After having talked to a lawyer, I have been told that I can make my new
BIOS for the Rainbow available to others.  I have written letters to DEC
about this, and have been ignored (as expected).  So I am planning on
making the BIOS available in the near future, as soon as I get a few bugs
fixed.

What this will entail is the following:  You send me proof that you have
purchased the original DEC code (such as the original DEC disks), and I
will modify it for you to work with double-sided disks.  I will send back
another disk containing the new BIOS and bootstrap programs, as well as a
double-sided floppy disk formatting program.

I also plan on providing, if requested, two double-sided disk drives
along with cabling and power connectors.  Unfortunately, the company from
which I purchased my disk drives appears to be out of business, so I am
looking for a new source for the disk drives.

I am writing an article to be sent to Rainbow News, the newspaper of the
International Rainbow Users Group, that describes what I did and what I
will be offering.  Look for it there soon (I hope).


I have asked this before, but received no responses.  However, I will
try again.  I would like to add code to read IBM PC/AT disks, as well as
3.5 inch disks, but I do not know the formatting of them.  Does anyone
have the formatting information for PC/AT disks?  Does anyone have the
electrical and formatting information for 3.5 inch disks?  Can the 3.5
inch drives be connected to the Rainbow disk controller?
