== Known Issues ==

* '''PSU capacitor failure:''' The most common failure — aged electrolytics in the SMPS cause instability, failure to start, or random crashes. Preventive recapping is strongly recommended.
* '''Floppy drive failure:''' Internal drives wear over time; heads may need cleaning, and belts or the entire mechanism may need replacement.
* '''Keyboard membrane:''' Degrades over time, causing sticky or unresponsive keys.
* '''RF modulator degradation:''' Produces increasingly poor TV picture quality over time. Can be bypassed for composite output or replaced entirely.
* '''DRAM failure:''' Ageing RAM chips can cause garbled display, crashes, or boot failure.
