I came into possession of this Atari 1040 STE (my childhood computer!) with the intention of fixing it up. I don't remember exactly what's wrong with it, but it does have some damaged keys on the left side of the keyboard that are permanently recessed. This may be the only problem, I'm not sure.
The unit powers up but I do not have a monitor to test it with. I also do not have any cables or peripherals.
S&H is $30 within the US, or you can pick it up from me for no S&H charge if you live in the Detroit area.
Feel free to let me message me with any questions you may have.
