i've been working at the ti99 joystick adapter box found here
http://www.mainbyte.com/ti99/hardwar.../joystick.html
for a while now.
Notes:
Pin four off the TI, not six, appears to be fire.
I did this project first with hacked up genesis extenders. It failed twice; first time i had directions but no fire. second time, i had fire but no up.
The third time, i bought a project box, a crimper, cable ends, the works at radio shack, good bye $12+ too much time.
Anyone actually DONE this project? I'm getting just a LITTLE impatient with this damn circuit...
