(Much like there used to be parallel port ethernet adapters for PC's.) Both the Lisa SCSI card and the ethernet<->SCSI adapter are quite rare these days, so it's not much of a solution. However, the Lisa does have a pair of built in RS-232 ports, one of which can be used for appletalk (localtalk) so it can go as high as 230kbps. Of course, it's very difficult getting the Lisa to sustain much of any serial conversation above 19.2, even with hardware handshaking, and leaving it enough CPU cycles to do much of anything else. But then again, if you can build a TCP/IP stack for Lunix and Con-Tiki on C64's, it can be done on a Lisa too... As as aside, there were lots of very strange things on SCSI busses back in the day. Scanners were quite common, but there actually existed printers, and even video cards on SCSI busses. :-) The SCSI video card and ethernet card were useful for compact Macs that had a scsi port, but no expansion slots. The Lisa does have 3 expansion port slots, so it if you're going to build hardware, you could easily build an ethernet controller for it, but they would be quite expensive, and not very useful in terms of how much bandwidth you'd get out of them. But serial ports are free as they're built in, so only the software half is needed. Very true.
