ksrefRev2

This document, titled "KSREF.MEM for hardware REV 2" (with REV 3 changes included), is a comprehensive technical reference manual from DEC Marlboro, dated December 1978. It provides detailed information about the DEC KS10 system, covering its 8080-based console, the KS10 processor, various peripherals, micro-machine architecture, and debugging tools.

Key areas covered include:

• 8080 Console: Detailed overview of console operations, commands, error codes, booting procedures (including power-fail recovery), communication area, and console register contents.
• KS10 Processor: Descriptions of processor status words, memory management unit (UPT/EPT) layouts, I/O instruction formats, internal and external register bit formats, and ECC (Error Correction Code) details.
• Peripherals: Information on device addresses, interrupt vectors, jumper/switch settings, UART baud rates, and register formats for various devices like RH11, RM03, TM02/TM03, DZ11, LP20, CD11, and DUP11 controllers.
• Micro-machine: Low-level details on micro-code, including the HALT-status block, m-code field listings, dispatch ROM definitions, and micro-word bit assignments sorted by physical bit and function.
• Debugging: Instructions and information related to DDT (Dynamic Debugging Technique) commands and a UNIBUS adapter wrap-around test.
• UBA-RH11: A dedicated section detailing the read and write operations of the UNIBUS Adapter (UBA) and RH11 disk controller.

The document serves as a deep-dive technical specification for the KS10 system, essential for understanding its hardware, diagnostics, and low-level programming.
