechanism 2. 18 or 22 bit system 3. Single or multiple box system NOTE 1. In the following upgrade scenarios, the systems have been labeled as being Field Serviceable or not. A system which is Field Serviceable has a bootstrap which meets Field Service requirements. The requirement is that the bootstrap must execute an 11/73 cache memory diagnostic on power-up. There is no guarantee that the overall system will be Field Serviceable or that it will be FCC compliant. 2. Systems using CPU's other than the KDF11-A or KDF11-B (i.e. 11/03 systems) are not considered for upgrade. CAUTION: It is recommended that the AC and DC loading for the final configuration be checked for conformance with the Q-Bus loading rules. It is also recommended to check for overloading on the +5 Volt and +12 Volt Power Supplies. Page 2 For each system upgrade the following parameters are listed for both the 'Current' system and the 'Upgraded' system: 1. CPU 2. Boot Mechanism 3. System Size 4. Number of Boxes 5. Field Serviceable or not 6. Special Conditions COMPONENT UPGRADE PATHS: ----------------------- 1. Current System Upgrade 1 -------------- --------- KDF11-A KDJ11-A MXV11-A MXV11-B/MRV11-D with MXV11-B2 Boot ROMs 18 Bit System 18 Bit System 1 Box 1 Box Field Serviceable Upgrade 2 --------- KDJ11-A MXV11-A 18 Bit System 1 Box NOT Field Serviceable 2. Current System Upgrade -------------- ------- KDF11-A See upgrades for category 1 MXV11-A 18 Bit System More than 1 box 3. Current System Upgrade -------------- ------- KDF11-A See upgrades for category 1 MXV11-A (Memory Disabled) 22 Bit System 1 Box 4. Current System Upgrade -------------- ------- KDF11-A Not currently configureable with MXV11-A (Memory Disabled) DEC equipment. 22 Bit System More than 1 box This system is not currently configureable with DEC equipment.

Current System Upgrade 1 -------------- --------- KDF11-A KDJ11-A BDV11 MXV11-B/MRV11-D with MXV11-B2 Boot ROMs 18 Bit System 18 Bit System 1 Box 1 Box Field Serviceable Upgrade 2 --------- KDJ11-A BDV11 18 Bit System 1 Box NOT Field Serviceable Disable the Processor and Memory tests and also the BEVNT register on the BDV11. Upgrade 3 --------- KDJ11-A MXV11-A (with MXV11-A2 boot ROMs) 18 Bit System 1 Box System NOT Field Serviceable Check AC loading since termination was removed when the BDV11 was removed from the system. 6. Current System Upgrade 1 -------------- --------- KDF11-A KDJ11-A BDV11 MXV11-B/MRV11-D with MXV11-B2 Boot ROMs 18 Bit System 18 Bit System More than 1 Box More than 1 box Field Serviceable Use BCV1A and BCV1B expansion cables. Upgrade 2 --------- KDJ11-A BDV11 18 Bit System More than 1 Box NOT Field Serviceable Disable the Processor and Memory tests and also the BEVNT register on the BDV11. Use BCV1B cable set between 1st and 2nd box and the BCV1A cable set between the 2nd and 3rd box. Note: If in a 3 box system the expansion cable set lengths must differ by 4 ft. Page 4 Upgrade 3 --------- KDJ11-A MXV11-A (with MXV11-A2 boot ROMs) 18 Bit System More than 1 Box NOT Field Serviceable Use BCV1A and BCV1B expansion cables. 7. Current System -------------- KDF11-A BDV11 22 Bit System 1 Box Systems with this configuration were never shipped by DEC. PDP 11/23 PLUS SYSTEM UPGRADE PATHS: ----------------------------------- 8. Current System Upgrade 1 -------------- --------- KDF11-B KDJ11-A Boot is on CPU MXV11-B/MRV11-D with MXV11-B2 Boot ROMs 22 Bit System 22 Bit System 1 Box System 1 Box Field Serviceable Upgrade 2 --------- KDJ11-A MXV11-A (with MXV11-A2 boot ROMs) 22 Bit System 1 Box NOT Field Serviceable Must disable RAM on MXV11-A. Upgrade 3 --------- KDJ11-A BDV11 22 Bit System 1 Box System NOT Field Serviceable Must have BDV11 ECO M8012-ML005 installed. Disable the Processor and Memory tests and also the BEVNT register on the BDV11. Page 5 9. Current System Upgrade 1 -------------- --------- KDF11-B Not currently configureable with Boot is on CPU DEC equipment. 22 Bit System More than 1 Box Upgrade 2 --------- Not currently configureable with DEC equipment. Upgrade 3 --------- Not currently configureable with DEC equipment. MICRO/PDP-11 SYSTEM UPGRADE PATHS: --------------------------------- 10. Current System Upgrade -------------- ------- Micro/PDP-11 Same as 11/23+ rules, see category KDF11-BE 8, Upgrade 1. Upgrades 2 and Boot is on CPU 3 are not recommended since the 22 Bit System MXV11-A and BDV11 cannot boot the 1 Box system 5 1/4" media in the Micro/PDP-11. 11. Current System Upgrade -------------- ------- Micro/PDP-11 Same as 11/23+ rules, see upgrades KDF11-BE for category 9. Boot is on CPU 22 Bit System More than 1 box NOTE It is not currently possible to expand out of the Micro/PDP-11 while maintaining FCC compliance. 11/23 PLUS and Micro/PDP-11 system upgrades will require an EXTRA backplane slot to accomodate the additional boot module (i.e. MXV11-A,-B or BDV11).
