You should be able to discern a reasonable list by looking around in the the installed kernel modules. Start with something like /lib/modules/your-kernel-version/kernel/drivers/net. Your old 3Com card is about as old as there is. The list of supported ISA-bus cards may not be very long. You might find it convenient to upgrade to 10-base-T, or go really crazy and go to 100Mbit speed, if you have a PCI slot.
