DIJIT Systems ADVANCED
|
The Dijit Systems Advanced Video Processor Card (AVPC) was an 80 Column card that fit into the PEB. Along with a
suitable RGB monitor turned the TI-99/4A console into a 80 Column device. In Dijit's own words:
Installs in the Peripheral Expansion Box 99% Compatible with Existing TI-99/4A Programs 80 Column Word Processing 192K of Video RAM Crisp Vivid RGB Video 512 Color Palette High Resolution Bit-Mapped Graphics Up to 8 Sprites Per Line Mouse and Light Pen Port Supports Video Overlay Supports Video Digitizing |
The AVPC did require some hardware changes to the console to work correctly, and included a jumper which included
a couple of 1.1K resistors. There was also 1 trace that needed to be cut.
