Lot 3 Vintage ISA Computer Cards Hayes Modem LPX Riser Board Retro PC

PLEASE SEE ALL PHOTOS

OFFICIAL DESCRIPTION is below… but first, here’s my attempt to emotionally blackmail you on behalf of my cats.

With every purchase you’ll also be directly supporting my journey to becoming the world’s greatest cat dad. That’s right. Your purchase helps me spoil a demanding feline overlord who believes wet food should be served on a silver platter and thinks 3AM zoomies are a valid form of cardio. Every sale gets me one step closer to being voted "Employee of the Month" by my cats.

(Spoiler: still hasn’t happened.) 😭

WHAT YOU SEE IN THE PHOTO IS WHAT YOU WILL RECEIVE.

NOT THE CATS THOUGH.
