The Newton MessagePad 2000-series devices had a little known internal slot intended for an integrated modem card that was never made by Apple. PCMCIA WiFi cards of this era do not support modern WPA2 encryption. This site outlines a project to build a WiFi board for this never-used internal serial slot that works with modern WiFi networks.

Instead, I've designed a replacement cover that does not interfere. For good measure, I added an embossed WiFi logo to indicate that the internal WiFi card is present.
The STL files for the port cover can be found here: https://github.com/jake-b/Newton-Internal-WiFi/tree/master/Port%20Cover
