It has a Comm Slot 1 and an LC PDS slot, both right on the slide out motherboard. The Comm Slot looks a bit like a PCI slot, and the LC slot looks more like that NuBus slot (long retange with rows of pin holes). There is also a video in/out slot, that will look like a tiny card edge connector slot. Nope, couldn't have used that on the 630 anyway. for the day. If you are doing file/print sharing, I would use AppleTalk if possible. The key is can any of the servers you are running speak appletalk. (NT4, Win2k, Netware...). AppleTalk isn't the most secure protocol as far as packet sniffing is concerned... but very few internet routers will route it, so it is a fairly safe bet that the traffic will not go beyond your lan (as your internet router box will most likely ignore the packets and not pass them along). Appletalk has the added advantage of just working. It finds its own node address, and sniffs out the network by itself. Pretty much turn it on, and it works. It doesn't get much easier than AppleTalk. Downside is, it tends to be a bit chatty, and it isn't real fast (usually about 4Mb/s on a 10Mb network is the best you will get. AppleTalk of TCP/IP is much faster, but then you run the same risks you do for any TCP/IP traffic) Eh... not really. There are software things you can run to route Localtalk (built in to all macs since the 512kE IIRC, definitly since the Plus) to Ethernet... but somewhere you will still need the hardware connection to go to Ethernet. But you should be able to lay your hands on an LC Ethernet card for the 630 with ease, and fairly cheap. Worst case, if you don't find one local, let me know, I can probably turn up a spare and let you have it for a song (read: probably free + shipping depending on how fast you need it, my time schedule, and how many I have kicking around) -chris <http://www.mythtech.net>
