This memorandum is a notification that Delta Tau
will no longer be able to conduct repairs on any versions of the obsolete MCC
and SMCC controllers, or of any product that contains them. While we have
in many cases attempted to repair these boards since their obsolescence
several years ago, our increasing inability to get replacement components
has reduced our success rate in these repairs to the point where it is no
longer worthwhile to either vendor or customer to attempt these repairs.
Remember that these product families date from the
early and middle 1980s, respectively. Delta Tau has committed significant
resources to supporting these products for longer periods than are the norm
in the industry. However, we must now focus our resources on our newer product
families – the PMAC, Turbo PMAC, and upcoming Power PMAC families of
controllers, accessories, and drives. We continue full support for these
newer families of products.
