Re: Ultima & Mockingboards on each of the Apples

["Great Hierophant" <great_hierophant@hotmail.com>]

I have done it!  I have gotten Ultima III to work in AppleWin 1.12.6.0
in the Apple II+ mode.  What I did was to replace the $D000-$FFFF
portion of the APPLE2.ROM with one gleaned from the FPBASIC on a DOS
3.3 disk.

Is that the only difference between the two ROMs, the last 2KB?  That
binary is a CRC match to my last 2KB of my APPLE2.ROM.

Also, I noticed that some DOS 3.3 images (1980) have FPBASIC and
INTBASIC at 50 sectors, their proper size, and others (1983) have them
at 42 sectors, which eliminates the last 2KB of each file.

Now, suppose that you have an Apple II+ with the older ROM.  What do
you do if you want to run Ultima III with a Mockingboard short of
burning new EPROMS with the updated code?
