Hmm ... I have actual TOS ROMs (the chips) but the computer hit the trash years ago. Are these illegal? Since I'm a previous ST owner I should have a license to use the ROMs however I want, and since I didn't sell the ST, I didn't give up the license .. even though the computer is gone (actually the AdSpeed and an ICD Link and some other stuff I still have - almost a whole computer).
Also, with EmuTOS+MiNT/XaAES+fVDI you can have a whole OS with no Atari copyrights anyway.
