This shows a failing test, sigh.
Initial test results
The CPU error register
Enter the following to show the CPU error register:
| Code Block |
|---|
>>>e/m 6
00000006 100101 |
The format of the error register is this:
...
which means we have the following bits set:
Bit | Description |
|---|---|
CIM PWR FAIL | This bit, when set to 1, indicates that the power to the machine has exceeded voltage tolerance limits for a period of 1.5 us or greater. |
ODD ADDR ERR | This bit is set when the program attempts to reference a word at an odd address. |
DATA TRAN | This bit monitors the DATA TRAN line of the CPU. When clear it signals that the processing is initiating a data transfer on the UNIBUS. |
This is a clear indication the power supply has a problem. As I measured the +5V lines and they were OK I assume for now that this will be related to the bad voltages on the other rails.
This error appears to cause the POWER MONITOR BIT FOUND SET error during the ZMSP memory test, but I need to validate that.
KKAAB0 (CPU and EIS)
This test got back to the console with the following:
