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:

Sample test run of the COMmand test (test 01), a CPU instruction test. Note
|
|
that SMM uses a private bootstrap and we have to load that into the simulator
|
|
by hand (User input to SMM17 is marked with "<==="):

y is the number of register pairs to be displayed) it was successful. If it

terminates with A1 containing xxy8, the test failed and the remaining

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
|
|
echo - Non-interrupt driven TTY output
|
|
echo
|
|
set cpu sstop
|
|

|
|
set mt0 locked
|
|

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.
