Installed all of the drivers required for adding a PCMCIA Ethernet card to my Newton 2100. Followed these instructions. Transferred the files from my work PC to the PowerBook using a floppy disk (how retro). Haven’t tried connecting to anything yet but it should be OK. One thing of note is that while inserting a modem card causes the Newton to alert you that a communications card is installed, inserting the Ethernet card does not. Does anyone else have any experience with this?

[Edit: According to this site, this behavior is normal as I have 3Com Ethernet card].

Also took some time to set the PowerBook 190cs up a bit better – cleared out incompatible Control Panels and Extensions.
