Re: Alternate character set + Ext 80 col/AppleColor RGB card

Thank you for verifying what was only a vague memory for me... the 16 color
Text mode.

As for your question, the Mouse Text is an extra character set in the
character ROM on the motherboard, enabled by a softswitch.

$C00E to enable MouseText
$C00F to disable MouseText

I might have that backwards though.

Enjoy
