Appletalk (actually LocalTalk) electrical spec uses the Synchronous Data Link
Control (SDLC) protocol. The signalling is based on EIA RS-422, so you would
have to build a circuit to convert from the RS-232C signalling protocol to RS-
422. Actually that wouldn't work well, becuase the effective data rate is
around 230Kbits/second. I doubt very much if the internal serial port could
keep up with that data rate even on accelerated machines.

The networking protocols including the  printer access protocol are quite
involved and complicated, not quite a weekend software hacking project I'd
say.

If you're interested in AppleTalk pick up the book called: Inside AppleTalk,
second edition, Addison Wesley.

Also, I do recall seeing a posting about AppleTalk for the Amiga, and I even
managed to drudge it up from my archives... Here's the article:

The Hydra systems/GVP Ethernet AmigaNet network is a real fast peer-to-peer
network solution for the Amiga.  It doesn't work with 2.0, however.  AmigaNet
for 1.3 is exactly what anyone could ever want in an Amiga networking
solution,
with the exception of the lack of a NetBios level interface.  The NetBios
interface
would allow for developers access to network level communication between
machines...

Welp, if you REALLY Must connect your machines via AppleTalk, there is a
company called DigiFex in Oregon that makes a product for the A500 and A2000
that allows you to link into a AppleTalk system and share printers, transfer
files, etc.....I tested a system for awhile and didn't care for it all that
much, was really slow....  However, its about your only choice that I know of.

AppleTalk is only 230Kbps, so it's not a speed demon.  It _is_ faster than
your floppy ;-).

Forget about DigiFeX... I own all rights to the code, and will be marketing
it through CSA (with an 040 attached).  I am redesigning it, and doing some
extreme improvement in interrupt handling which will mean less packet
collision.  Interact is an unsupported product, as is all of the rest of
CMI's projects that DigiFeX took over.  The only product that they are
currently selling is the V.I.P. (Video Interface Professional).

Yeh, I modified that to work with my BBX.  Nice program, too bad you made
the new version C-Net specific P-Files (or whatever they're called).  If
you want to see it in action (along with the FF disks on ROM ;-) call.  Ok,
so it was a plug... in the wrong area no less... sorry.
