[comp.sys.apple] Videx Videoterm Card and Assembly Language

marwood@DMC-CRC.ARPA.UUCP (09/05/87)

Can anyone tell me how the Videx Videoterm Card can be used with assembly
language.  This is to be used without DOS resident in the Apple.  I need
to know how to initialize the card, where to put the character to be output
and what to call to actually send the character to the console.  I am 
assuming that it is something like:
                      STA     0CFFFH      ; Turn off all peripheral ROM
                      STA     0C300H      ; Select slot 3
                      JSR     0C800H      ; Initialize 80-col card
                      LDA     CHAR
                      JSR     0C???H      ; Send CHAR to console
I think that there may be a little more to it than this.  Can anyone help.  I
don't receive info-apple at the moment so please reply direct.
                                 thank you in advance
