Up for sale is an authentic vintage Compaq-branded mechanical rollerball mouse, manufactured by Logitech (Model M-S48a). Featuring the classic teardrop ergonomics of the late 90s and early 2000s computing era, this mouse features dual responsive click buttons and a rubberized center scroll wheel, capped off with a standard legacy teal PS/2 connection cable.

Condition & Testing Details:

Fully Functional & Bench Tested: This mouse has been fully tested and bench-verified for performance. Testing was completed on a Mac and PC utilizing a hardware USB-to-PS/2 adapter. Both primary click buttons click cleanly, track accurately, and the center scroll wheel scrolls seamlessly.

Mechanical Components: The bottom twist-locking tracker assembly ring has been opened and inspected. The internal structural cavity is clean, the secondary rotational tracking rollers spin freely, and the original weighted gray rubber tracking ball is included and tracks perfectly.

Cosmetic Condition: The mouse is in good pre-owned vintage condition. The classic off-white plastic casing shows light, uniform signs of historical handling, micro-scuffs, and gentle age wear. The bottom gliders show typical surface smoothing. The factory manufacturer data stickers and matching assembly/spare barcodes on the underbelly are 100% intact and highly legible. Please examine the macro photos to evaluate the exact cosmetic state of the shell.

Please Note: This listing is for the native PS/2 mouse unit only.
