Vectrex is a unique gaming system, released in 1982 by General Consumer Electric (GCE). Its peculiarity lies in the fact that all the graphics in it are vector and displayed on the handset not line by line, but by vectors, like on an oscilloscope.

The history of the appearance of the console is adequately described in Wikipedia,
and there is little point in retelling it here.
The console is a monoblock with a 9 "black and white monitor.
On the side there is a slot for a cartridge.
Rear brightness control knob is displayed.
The joystick is hidden in the bottom of the case.
The buttons and the joey itself are made very securely, like on arcade machines.
The joystick circuit is traditional for the systems of that time, two analog axes on variable resistance resistors and 4 buttons.
It's time to look inside.
And its structural scheme:
Vectrex is built on a 8-bit Motorola 6809 processor, although in my copy there is a version from Hitachi - HD68A09P. Sound is output using the AY-3-8912. Another large chip is the MOS 6522. It is a port expander with two parallel interfaces, a timer and a shift register. RAM in the console is only 1 KB. The ROM of the board stores one Minestorm game and several test utilities.
Without the top cover, the console looks like this. Monitor - Samsung 240RB4:
The date of development, 1982 is visible on the power board:28 games
were officially released for Vectrex. Each game was delivered on a cartridge. Inside the cartridge, a regular 32 or 64 KB ROM is installed, third-party developers also offer clean cards and flash cartridges.
But besides the actual cartridge in the complex with the game, there was also a so-called overlay - this is a piece of colored plastic that was inserted into special slots in front of the monitor and made the game visually much more attractive than on a black and white monitor. The demonstration is shown in the video at the end of the article.
This is not an innovative approach; for the first time overlays appeared 10 years before the release of Vectrex in the Magnavox Odyssey
Ja ja, die deutsche werbe :)
For Vectrex, some additional peripherals were produced - this is a light pen and 3D glasses!
If everything is more or less clear with a light pen, the idea of 3D glasses was ingeniously simple. In the glasses was a motor and a simple synchronization scheme. A color disk was worn on the motor, which simply rotated in time with the frame change on the monitor and closed one eye or the other.
Unfortunately, such sets were released a little, so, despite the simplicity of the device, it costs absolutely inhumane money:
