360 360 xxx xxx TBG test failed. Third and fourth bytes (xxx xxx) indicate the address in the VCP code where
the error was detected.
340
--- --- ---
When the LEOs are in this static pattern the memory test is running and has not yet
completed; this is not an error condition.
340 200 000 000 No memory found or missing frontplane connector.
340 2nn xxx xxx Main memory failed. nn
=
01b to 12b depending on where in the VCP code the error was
detected. Third and fourth bytes (xxx xxx) indicate the 32-KByte block of failed memory.
341 000 377 377
ECC memory detected in A400/A600; ECC memory is not supported in an A400/A600.
(This error should never occur on an A990.)
300 200 000 000 No I/O cards in the card cage.
300 201 Oyy Oxx
More than one card has VCP enabled; yy and xx are the select codes of the enabled cards.
300 202 Oyy Oxx
Broken I/O chain; yy is the number of I/O cards found by polling; xx is the number found by
priority scan; the break will usually be found at slot xx
+
1.
300 203 000 Oxx Duplicate select codes; more than one card has the select code xx.
300 204 000 Oxx An I/O card at select code xx has a select code of less than 20b.
300 205 000 000 No I/O card has been enabled as the VCP interface.
300 206 000 000
Unexpected TBG interrupt.

an A990.)
300 213 000 000 VCP Speed Sense failed.
300 220 xxx xxx
} An I/O card at select code 20 through 77 failed self-test. xxx xxx is the address in VCP
where the error was detected.
300 277 xxx xxx
* The error codes for phase 2 of Test 2 are displayed on the upper 8 LEOs as 4 bytes of information using the
scheme illustrated in Figure 3-1.
