I have created a font file for use with the MD_MAX72xx and MD_Parola libraries. It implements the old DOS CP437 font and looks quite well on the MAX7219 8x8 matrix. The source code file is: parola_cp437_font.h and is shown below.
Usage:
[code]
#include <Arduino.h>
#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include parola_cp437_font.h
MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
P.begin();
P.setFont(_cp437font);
[/code]
