Atari SIO plug with FTDI PCB

I made small modification to Atari SIO plug in order to fit in the FT232RL USB to serial board from ebay. The board dimensions are 26x16mm without pin header. In the Atari plug I used 3.96mm pitch contacts (for example). To wire the PCB you must first desolder the pin header and solder jumper to 5V on the bottom side of the PCB. Then connect:
SIO 3 (Data In) -> TXD (through Schottky diode Atari --|>I-- TXD)
SIO 4 (Ground) -> GND
SIO 5 (Data Out) -> RXD
SIO 7 (CMD) -> CTS
The diode can be omitted if you won't use the adapter in SIO daisy-chain.
You may want to use the transparent filament in order to see the RX/TX activity diodes on the PCB.
