PowerBook 2400c (240). This item has been stored at home and is in remarkably good condition for its age. I confirmed its startup; it displayed immediately after powering on, and basic operations worked without issue. Exterior Condition: * No cracks or chips on the top or bottom. * Almost no scratches. * The rubber parts of the main unit and the external FDD have deteriorated over time and feel sticky. (This is a common issue with this model). Operation: * Powers on and boots to the desktop without issue. * Menu operations are smooth. * Battery life was only confirmed while connected to AC power; its functionality is unknown. (Battery life is not guaranteed). Accessories: * 2400c-specific CD-ROM (OS installation related) * Complete set of manuals (some staining) * AC adapter * Various cables * External floppy disk drive (working) * Emergency floppy disks * Two communication cards from the time: * Panasonic PHS communication card TO-PHS32K (with all accessories) * USRobotics Megahertz 56k modem card * *Although these are likely unusable now, they are included for historical reference.* Regarding the External FDD: * I have another one in reserve, but the hinge on the front cover is broken. * This is considered junk and can be included free of charge if desired. (Please comment if you would like it). Additional Notes: * No original box. * Shows typical signs of aging, but is in good condition with little use. * Due to the specialized nature of this equipment, I cannot guarantee all detailed functions or the complete functionality of all ports. This is a used item, so individual perceptions of condition may vary. Please purchase only if you understand and accept this. Returns, claims, and price negotiations are not accepted.
