This looks quite interesting. Thank you for the links.
In general: if there are sources and the OS itself is suited for these "slow" maschines, it could be ported to Kiwi. But it would not run out of the box as the hardware is too different.
In the end, it all depends on the users: It might be obvious that I can't do all (hardware and all the software) by myself. Thus if you like, start a port and get help from me and the others if you have questions or if you stuck.
What I can say is, that a working basic port could be done in a few weeks if the sources are clean and have good documentation. Even if you are an average programmer. At least this is my experience with porting EmuTOS.
Anyway, I appreciate every new program. If you come around with a working port of anything (OS, game, demo, tool, ...), you would see me smiling.
