Nice to see a few of us share the interest. :-) The best I can offer for a
list of patches is what I listed in the post here [
http://news.lugnet.com/robotics/rcx/legos/?n=4032&t=i&v=a ], along with
Carl's follow-up post. That list was culled from links I've collected over
the years. As was noted, there are different patches out there for
different versions of BrickOS, and those two posts are an effort to merge
together appropriate patches against the latest SourceForge version of
BrickOS. From Carl's post, the link to download the latest version of this
collection of patches is
http://sourceforge.net/tracker/?func=detail&aid=2722649&group_id=58151&atid=486699 .
The patches are numbered and are intended to be applied in numerical order.
As was also noted, patches yet to be merged deal with "reliable LNP," task
prioritization, task scheduling, memory allocation, real-time sensors, etc.
To the tools versions--
* binutils: 2.16.1 - h8300 COFF support was dropped from subsequent
releases, so unless BrickOS is updated to h8300 ELF, we will have to stick
with this version
* gcc: 3.4.6 - this is the version that I use; I think Carl has had some
success with some releases in the version 4 series
Dr. Jochen Hoenicke's Bibo is also worth considering as a "next version" of
BrickOS. I have started going through that list of patches to carry over
any relevant changes to Bibo. If I can get them ported over to Bibo, I
expect I will base any of my future "legOS" development on Bibo.
For some 404 pages, http://www.archive.org/ might be your friend; no
guarantees, though.
Hope this helps,
Matthew

Agreed. There is also a set of pages from the following school year at
http://cs.brown.edu/courses/csci1480/old/2005/brickOS/quickstart.html .
Unfortunately (at least from a code merge perspective), their "version 1.2"
is based on BrickOS 0.2.5. The lnp_printf functionality has been adapted
and included in the recently-posted rollup patches, but incorporating other
modifications, such as "Reliable LNP," is more involved due to the
difference in BrickOS versions.
> A page of patches: http://carl.troein.com/
[@Carl]: Please correct me if I'm wrong, but I believe these patches are
already included in the rollup posted to SourceForge?
If the SourceForge project wiki for BrickOS could be enabled....
I've noticed another thing that is disappearing is the custom sensors and
multiplexor boards that were created for the RCX....
Thanks,
Matthew

I have found two problems with the patches. I narrowed down the problems to
specific patches from the Bibo set. However the symptoms are identical under
BrickOS so I assume they would be linked to the same patches there.
Patch 10: Under Ubuntu with the usb tower, this causes firmdl3 to exit with
error "read: resource temporarily available". However the light does light up on
the tower for a small moment.
Patch 11: This seems to do something funny with the motors. Power does not seem
to be supplied to the motors. when running the motor, the arrows appear on the
lcd however there is no power being outputted.

Patch 10: This works for me under Cygwin with a USB tower, but some of the
files such as rcx_comm.c have a bit of platform-specific code.
Patch 11: I've noticed that the linker command file is a little different in
Bibo than it was in BrickOS. If _motor_controller is 0x00 in bibo.ld and
dm_mask is set to 0x00 in dmotor.c dm_init(), there is "regular" motor
output; if _motor_controller is the BrickOS value of 0x80, DCC motor output
functions as expected.

After all the amazing post across lugnet the past few weeks, it feels
a bit lame putting this one up:
http://rubyredbricks.com/2009/4/27/simple-traffic-light
I guess once it's running up on an RCX it'll be a bit more interesting.
On the topic of RCX - and the whole old-school Mindstorms
preservation idea - I haven't forgotten about it. I've registered a
domain and will aim to get a wiki up and running over the weekend.
Cheers

Hey folks
I've created a very basic site here: http://www.rcxzone.com/
When I say very basic I mean VERY basic.. it's just an empty instance
of mediawiki, but I'll look to adding content when I get a chance.
Any help appreciated.
Cheers
Tom
