Yes, your transmitter can be used with a computer. Next questions...

Which flight sim?
What operating system is on your computer?

My computer is set up with FMS, and I have hook-ups for that, but I don't know if they work on other simulators. Also, for the more sophisticated hook-ups, it sometimes takes a little fiddling around to get everything set right and working, so some skill with the computer may be handy.

I have very inexpensive hook-ups that connect to the printer port, but they will only work with Windows 95 and 98. The newer Windows systems (2000, me, xp) will refuse to allow the printer port hook-up to work and for those there is a less inexpensive gadget that includes a microprocessor and connects to a comm port.
