Yes and no.  The LATCC system didn't use the Raytheon or DCC display 
system--it used one built by Plessey.

Because of having to design, build, code for, and test a new display system.

In the 9020 days there only 20 ARTCCs in the US.  Besides which NAFEC had I 
forget how many 9020s: an A, a D, an E, and a simplex A at least.

There are 21 ARTCCs today, through the addition of Anchorage.  See 
http://www.ama500.jccbi.gov/factbook/ click on Current - July 2001, click on
Air Traffic, then move down one page for a list of ARTCCs.  Guam is listed 
with the ARTCCs, making 22, but as the footnote says, it's still a CERAP.  I
thought they were going to make Honolulu an ARTCC but I guess not.
