The Masochist's video card is a pure TTL discrete logic design that generates the necessary video signals for VGA. The project name came about after the hours I spent wire-wrapping the project together yielded painfully raw fingertips. So be fore-warned if you duplicate this project, don't abuse the wire-wrap tool!

Purpose & Overview of this project
The purpose of this project is to build a system that does three things:
-  Generate Horizontal VGA Sync Pulses
-  Generate Vertical VGA Sync Pulses
-  Generate Red/Green/Blue VGA Color Pulses
The counters that we will use to generate Hsync and Vsync pulses will be 74-193 4-bit binary counters. An 8-input NAND Gate, 74-30 and some hex-inverters, 74-04, will be used to capture unique count values. Each value will have a unique function like, triggering hsync to begin or end, or clearing the count values.
