I will look for the bootfile :) I just grabbed a 200MC and i have a bit of 68K
ASM programming under me belt :) I was thinking of making a tiny terminal
server os that woudl let you telnet ETC from the terminal ports but i guess i
could make it go bi-directional or make just 2 slightly different kernels for
it :) Well i will let y'all know if i find anything more out about it... just
hate to break that no decompiling clause :(
