Yes. When building embedded systems, is it very rare that 'portability' 
be on the top of any requirements list.

In fact, here (to my own dismay) Ada is in the opposite side: it is very 
hard to find Ada development tools for a lot of popular microcontrollers�.

Our message could have promoted Ada as a better way of developing such 
systems and emphasizing the advantages of it.

Two mistakes don't make a good result!

To our chagrin (Ada professionals) a lot of "RT embedded SW" is made 
with those less than safe (and incomplete tools) but we have to accept 
this and see better ways of sending our message out.

The arrogance I felt in your repply stems of an interpetration that 
anyone not having knowledge of Ada should not dare to write a book about 
on RT embedded SW, which besides being prejudicial is non sense.

A lot of people could bring to this thread a lot of counter examples of 
systems built in Ada which have been plagued by errors (some of IMNSHO 
could have been avoided by better use of Ada technology and practices it 
facilitates).

[1] I sent a private e-mail to OP asking what chips he intends to use in 
the examples but still did receive any repply. Depending upon the 
technology mentioning Ada would be somewhat pointless.
