I understand that there is a port under development Down Under in either Australia and/or New Zealand. Is there any word from Microware about working something out with Commodore? Such a combination would definitely make one magnificent machine! ------- Keith "Been OS9-ing for years!" Ellsworth Editor Public Broadcasting Service

There was a board for the Apple ][ by Stellation called the Mill. It had a 6809 CPU and OS9 Level I. I tried it, but it is lacking. A 65816 could probably handle it, but it would be messy. Your best bet would be to get that MM/1 or TC9. The TC9 looks nice for a 6809 OS9 system and the MM/1 looks like an absolute dream for OSK. Look into the video processor on the thing. -- %% Dru Nelson %% Miami, FL %% Internet: dnelson@mthvax.cs.miami.edu %%
