Re: Hacking on Integer Basic, and ProDOS

["Bryan Parkoff" <nospam@nospam.com>]

Hello,

    I agree that INTBASIC from DOS 3.3 Master is never the same as original 
Integer BASIC on ROM.  I wonder that FPBASIC may not be the same as 
Applesoft BASIC on ROM???  I had Integer BASIC ROMs on motherboard and 
Applesoft BASIC ROMs on the ROM card as Applesoft BASIC / Integer BASIC 
switch.  It is how DOS 3.3 Master detects Integer BASIC on ROM before it 
begins to load FPBASIC into 16K RAM.
    I like reading hacking Integer BASIC on ProDOS.  I think that it is bad 
idea to put Integer BASIC below 48K while ProDOS is running with Applesoft 
BASIC on ROM.  I suggest to leave Applesoft BASIC's zero page alone so you 
can write Integer BASIC from scratch to be placed on ROM.  The new version 
of Integer BASIC is never the same as original version of Integer BASIC. 
New version of Integer BASIC always use "4C" in $E000 instead of "20" in 
$E000.
    It can still use Applesoft BASIC's zero page while they are mapped to 
use for new version of Integer BASIC.  It means that you can put new version 
of Integer BASIC in $D000 through $F7FF ROM rather than $E000 through $F7FF 
so the length might be increased.
    You boot ProDOS which it does not have Applesoft BASIC on ROM.  It will 
still detect new version of Integer BASIC on ROM that shows "4C" in $E000 
instead of "20" in $E000 before it will begin to load INTBASIC.SYSTEM.
    It is what I would like to suggest my idea.  Please give us a feedback.
