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:
The goal is to add ports for two external joysticks, a PS/2 keyboard and a disk drive (1541 compatible).
Parts, Conrad part numbers and total price in Euros:
- 2x SUB D-Stiftleiste 9 polig 742066 1.14
- 1x Mini-DIN Steckdose 738422 1.73
- 1x DIN Einbaubuchse 6-polig 738166 1.20

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