just bought a Real Flight R/C Sim from a friend. ( just the CD -G2 Generation Sim and the Real Flight add on Vol 1) and the cables but without the controller. How do I connect my Transmitter ( FUTABA 6 Ch.) to the computer, the 90 degree offset 6 pin male connector on the cables do not fit any of my ports on my PC, DELL 4550- 1 year old. Thanks for any help.
