uCOS-II

I may be late to this party, but was wondering if uCOS is still free? 
Read about it on the rabbit pages, and also was reading about it being 
open, but after going to the 'main site' to get more details before i go 
out and buy the book, it only looks commercial now.

If it is now a commercial product, any one have recommendations for a 
really small free RTkernel that would mate well to a z80 and rabbit 
2000?  ( perhaps even a 8051, but i know thats a stretch due to the 
radically different architecture ).

The 'target' will be doing simple monitoring of sensors and changing of 
remote parameters from a serial port based human interface ( i.e., palm 
pilot ) so i dont need anything fancy, but didn't want to 'do it myself'.

Only for personal use.

There's a fee for commercial use, but it isn't
particularly large.

If this ever became a commercial product the fee wouldn't be a problem 
as it would just be passed to the customer.  How do you 'register' to 
get the nocomm copy? or do i just need to go buy the book?  I guess 40 
bucks isnt much to waste if i don't like his code...

The licensing terms for the uc/OS kernel distributed with the first
edition of the book make its use free even for commercial applications
as long as you do supply the kernel only in object form.
May be you can find a copy of the 1st ed and use that version.
On the other hand, that may have been an x86 only version.

Have a look here:

Salvo is free, but it seems to work on just about everything except the
Rabbit.

After posting that, I remembered that Intel put their old real time
kernels for 8080s and 8051s (different products, not one product
ported to both architectures) in the public domain.

While looking for them (did not find them yet) I found this:

For the 8051, I found a copy of DCX51 here:
http://www.dtweed.com/circuitcellar/ftp_area/areacro2.html
(there are other goodies worth checking in that page.)

It seems I was mistaken in my believe that the 8080 real time kernel
was also in the public domain. The IRMX product line was sold to
Tenasys ( http://www.tenasys.com/products/irmx.php8 ).
They still sell descendants of IRMX-86, but I couldn't find any
reference to a free download version of RMX-80.

You Buy the Book You Get a Personal Copy.  You Pay the Fee You get the 
Latest Version.  The Book Version Works fine.  There are ports available 
on the net and at the micrium (I hope that is spelled right) web site.
There is 1 CPU specific file.  BTW uCOS-II is a little heavy for the 
8052.  It works, but there is not much left for very many tasks.

And this http://www.marathon.ru/~fedor/doc/osdesign/kernels/, with 
several RTOS's.
