\"\"<\/a>„ASTRO WARS“ or „GALAXY II“ is the name of the table top game console that I am introducing here. It is the home version of the arcade game „Galaxian“, which was implemented as a small tabletop device for everyone at home. The manufacturer was Epoch, which sold the device in 1981. There was also a clone made by Grandstand under license from Epoch. The device was named „ASTRO WARS“<\/p>\n

As was the case with many game consoles back then, the technical structure is a „stand-alone“ console. This means that the device could be operated without any additional accessories. You only need four 1.5V cells or a 6V plug-in power supply. The display, i.e. the display, was implemented using VFD (vacuum fluorescence display), as LCDs were still expensive at that time and were only used as clock displays due to the low power consumption.<\/p>\n

\"\"<\/a>\"\"<\/a>\"\"<\/a>The screen is designed in such a way that a curved, transparent film, printed with space motifs, is placed over the VFD tube. A Fresnel Fresnel lens shows the display content optically enlarged. The display also appears in color or shows the game symbols in color. This was solved by sticking colored foil over individual areas of the VFD tube. This gives the entire design of the ad a certain 3D effect.<\/p>\n

From the original advertising text on the packaging:<\/p>\n

„Ultra-modern arcade excitement is now yours, as you defend your earth ships against a fierce invasion. You must dodge the enemy missiles and fire back at the squadrons of attaching fightes, warships and enemy command ships. If you survive, you can attempt the exiting DOCKING MANOUEVRE and earn extra points.“<\/p>\n

Die hochmoderne Arcade-Spannung liegt jetzt bei Ihnen, wenn Sie Ihre Erdschiffe gegen eine heftige Invasion verteidigen. Sie m\u00fcssen den feindlichen Raketen ausweichen und auf die Staffeln zur\u00fcckschie\u00dfen, in denen K\u00e4mpfe, Kriegsschiffe und feindliche Kommandoschiffe angebracht sind. Wenn Sie \u00fcberleben, k\u00f6nnen Sie mit dem aufregenden Docking Man\u00f6ver zus\u00e4tzliche Punkte verdienen.<\/p>\n<\/blockquote>\n

To the technical structure:
\n\"\"<\/a>As already mentioned, the structure is based on a fluorescent display, which in turn is controlled by an NEC D553C microcontroller \/ processor. This 4Bit 42PIN IC in the DIP housing is one of the chips used very often in game consoles at that time, as it not only contains the game algorithm, but is also able to control the display directly. There is also sound that is output via a piezo. The chip only needs a power supply. The clock is generated with an external resonator … a more detailed description can be found in older articles.<\/p>\n
