Error Conditions

The power-on LED flashes rapidly during a failure, but the CPU LEDs are

unaffected. A failure condition while bit 0 is active is not likely. Active

states on positions 1 through 4 indicate which quarter of memory generated a

failure.

A failed location is repeatedly and infinitely read and written - even in a case

where the data eventually matches – until power is removed. This condition

allows for scoping the bad signals. The failed location is written and read

16K times in each power-on cycle. The processor reads and writes the point

of failure at maximum speed.
