I have an 84C, an 83+, and a bricked 84+SE. I also have the USB cord, and a 2.5mm to 2.5mm jack connector.
Is there any way I can get programs onto the 83+? BASIC programs will send to my 84C, and to the 83+… but I can't get, for example, MirageOS. The 84C won't accept it.
Regarding the bricked 84+SE (which would solve it if fixed), it just doesn't turn on, and will sometimes display random pixels when I battery-reset it. That's after sending it TIOS 2.55 and 2.43… but KnightOS works, somehow. Unfortunately, KnightOS is currently not useful.
Any solutions to the linking dilemma or the bricked 84+SE? Any additional information needed?
