Look what I found! Old PCMCIA and CF Cards for Laptops of early generations.
Before the introduction of USB ports, the PCMCIA (or PC Card) provided the first true way to expand the features of your PCs (and cameras). For the millennials, it will be hard to imagine a time when laptops didn’t have Wi-Fi or even Ethernet (LAN) ports, but they did. And you used these PC Cards to add new features to them and they worked well for the times but were expensive.
I can’t recollect what we were using a laptop for without any networking, I can remember for the first PC I had used in 1987, it had only floppy drives, ran MS-DOS and GW-Basic.
