Hello.
I tried to dig out my Turbo-R (A1ST) from the Basement, I left it there 3-5 years ago, i guess with a keyboard problem. I got "new" spares keyboard film, and it looks good so I am not sure it the keyboard film problem.
Dead keys are: Q R O P L K N M
And spacekey (and Joystick port #1 Fire1) goes on and off. So it may be a ic problem. I didn check, but I am almost sure all components in the turbo-R is smd so it might be hard to find the problem and to change the IC i guess
Anyone have experience with this problem?
if its the keyboard film i could try to make a wire from the keyboard connector to check if i can get the letters missing above. If not it have to be more complicated. I remember there was a brazil guy or something could make new keyboard films, with better quality than the ones used in the turbo-r.
