Awesome! The RKM:Libraries reference was exactly
what I was looking for. Thanks for the tip Zetr0.
I found an online version on the same site Steve mentioned (thankyou!) - here
I might see if I can also dig up a hardcopy as it looks to be a great reference.
The hardware reference will be really useful too. I'm slowly starting to get my head around the architecture a little.
If anybody else has any additional references that they think may be handy, please do still let me know.
Thanks again for the assistance so far, and the warm welcome
