--MacDeath 15:03, 20 February 2010 (UTC)Konix Speedking, I used to have this one, my favourite joy yet wasn't well suitable when the game needed an extra button/*command (such as R-Type with the Shield command...)
So :
--one button speedking : was mostly compatible with any mundane 1 button Atari controllers, so commercialised for Home computers : Atari ST, Amiga, C64, Speccy and Amstrad CPC/Plus.
--two buttons speed king : existed for nintendo (may have had extra buttons start and select) yet a SEGA model may have existed too (Sega Master system).
--Analog : was mostly for PC. It seemed to have actually 3 buttons from what I remember on advertisements, but the 3rd button may be a thing to calibrate instead..
Concerning this model pictured :
Yes it seems to be a 2 button compatible with Amstrad PLUS/GX4000/CPC. This must have been quite rare, as most CPC used the 1 button model. This is just the same as Sega compatible ones, yet slightly re-wired.
But it is in no way an ANALOG model.
Analog speed king had a different stick.

there you can also see a 1 button model with Autofire (Amiga or Atari ST...or even others)

the sega model, with 2 buttons and autofire.
There the same but in Atari/Amstrad wiring.

this one is the Analogic one.
Also 3-4 buttons may have existed (Sega Megadrive).
