Greetings all! I have a '92 with ROM version 1.3. AFAIK, this is a rather old version; what problems are known to exist? I don't mean like described in ti_bugs_etc.zip file; those are for people who are TRYING to crash it. Is it worth it to upgrade ROM? How is it possible? The FAQ said "it is possible", but said nothing about how. Thanks, Oleg.
