This is what I've found. Hope this clears some doubts....

Universal and PC Alpha Microprocessors
There are two variants of most Alpha microprocessors manufactured by
a Digital Equipment Business. These variants were created in order to
enable delivery of
lower priced processors for systems that would compete in the emerging
Windows NT PC
>From a contractual standpoint, the license for Digital Unix explicitly
lists the Alpha
processor part types for which it is supported. Running the operating
system on a
non-supported processor is in violation of the software license. This
could subject the
user and potentially the company delivering the configured system to lose
the privilege to
use and/or sell this software.
>From a technical standpoint, the PC microprocessors only support a
limited set of memory
management options sufficient for Windows NT and some other operating
systems, while the
Universal parts support all of the memory management modes necessary for
OpenVMS and Digital UNIX.
In our manufacturing process, we will sometimes substitute the full
function processor and
mark it as a PC part in order to optimize our manufacturing costs. This is
the Universal part is a proper superset of the PC part and will be able to
be used in any
system designed for the PC part. However, since this is not always the
depending on this occurrence will be faced with an unreliable source of
supply. Any set of
parts may contain any number that will not run Digital UNIX or VMS, while
all will run
In summary: Our PC Alpha microprocessors lack memory management functions
running Digital UNIX and OpenVMS. In addition, using PC Alpha processors
with Digital UNIX
explicitly violates the software license for this product and will not be
we will at times mark full function parts as NT parts, this can not be
counted on and will
not be supported by Digital.
