Editing Atari 260ST (section)

== Known Issues ==

Due to its extreme rarity and short production run, common issues are largely the same as for the early [[Atari 520ST]]:

* '''Insufficient RAM for TOS-from-disk:''' On units without ROM TOS, loading TOS from floppy consumed ~192 KB of the 256 KB RAM, leaving very little for applications. The practical solution was to upgrade to 512 KB or install ROM TOS.
* '''Keyboard membrane degradation:''' The keyboard uses a membrane assembly that degrades over time, causing unresponsive or stuck keys.
* '''Clock battery leakage:''' Some units had a soldered clock battery that can leak and cause PCB corrosion.
* '''PSU failure:''' The external power supply can develop failed capacitors over time.
