Need pinouts for Atari Touch Tablet

[sisko]

I need the pinouts for the Atari Touch Tablet, and can't seem to pull anything up on google.

 

Can anyone here help me out?

A delayed response I know, but just back from holidays and only getting to this now.

 

As for the pin outs on the TT I assume you mean the 9-pin connector? Don't have them exactly but I can give you some help here. The TT pulls power from the +5V line on the joystick port and feeds back in the X and Y position using the pokey pots in. The trigger buttons are also made up of the PIA 0-3 or 4-7 lines. i.e.

 

Placing the pen in the bottom in one corner should give a 0,0 (doing this from memory and I recall that the unit worked in reverse) on the POTS readout.

 

If you are coding for this information bear in mind to allow for tolerance as the resolution of 255 in one axis is quite what this unit can do.

That helps a bit, and should take out quite a bit of the guess work.

 

Thanks!
