I don't think there is any question about it. Perhaps the low end of the
4300 line is pushing it, but the 4381 was fairly serious. Anyway, the 4381
has just as much RAS as the big machines, and in the mainframe world,
that is pretty much what counts.

$2M for the whole system (DASDs, comm controllers, etc.) is reasonable,
