Hi!
>So, does anybody know how difficult it would be to support Localtalk
>(i.e. Appletalk over a serial line).
The hardest part probably is the hardware. The Mac uses a Zilog USART
while most PCs only have an UART (not capable of doing synchronous
transfers). The next problem probably is speed. localtalk runs at 307
kbaud. On the Mac they have to use polling of the USART to achieve
this speed.
So to get is working on a PC you probably need some special hardware
containing a Zilog USART and a processor doing the polling.
