Barco 1000, 1001, 1500 and 1600. These are a series of 9" analog convergence projectors that Barco came out with from about 1989 to 1993. All very similar to the Barco 600 chassis, but used 9" Sony ES focus tubes, called the SD-146A. A great
picture when properly set up, but Barco drove these tubes quite hard, and sudden tube failures were common. These tubes are hard to find on the used market, and are insanely expensive if purchased new. 64 Khz scan rate, 1000 to 1500 lumens.

In around 1990, Barco came out with the 500 and 800 models. The 500 is a 7" version of the 8" Barco 800. The 500 put out 600 lumens, the 800 put out 825 lumens. The projectors have digital convergence which is very easy to set up, and lots of on screen menus to guide you through the setup procedure. ES

In about 1993 Barco came out with the Barco 801. The 801 was very similar to the 800, but had an extra circuit called AKB that compensates for picture tube wear. Basically the same overall picture as the Barco 800. ES focus on this set as well.

There are two versions of Barco 500 and 800 as well as other Barco models. There are Graphics and Data models of most projectors. The Data models use hybrid lenses and do not scan as high as the Graphics versions, which also have all glass lenses. The Graphics are somewhat more desirable, but in most cases the scan rate of the Data projectors is more than adequate for home theatre use.

The Data 500, 800 and 801 scan to 58 Khz, (line tripling), the Graphics scan to 92 Khz. In 1992 to 1994 Barco had a model called the Barco 700 and 701. This was designed more for the home market as the case was small and very streamlined looking. 7" Sony ES focus tubes, about 600-700 lumens, and scan rates varying from 36 Khz to 60 Khz depending on the model. This unit had digital convergence, and a very nice picture if the tubes are in good
shape. This model was not as modular as other Barco modules, requiring the projector to be sent in as a whole when servicing was required.

A higher end version of the 701 is the 701s followed by the 708. The 701s and 708 used 1000 lumen ES focus Toshiba tubes, and both sets came with component inputs along with RGB, video
and S-video.

In late 1993 Barco introduced a new series of video projectors, the 808, 1208, 1200, 1209, and 1101. The 808 and 1208 were 8" tubes with the improved EM focus, the 1101, 1200 and 1209 u
