Regular 3Com Etherlink pcmcia cards work with the driver on Aminet (model 3C589D). Wireless cards using the prism2 chipset work (e.g. Linksys WPC11) on the pcmcia slot with the beta driver written by an amiga.org member (do a topic search). If you can find >=4MB 16-bit pcmcia SDRAM memory cards, they work with the PrepCard utility. PCMCIA SanDisk PC flash cards work with the Aminet driver for mass storage. The thin ide cdroms can be made to work with a 3rd party ide adaptor and a case mod. Of course, just about any 2.5" ide harddisk should work (with possible pin 1 modification). Memory is probably not useable, though SODIMMs work on the newer uA1 boards.
