The "high profile 2031" is the same as the "2031", "high profile" was
added to the name when the "low profile" came out in order to distinguish
between them.
The 2031 has only one processor. The operating system has the same
structure as the 2040/3040/4040, but the one processor executes both the
DOS and controller functions.
