"for some reason"?  Perhaps the fact that Phase IV was announced at the same
time that the DECSYSTEM-4050 (earlier DECSYSTEM-2090), code name "Jupiter",
was canceled?  It was only the size of the LCG customer base which forced
Digital into continuing hardware development until 1988 and software development
until 1993.
