This is an Orinoco Classic Gold PC Card. I used it about 15 years ago with a PowerBook 5300. That model had a cheap feel, with the LCD screen attached with double-sided tape. Furthermore, since this 5300 didn't support AirMac cards, this was one of the only wireless LAN cards available at the time. I think the OS was 8.x. I'm selling it because my MacBook was completely destroyed by vinegar a few years ago. Currently, its operation has not been confirmed. Due to its communication speed and only supporting WEP, it's likely useless in the present day, but perhaps you could display it as a commemorative item. Please purchase only if you understand the above. Instant purchase is welcome. Thank you for looking.
