[Coco] The ultimate VCC hard disk image using EmuDsk

[Barry Nelson]

I have noticed that the executable for the game rogue was missing from this
image. I have created a new image and will upload it this evening.

I can see that your disk is based on my programs at
http://aaronwolfe.com/robert.gault/Coco/Downloads/Downloads.htm
which include under "10) RGBDOS" utilities to build such a virtual hard
drive 
and the OS-9 driver/descriptor /V# for accessing "drives" in the Disk Basic 
partition of the .vhd. A similar stocked .vhd disk was on the VCC emulator
site 
using RGBDOS.
I'd bet that most if not all of the games are from the collections by Briza
at 
the CoCo Downunder site. While that site seems to be down, the collection is

available at

I used those and other sources to compile the collection on this disk. The
HDBACK program was written by me, the OS-9 partition also contains my source
code to XCOM9, plus misc other source code I have accumulated, as well as a
functional C compiler. NitrOS9 was upgraded from 3.2.8 to 3.3.0. Many other
programs, utilities and files were added under OS-9, many from my own hard
drive image. The AUTOEXEC program was tweaked and updated, an exit to BASIC
menu choice was added. The NitrOS9 boot was tweaked and updated. The
following loadable driver modules were created by me and tested. To use them
run (for example) load drivewire_mods

 

drivewire_mods Provides access to to drivewire becker port drives and
devices.

printer_mods  Provides access to the /p device for printing.

vdisk_mods    Provides access to /v0, to allow access to RSDOS virtual
floppies from NitrOS9, use dmode /v0 and set the stp value to specify the
virtual floppy to access. The tsp value defaults to 255, to allow you to
easily update the virtual NitrOS9 boot floppy.

ide_ff50_mods Provide access to an emulated Glenside IDE controller at
address FF50 to allow access to up to two hard disk images.

ide_ff60_mods As above, but changed to address ff60 to coexist with the
EmuDisk driver. By using this you can mount up to two more hard disk images
for a total of three without using a Drivewire server.

 

There are many other programs and updates, have fun exploring and feel free
to ask questions.

Try the "meep" command, and also "ball" and "maze". :) Some of the NitrOS9
programs will require you to change your CMDS path using the chx command to
run them, and some will require you to be on the 32 column screen when you
start them (switch screens with the "Home" key).
