The PB 190 has infrared, which only supports Apple???s IRtalk in Mac OS.
But it doesn't matter for Linux since IRDA support has been removed.

Supporting LocalTalk in Linux would be great for communicating with
older Macs (and even better if you're talking about TCP/IP over
LocalTalk, which would potentially allow Internet access via some
LocalTalk/Ethernet bridges).
On the 190, I can use a PCMCIA network card in Mac OS, which along with
the FTP server in NCSA Telnet 2.7b4 can be used to move files reliably
to and from any HFS volume. It sounds like there may not be enough PB
190 users to justify spending any more effort in getting PCMCIA working
in Linux.
