- If you don't need really high performance, you could always use
- Appletalk (localtalk) instead - all you need is a serial controller
- that can do HDLC, and the bandwidth is low enough (1/4 megabit) so
- that a lower-speed micro can handle it.
-
- There are at least 4 microcontrollers I know that you could use for
- this - two 16-bit ones (68302, and one by Nat'l that I forget the name
- of), and two 8-bit ones (Z181, and one that's an 8051+HDLC). I'm sure
- there are others.
-
- Of course you'd have to write the media access control code, which
- would be a pain, although the algorithm is pretty well documented in
- Inside Appletalk. At least you'd be able to test it against known
- working implementations.
-
- [actually, I've wondered whether there would be a market for Localtalk
- code for an embedded micro. I was once told by someone at Shiva that
- they use such a beast (the 8051 derivative) for their Localtalk
- products, but I doubt they'd be interested in sharing their code :-)]
