I got the Ericsson Portable from Fake Shemp finally so I am having a look at it. It seems pretty easy to add it to the list of PC clones in pc.cpp but I'd like to add more to it like support for the custom plasma screen hardware and the built in printer. So I am planning write a separate driver for that. Here are some interesting videos on the hardware:
I also have a Swedish V.Smile Baby console and an Ericsson Portable PC I could part with no prob. The latter is incredibly heavy, so sending it whole anywhere but inside Sweden is probably out of the question.
Ok, fairly easy to get the BIOS up and running, still need to tweak all the details for the Plasma, 640x400 mode, printer and the hardware supported Ergo-disk feature, an Ericsson specific floppy image in RAM card.
