Thanks for the suggestion.
I've actually got my eye on the 18f252.
Can you give me an idea on how /well/ it's supported by sdcc?
The only thing I've done with sdcc on the 876 so far is run a LED
counter prog, and I've not gone any further because I've had the feeling
that 876 support is not 100%. At the moment, using CCS (pseudo-)C compiler.
Are you saying that sdcc supports the 18f chips better than it does the
16f chips? Is it mature enough for real 18f development? Is its
optimiser up to scratch? Is it trustworthy with respect to generating
bank-switching code, etc?
