Sabina TCP - the TCP/IP stack for Mac 128K and 512K
Sabina is a brand-new suite of TCP/IP Internet applications by D. Finnigan, designed especially for the original Macintosh 128K, Mac 512K, and Mac XL (Lisa 2). Yes, it will work on newer Macs too. Sabina uses PPP, the Point-to-Point Protocol, over an RS-232 serial port as its Link Layer.
