Ahh yes, the good old A5000, mines sat right beside me now.
It powers up, but only just, I will get around to soldering a new CMOS chip into it at some stage.
A500, Iv'e heard of but never seen one in the Wild.
My original copy of the DDE was free too, I was working on a project for a company at the time, and as part of my payment they paid for and furnished me with my own personal copy.
As for what does it do.. well
If it's like the version I have, then you'll have
C-Module Header Generator
Plus all the acorn specific headers and includes with libs in C and ASM source
As it's the newer version, you might well also have all the toolbox tools, such as the editor, tester and resource generators too.
still crazy (Even since the days of my BBC Model B) BEST and only way to be
