Mac Peripherals: PCMCIA

Card readers

iBuffalo PC card Adapter for Compact Flash Works great with a 4 GB CF card formatted in HFS (across a 540c running System 7.5, MacOS 8.1 and a PB G3 MacOS 9.2), and with an 8 GB CF card formatted in HFS+ (on a 540c running MacOS 8.1 and a PB G3 running 9.2, and then that card works fine in macOS X Catalina)
Green House Multi PC CARD Adapter Only supports standard SD (no SDHC, so max 2 GB SD cards) and only support standard Memory Stick (so max 128 MB). Works fine with a 2 GB SD card in System 7.5 (PB 540c), MacOS 8.1 and MacOS 9.2.
Maxell 5in1 Adapter Bought this to use SDHC cards (4 GB+) and MemoryStick Pro(Duo). But I can't get a 4 GB, HFS+ formatted SDHC to work between macOS Catalina and either MacOS 8.1 or MacOS 9.2. Catalina and 9.2 are happy to format the disk as HFS+, but 9.2 can't read a Catalina-formatted disk and Catalina can't read a 9.2-formatted disk. MacOS 8.1 tried to format but throws up an error.

Wi-Fi

Wi-Fi is discussed in other sections

What else is there?

I'm always keeping an eye out for some other interesting cards, but anything else I've found is either Modem (already built-in to my Macs), Ethernet (already built-in...), USB (already built-in, or not supported by the old OS), or radio cards (those 2G networks are shut down). I might pick up a harddisk though! Those are a risky buy though, high chance they're already dead.
