The Vectrex was the first and only home-based system to ever use a vector-based screen.
We have the Milton Bradley built version of the vectrex, from 1982. We also have another Milton Bradly system, the very first portable game system with replaceable game cartridges the MicroVision.
Technical specifications Vectrex
Circuit board
- CPU: Motorola 6809 @ 1.5 MHz
- RAM: 1 kB (two 4-bit 2114 chips)
- ROM: 8 kB (one 8-bit 2363 chip)
- Cartridge : 32 kB
- MOS 6522 Versatile Interface Adapter (VIA)
Picture
- 5" Monochrome CRT
- 8-bit ADC with current output feeds two resettable integrators controlling x and Y of beam, for drawing vectors
- Z control for dimming CRT beam
Sound
- Sound: General Instrument AY-3-8912
- 3" electrodynamic paper cone speaker
Control
One or two analog controllers, each using an x-y analog (potentiometer) joystick, and four action buttons.
Connected to main system using a DB-9 connector on a curled cable.
Power
Mains powered.
Software
The game built into the Vectrex, MineStorm, would crash at level 13. However, on some machines the game would continue until the highest level.
The system has a slot on the right side for game cartrdges. It uses cartridges with a single ROM chip in them.
Different plastic colorized overlays that came with each game can be put in front of the CRT to add some colour.
We have:
- Clean Sweep
- Spike
- Solar quest (with color overlay)
- Scramble (with color overlay)

Video
Video Display Processor: LCD Custom Driver (made by Hughes) (our screen does not have "screen rot").
Sound
Piezo beeper
Control

Power
Power requirements: One or two 9 volt batteries on earlier Microvision consoles, one 9 volt battery on later Microvision consoles Power Dissipation: 110 mW (TMS 1100), 1 W (8021)
Software
Software stored in the Microcontrollers mask ROM, uses the LCD batteries and keyboard matrix of the main system. we have the basic three games that came with the Dutch release of the system:
- Vier op een rij
- BlockBuster
- Shooting Star
Now donated to Awesomeretro
The original owner of the Vertex and Microvision donated these systems to Awesomeretro http://awesomeretro.org to they are no longer with us!
