Subject: Teletext Display Error

Hmm....

I haven't got a TV that's actually tuned into the analogue broadcasts
to check, but it's possible that that are using Black Text ..
Logically this would be CHR$(128) bt the SAA5050, like most chipsets
of it's era, doesn't support it,

If you save a page, then *DUMP it, see if the text is there, preceeded
with an &80.
