Could anyone point me in the right direction on how to read joy stick values on a PC in C or assembly? Thanks, -- Chuck Noren (303) 971-7930

INT 15H, AH=84H - Joystick Support Input AH =84H DX =0000H Read Switches =0001H Read Potentiometer Returns AX =Switch settings, if DX=0000H POT A(x), if DX=0001H BX =POT A(y), if DX=0001H CX =POT B(x), if DX=0001H DX =POT B(y), if DX=0001H CF =0 IF =1 The Joystick that I bought claims that the 'pot' values read will vary with the speed of the machine. You should assign a value for 0,0 to the pot reading at entry, or at a specific 'recalibration' time. -- Clarence A Dold - cdold@starfish.Convergent.COM (408) 435-5274 ...pyramid!ctnews!mitisft!professo!dold P.O.Box 6685, San Jose, CA 95150-6685

See the latest "Circuit Cellar Ink", it has an article on
"Using the IBM PC Joystick".
If You can't get one, let me know, I might type in the pascal/asm/c code
to e-mail it.
BTW: does anybody know the literal translation of "Joystick" into German?
(I mean LITERAL, not "der Joystick")

A DOS call??? Why is it that I found it in my Compaq 386 Hardware Tech Ref? I believe that it is a BIOS ROM call, since it appears in chapter 4, "SOFTWARE ASPECTS AND BIOS" Besides, you aren't the one that asked for it. I already got e-mail from Charles Noren telling me that it, and the c-source that I mailed to him, worked. Of course he might be running DOS. And just a parting shot....... Why don't you change your .signature so it fits on a line? -- Clarence A Dold - cdold@starfish.Convergent.COM (408) 435-5274 ...pyramid!ctnews!mitisft!professo!dold P.O.Box 6685, San Jose, CA 95150-6685
