I haven\'t used OZ for a long time, but I used to have a 5500, wasn\'t the issue with running Hancom on OZ/OPIE that an older version was required? I got Hancom working but it was such an old version it was really bad, MS-Word/Excel compatibility was either non-existent or poor, I can\'t remember the details, either way, it was unusable. I\'m not sure about TextMaker running on it, I\'m not aware of anyone in the beta group using OZ. Hancom and Java issues were the reason why I abandoned OZ. I could be wrong but I am pretty sure you will have to use a really crappy old version. There was a OPIE alternative wordprocessor which was more of a text editor with formatting and saved docs as HTML, it wasn\'t very good for general use and a spreadsheet too but I had problems with that. I ended up using tkcROM on my 5500, everything worked fine then.
Best of luck!
