Re: IIGS composite video->VCR

Thats not totally true. Seven and a half years ago I made some video
tapes of the IIGS programs I had written for my resumes to get into
the game industry. (For some strange reason, nobody owned Apple IIGS
computers anymore. Don't ask me why! ;) The only way I could show them
my work was with video tapes. Of course, I had someone with expensive
video editing equipment help me but we were able to record 80 column
text after he made some adjustments. (I had written a text mode
basketball game.) We were also able to record my 3200 color demo as
well. But you are correct that the color text settings are not
applied. Black background with white text is all you get.
