ok, here is ah short summary, how to connect a second joystick to a pc, just for less than dm 15,- , just for playing some games not alone. bich@hpsciz.sc.hp.com (Bich Tran) wrote: >Second I/O game port: 200h >First 201h that's partly correct, for the data of port 0x200 is equal to the data of port 0x201, looks like not-complete address-decoding. dgil@pa.reuter.com (Dave Gillett) wrote: >It's the same port: four bits for joystick 1, and four for joystick 2. ok, that's absolutely correct. You can find both joystick-ports on one connector. Every joystick uses two analogue signals and two digital ones. The simples thing is to build a Y-like cable, connecting these pins IO-Card (15pin male) Joy1 (15pin female) Joy2 (15pin female) 1 5 V - 1,8,9,15 2 D1 2 - 3 A1 3 - 4 0 V 4,5,12 - 5 0 V - 4,5,12 6 A2 6 - 7 D2 7 - 8 5 V 1,8,9,15 - 9 5 V - - 10 D3 - 2 11 A3 - 3 12 0 V - - 13 A4 - 6 14 D4 - 7 15 5 V - - D1 means digital input 1, coming from a button, A1 means analogue input 1, coming from the variable resistor. I have never seen such a cable in germany, but I think, it is easy to build for less than dm 15,- hope this posting will help someone Roger Schwentker, roger@larry.ruhr.de What do you see, when you turn out the light, i can't tell you, but I know it's mine.
