Adapting old Atari standard joystick(Konix Speedking) to run on U.S.B.- P.C.

[Puresox]

Any advice on how I could adapt a Konix Speedking Joystick to U.S.B. connector? I have a competition Pro joystick which has USB connector which I intend to be the donor. Is this possible to be done without to much bother ? Or is there some kind of adapter on the market which would do the job for me?

Retrobit have been making Atari DB9 to USB adapter cables for a while now

have a look at this

here's a couple of websites with modification instructions

good luck!

Please move to other retro / PC stuff. IMHO it's not CPC related, right?
