From the project

Vectron VGA Plus Text Mode simplifies displaying text with retro computers and microcontrollers by hiding the pixel-level details.

Vectron VGA Plus Text Mode simplifies displaying text with retro computers and microcontrollers by hiding the pixel-level details. Supply only row and column positions, and an ASCII character code, to write text to a 40x30 character VGA display.

Vectron VGA Plus Text Mode accepts row, column, and character codes into 8-bit flip flop registers from external systems. Using a 6502 processor and pre-programmed ROM chip (code here), these values are translated into a series of pixels to be drawn at x,y coordinates on the screen. Both the program, and the library of available ASCII characters are…
