I am not sure if this is needed at all. The Internet Connection kit uses a pretty low level driver to communicate to PCMCIA cards. It would be no problem at all to communicate via the internal serial port with an ESP32. The NewtonOS kit includes all protocols except wireless encryption, which is integral part of the ESP. So no problem there.

I have found a perfect programmable logic chip that can interface the ESP to the internal port including the required level shifting, also adding SD Card support, keyboard emulation vie WLan, and NTK and Inspector support. All we need is the ESP, the FPGA, a PCB, and the connectors, optionally an SD Card holder.

...and time to plug it all together...
