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 vertex, from 1982.
Technical specifications
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)
- 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.
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)
