The
6309 Microprocessor Enhancements Project is underway...
I have begun to explore the possibilities of
updating Jeff Vavasour's Coco3 emulator to run a 6309 microprocessor chip.
Already I have progressed a fair amount, when you consider the work
needed to undertake such a project. First I have to become
completely familiar with the source code I wish to alter. Once
I have understood the source code, I will begin to enhance
the code while staying inside the parameters of the original source
code. I will try to keep the same coding style, close as I can
to the original style of source code.
Since I began this project Jeff's coco3x emulator has gone through
significant changes. See the info text file for changes the emulator has
gone through.
The project help page can be seen here.
It shows and explains the new additions to Jeff's TRS-80
COLOUR COMPUTER 3 Emulator. If you like to
have the last Windows Help File made for the project click here.
The 6309 Monitor and Debug Facility now
supports the new 6309 Registers, Mode
Register and Disassembly of the new instructions. Plus
additionally there is an options register and a new GIME
command.
The DSKINI and RETRIEVE
programs have gone through enhancements.
USING THE DISK IMAGES...
If you wish to transfer the disk images to a 5.25" floppy disk for use
with a real CoCo, follow the steps below:
WINDOWS 9x, Me or MS-DOS...
1. Download and install the latest version of
1. DSKINI/RETRIEVE
2. Insert a blank 5.25" DS floppy in to your drive
2. (we assume B:)
3. Type the following command,
3. replacing the name of the image:
3. DSKINI /T40 /D B: <diskimagefile>
Where <diskimagefile> is the image file you want to transfer to the
floppy disk. The image file transfer should start. When it is done,
take out the disk and try booting your CoCo with it.
Repeat steps 2-3 for each additional disk.
