Editing Osborne 1 General Maintenance (section)

== Device-Specific Subsystems ==

=== CRT Display ===
* The 5″ monochrome CRT is robust but sensitive to voltage surges and capacitor failure.
* If the display flickers, collapses, or shows distorted text, check CRT board capacitors and flyback transformer.
* Discharge the CRT before servicing—high voltages persist after power-off.

=== Floppy Drives ===
* Osborne 1 uses single-sided Shugart-compatible 5.25″ drives.
* Clean heads regularly; avoid using degraded or “shedding” disks.
* If drives fail to spin up or eject, inspect belt and lubricate moving parts with plastic-safe grease.

=== Cooling and Ventilation ===
* The Osborne 1 relies on passive airflow; ensure vents are clear of dust and obstructions.
* Consider adding self-adhesive heatsinks to voltage regulators if operating in warm environments.
