[Coco] [Color Computer] CoCo EPROM modified for the Dragon?

[drag0n1969]

Does anyone out there have a copy of the CoCo EPROM modified for the
Dragon?

  I've came aware of its existence after reading about it in Marty
Goodman's Rainbow column, archived in the Files section of this group:

"For a while some companies (such as Super Choc in Canada) sold CoCo
ROMs modified for the Dragon, and the Los Angeles Users Group had a
number of members running Dragons with modified CoCo EPROMs in them.
These modifications resulted in a Dragon that thought it was a CoCo,
would print out through the parallel port, but could access the serial
port via a PRINT #-3. Because the Dragon was now pretty nearly a CoCo
from both hardware and software points of view, it could even work fine
with a normal CoCo disk controller plugged in."
