My Blizzard is actually a 030/50 MHz processor. Thanks for all the feedback. I think I will go with the PCMCIA solution, even if it means I must switch it out with my SquirrelSCSI card. I really on use it for my CD-ROM Drive (which I could replace with a IDE one if a got the Fast ATA adapter with a second IDE port. I believe it will perform better than the USB one. I took a look at the latest Poseidon archive (4.4) and it looks like there were some improvement on resource use when using USB Ethernet devices. The Subway USB is great. Very versatile (USB Keyboard, USB Mouse, USB Flash Drives, Digital Cameras, etc...). But perhaps not for Ethernet.
