WTF?

The C64 Direct-to-TV, called C64DTV for short, is a single-chip implementation of the Commodore 64 computer, contained in a joystick with 30 built-in games (C64_Direct-to-TV).

The joystick can be bought at Conrad (but I've also seen it at Zielpunkt) for ~25 Euros.

This is an amazing piece of hardware, but comes with a few weaknesses:

• Only 1 joystick, no support for two-player games
• Only a limited selection of games
• The quality of the joystick itself is far from the gold standard (Competition Pro)

..so let's remedy this:

Project Overview

The goal is to add ports for two external joysticks, a PS/2 keyboard and a disk drive (1541 compatible).

• 2x 100 nF Kondensator (we've got more of these in the lab)

Connectors

I have fitted the connectors onto the casing of the joystick, using a dremel and a glue gun (NB! no gaffa was used in this project :).
