Re: Revive Milan support

Hi Izumi, Jun, List,

thats awesome news. Even though the userbase of NetBSD on Atari is probably
low, i want thank the donator of the Milan board, too.

I can only guess how unrewarding support for such a little system is,
so here is my little feedback: Thanks for staying Atari, thats great
work, keep up the Atari-port!

Stefan
