- I'm working with the Atari System VR4 on the TT. I encountered a problem
- similar to yours when I tried to boot up UNIX the first time. Atari said
- there was a problem with some older TT models and a wrongly programmed GAL
- that has something to do with the coprocessor. They sent me a plan how to
- fix it (easily) and it worked, indeed. So if you have a TT that still has a
- daughterboard contact me and tell me the revision number of the board. If it
- is the same as in my plan I'll mail it so you can fix it yourself.
