Hi all,

First batches of the MOOH board will soon be shipped out to those who
pre-ordered. The MOOH is a cartridge board that incorporates 512 KB of
memory and an MMU similar to the one in the CoCo 3, in addition to an
SPI interface, SD card slot and a ROM socket. The main idea is to
allow Dragon and CoCo 1/2 to run NitrOS-9 Level 2. The board is also a
good platform for FUZIX. With an SD card and boot ROM, it is a
complete system for running these operating systems (no MPI needed,
although supported). The board requires no modification or opening of
the computer. It fits an FD-502 or CoCoSDC enclosure.

The board has briefly been mentioned on the list, and there is a post
with more information at the Dragon forums:

The boards have been tested pretty well, and the software support have
come a long way*. Orders keep trickling in, so I am thinking of making
a larger batch of them. Now is therefore a good time to express your
interest in the board. Except for the few first lucky ones there will
be some delivery time, whether I keep soldering myself or use an
assembly service.

Technical and general questions about the board is fine here on the
list. For orders please visit http://tormod.me and find contact
information there - please don't repost here.

*) FUZIX runs well using a non-optimized tweak of the dragon-nx32
platform code. NitrOS-9 Level 2 boots and runs many commands, using
DriveWire (other disk solutions should work in an MPI), there is a
boot module for the built-in SD card but no driver module yet (rbsuper
should be the way to go). Well supported in XRoar.

Best regards,
