A set of Coco 1/2/3 web pages by L. Curtis Boyle
NitrOS9.LCURTISBOYLE.COM is the base address for a new set of web pages devoted to the Coco.
Thanks to Scott Griepentrog (owner of STG.NET) for supplying the webspace (for free!) from 2001-2006,
but since he is shutting the whole STG.NET domain later this year, it was time to move. It is now costing
me some money, but I should have some increased bandwidth now (let me know if you notice a difference).
is a steadily growing list of commercial games that were available for all three
models of the Color Computers, complete with screenshots, a little background,
and occasionally Easter eggs and/or hints or tips. If you know of any additional
information on any of the games mentioned here, please email me
the information so that I can update the page in question. If you are the author of
any of the programs here, and wish to give permission for making the program(s) available
for download for other users to see, please email me as well. Some of the programs
in the list have been released in such a fashion, and on those pages, you will be
able to download the game itself. Many thanks to all of the authors who have done so!
This page will contain the last version
of NitrOS9 that I actively worked on. Boisy Pitre and others have continued, and vastly changed, a lot of it since at
the NitrOS9 Project, and if you want the most up to date version (which now includes
Level 1, 2 and 3 NitrOS9's, and even 6809 versions), that is where you should go. The version I have here is 40 track DSK
image that can be used on the Coco emulators, or a real 6309 based Coco (after you follow the instructions to put it onto a
Ken is the author of many early Coco 1/2 games,
and this interview contains inside information on how the games were designed and what inspired them. Ken has been kind
enough to release his entire collection for download (see the games page above), so please send him an e-mail thanking
him (his email address is in the interview).

Download the two .DSK images that made up the official
Radio Shack Color Computer 3 demo program! This rare program was written by Spectral Associates
in 1986 to help Radio Shack stores demo the new Coco 3. There was a key sequence to hit
on the title screen that let the store manager change the monitor type or price of the Coco 3
itself, but I don't remember what the sequence is. If you have the MESS emulator, it works in it, as
I have tried it. I don't know if it works in Jeff's emulator. If you have a real Coco 3, and
you have either OS9 or NitrOS9, and a large enough drive to hold a .DSK image while leaving your
floppy drive free (either by another floppy drive, a RAM drive, or a hard drive), you can transfer it
to disk via my OS9 DSK Converter program... just fire up BASIC09, and load it. You will also need
to have DMODE (rename to just 'dmode') in your CMDS directory... make sure you set the execution attributes!
This is taken verbatim from the intro
to one of their software catalogs from the mid-1980's. Ark Royal Games was the premier war gaming
software company for the Coco.
Includes me as a teenager in my early Coco 1 days, our Coco "super-system" from Mercury Graphics, and a set of shots from the 1989 Chicago Rainbowfest.
