| Running Diagnostics on the CDC 1700 Simulator | |
| ============================================= | |
| 1. Overview | |
| The diagnostics system (System Maintenance Monitor) is available from | |
| bitsavers.org as bits/CDC/1700_Cyber18/20100517/SYSTEM17_SMM_DIAGS.TAP. The | |
| simulator is able to boot this tape and has successfully run the following | |
| diagnostics with some caveats (for more detailed information see | |
| pdf/CDC/1700/SMM17 at bitsavers.org). | |
| In some cases the diagnostics fail to run correctly on the simulator | |
| for various reasons: | |
| - Some tests require hardware modifications or special cabling | |
| - Some tests perform timing checks which are difficult to implement | |
| in the simulator without further documentation or access to the | |
| diagnostic source code | |
| - Some tests check for features which are not implemented in the | |
| simulator. E.G. The disk controllers write Checkwords (CRC) for each | |
| sector written but the documentation does not specify the CRC | |
| algorithm in sufficient detail to allow the simulator to correctly | |
| simulate the feature. | |

| 2. Running diagnostics | |
| Detailed information on running the System Maintenance Monitor can be | |
| found at bitsavers.org in "pdf/cdc/1700/smm17". Here is a sample test run of | |
| the COMmand test (test 01), a CPU instruction test, using the default settings | |
| for running the test: | |

| that SMM uses a private bootstrap and we have to load that into the simulator | |
| by hand (User input to SMM17 is marked with "<==="): | |

| 3. Scripts for running SMM17 | |
| These scripts allow SMM17 to be run with various test features | |
| enabled. All of the scripts assume that a bootable SMM17 tape image is | |
| attached to mt0. | |
| 3.1 Basic SMM17 boot sequence | |
| echo Loading SMM17 | |
| echo | |
| set cpu sstop | |
| set mt0 locked | |
| boot -S mt0 | |
| 3.2 Use Buffered Data Channel #1 for tape access | |
| echo Loading SMM17 - Uses BDC #1 | |
| echo | |
| set cpu sstop | |
| set mt0 locked | |
| set dca interrupt=F | |
| boot -DS mt0 | |
| 3.3 Load MBS and use non-interrupt driven TTY output | |
| echo Loading SMM17 | |
| echo - MBS loaded | |

| 4. Notes on specific diagnostic tests | |
| MBS (Monitor Based Subroutine package) must be loaded for tests 0F | |
| and 4B. | |
| Test 0F (BD2, 1706/1716 Data Channel Test) requires a 7-track tape | |
| for section 4 (relies on the controller masking the output to 6-bits). | |
| Test 0F (BD2, 1706/1716 Data Channel Test) gets an error 0004 with | |
| Q set to 001C! The problem seems to be related to returning 7-track | |
| status in Director Status 2 (if I disable setting IO_ST2_7TRACK | |
| everything works correctly for sections 2 and 4). | |
| Test 4A (MTX, 1731/1732 Mag Tape Test) hangs while writing to the | |
| TTY. The source listing (60411400C...) does not match the code | |
| loaded from the magtape image. | |
| Test 4B (PET, 1732-2/-3 Mag Tape subsystem test) can only be used if | |
| the mag tape controller type is set to 1732-3. The test can access | |
| the controller in 2 modes; programmed I/O which only works up to | |
| 800 BPI and DMA (called DSA) which works up to 1600 BPI. In programmed | |
| I/O mode the tests complete successfully. In DSA mode, the test | |
| fails during the first read from tape (writes work successfully) with | |
| a timeout waiting for "end of operation". My current hypothesis is | |
| that the controller asserts "end of operation" when all of the data | |
| has been transferred to the CPU but delays generating an interrupt | |
| until it has processed the CRC at the end of the block. I would need | |
| to look at the test source listing before making any changes. | |
| Test 7A (MDC, 1733-2 Cartridge Disk Controller) passes most test. | |
| The seek timing test fails - I don't want to debug this without | |
| source listings. The checkword test fails since we don't store the | |
| checkword data in the emulated storage and it is not clear there | |
| is sufficient documentation to be able to construct a valid checkword | |
| on the fly. | |
