At some time some RISC manufactures headed toward ECL technology expecting
higher performance.  Unfortunately it was an extreme technology smashed into
dead-end.  Besides awesome multiple chip configuration, R6000 demanded an
extreme electronical characteristics which could not be achieved by stock off-
the-shelf components.  Then, RC62xx caught by severe manufacturing issues
was never sold well on market...
