C64DTV Transfer Cable
The cable connects a C64DTV Joystick Port (1 or 2) to a PC Parallel Port.
The software fully usable, and has been tested under w2k and GNU/Linux,
but should work fine under NT/w2k/XP and even w98.
Current transfer rates are roughly 12Kbytes/s dependant on the load on the
PC.
Remote Control
There are advantages of using this with Joystick Port 2
(automatic remote control from the PC).
When using with Joystick Port 2, you will probably want to include the
"Thru" connector so you can use an external joystick while the cable is
plugged in.
To be able to use the remote features, your Joystick Ports on the
C64DTV must have the Reset line wired to POT X on the Joystick Ports
you use for the cable. Components
I used BAT54 surface-mount Schottky-barrier diodes. BAT85 are equivalent hole-mount types. Other low Vf-types may work, but if
you are unsure, ask someone who has experience. (1N4148's will not work)
A small number of PC-/motherboard-types may have trouble communicating through
this cable.
Verified working:
- ASUS P4PE + BAT54
- MSI KT3V + 1N5822 (nojoopa)
Software
Download: dtvtrans-0.6.zip (2007-01-03)
(previous versions: dtvtrans-0.5.zip,dtvtrans-0.0.2.zip, dtvtrans-0.0.1.zip)
The transfer software requires giveio.sys to be installed, as it needs direct parallel port access.

Use this as much as you want, but please give proper credits.
Watch this space!
