Old DOS
There is no new X-Press software for the Amiga. I've got it running on a 2.0
equipped CDTV; aside from making sure I wasn't using overscan, I don't
remember having to do anything special to get it to run.
It sounds like something is corrupting ram; you might try using the
development tool 'Enforcer' and see if you can track down what's going on.
