I have this board hooked up to my Amiga 2000. Works very well. I haven't made an adapter cable for the Coco, yet, but I am sure it will work.

I saw this "out of the box" module

Could it be used with CoCo?
It seems cheaper than the VGA board plus the Altera DE0-Nano board.

Hi,
As I want to finish the Rainbow on Tape / Disk project as soon as possible
(Way over due), when you get the time will you please check if you have any
of the missing Rainbow on Tape / Disks. The early years (1982-1984) and the
late years (1990-1993) are missing many months.
No hurry about getting them to .dsk format, if there are none then I will
finish up the project. Perhaps someone will loan you a Drivewire enabled
ROM cart or a COCOSDC and MPI :) .
http://home.mindspring.com/~sfischer13/
That number of disks needs to be converted with help from others, some of
the Rainbow Disks may require special methods as both sides are often used
and some have both DECB and OS-9 parts on the same side. Other disks may
have this mixture also. Many will have been done and are online already.
TIA

Which begs the question do you have a computer that can run Drivewire to
connect from your CoCo?
Checking what type of OS you are using I found "Outlook" which suggests
Windows which will run Java as well as many other OS's.
Please correct me quickly if I am wrong and you will be given a Good
Computing Seal of Approval from many people here.
Allen Huffman's suggestion for you to use COCOSDC and a MPI also require
that you have a computer that can read SDC cards. My last two laptops, Vista
and W7 do and I also have a USB hub that does also.
2500 is very large number of disks, I would suggest that you build three
piles, Rainbow, Commercial Software and personal. Is there any sign of an
master index for the last which is missing from a collection of 175 disks
named 0000.dsk - 0174.dsk which has proved to contain only 1-2 Rainbow on
Disk.
The first step would be to number the disks with labels. The number of
tracks and sides should be added as soon as known. DECB or OS-9 format or
mixed.
I used a color code to separate out DECB / OS-9 and the number of tracks and
sides.
A spreadsheet, database or just a text file to keep track is also needed.
Commercial Software has a very large number of disks already converted,
those and any damaged disks I suggest you put to the end. I know where most
are stored.
Because of the speed of Drivewire to a Windows computer, that would be my
suggestion.
You can load the CoCo part from a disk and select a NitrOS-9 boot disk with
it also.

This is precisely what my "bootlink" on my web site, does Chris.
Basically the boot module you choose gets the address of the os9boot file
from its hard drives LSN0.
So it doesn't have to even live on the same hdbdos disk as the boottrack
since that address in LSN0 can be anyplace on the drive, including plumb
out of the os9 formatted portion of the drive. HDBDOS makes it piece of
cake easy to have with its offset + vdisk allocation scheme.
The syntax is "bootlink $82" or "bootlink 130" which is the decimal
version of $82. Bootlink translates according to whether or not the first
of the 3 chars is a dollar sign. It goes and gets the effective LSN0 of
that hdbdos vdisk, seeks to the file and verifies that it is indeed a
legit os9boot file, and if it is, does the math to dd.bt and dd.siz in the
real lsn0, writes it into those 5 bytes, so the next time it boots or
reboots, it will boot using the newly created os9boot file.
I have not done it yet, but what you want to do can (maybe) also be done
with the B&B utils "ba" and "bd" to clear those track 34 bits in that
disks FAT. Hardly worth it since that only gains you 6144 bytes per
vdisk. bd=Bit Deallocate. However, I do not know if these utils are
multiple sector cluster aware. From what someone else said just this past
week, the hint seems to indicate they are not.
Anyway, take a gander at it as I believe it can do this job. Get it from
my web page at the Genes-os9-stf link.

I built the 512k SIMM board, and it did not work for me. Also the layout
was not the best,
As it blocked the keyboard cable.
You'll want to go over those schematics VERY carefully. He was serious when
he said
untested.
I think someone (RETRO INNOVATIONS?) Is currently working on a mutipack.

Well, I am happy to help, but I am just in the early stages of working
on the design. For success sake, I was working on a 4 port unit first,
and then seeing if the idea held merit to do more slots.
I am replying to you, but I think there is some value in having the
discussions in the public arena. The forums can be a goldmine of
information for later folks.
I am still gathering information, such as:
* As noted in an earlier question from me, the difference between the
units. Darren provided a nice piece of information
* If addresses did not overlap, would there be utility in having
multiple slots "on" at once for SCS or CTS (or both).
o Because, I can see someone wanting a FDC, an HDC, a modem,
Ethernet, and maybe a Speech cart on all at the same time.
o Your "stack on" idea would be easier to implement with this in
mind. Put all the carts in the address space at one time.
* If so, how would it be best to enable this new feature without
messing up the older apps.

How did you resolve the non-standard disk issue? I have many 40 track
