Electrohome is still making their
Marquee series of projectors. These came out in 1992 as a high end 8
and 9” 1000 lumen EM focus projector. All have digital convergence, on
screen menus, and work exceptionally well. The M8XXX series designates
the 8” model, the M9XXX the 9” model.
The M8000 came
out in 1992, and was made through to 1995. It was rated at 1000 lumens
due to the slightly lower voltage high voltage power supply. Sets
pre-May 1994 did not have an internal hour meter, software changes post
June 1994 put one into the service menu.
The M8110,
M8500, and M8500LC replaced the 8000 in spring of 1995. The light
output was upped to 1200 lumens due to the new high voltage power
supply, the tubes, lenses and rest of the chassis was upgraded some
over the M8000 model, but a number of modules could be interchanged
between all of the M8XXX and M9XXX series sets.
The M8500 and
M8500LC are the top of the line sets which is identical to the M8110,
but with the addition of the astigmatism (stigmator) circuits that gave
additional beam focusing capabilities, especially in the corners of the
image. While an M8110 can be turned into an M8500 by adding the missing
astig components, they are very hard to find on the surplus
market. The M8500LC is a liquid coupled version of the M8500.
The M9000 was
released in 1992 and used 9” liquid coupled tubes. These sets provided
better resolution than the M8000. In 1995 the M9000 was replaced by the
M9500LC. The M9500LC is the flagship model in the Marquee line,
retailing for over £25K when new These sets are used as the
industry standard for very high end flight simulators. Modular
construction is used throughout the set for simple filed service for
most failures. The older M9000 model is very similar in performance to
the later M9500LC, and should not be ruled out as a high end projector.
The exception is the very early production run of the M9000 that used
Thomson tubes instead of the more popular MEC tubes. That early model
had issues, and should be avoided.
In 1998, an
'Ultra' designation appeared, which added additional features and
refined geometry controls. The M8110+, M8500 Ultra, M8500LC Ultra,
M9500LC Ultra and a few other special simulator models are built today
by VDC in Florida, as they acquired the Marquee program from Christie
Digital around November 2001.
