A few months ago I was looking for a synchronous serial comm adaptor for
the Mac II and struck out, both here on the net and via our friendly Apple
contact. The need has come back in spades, have I missed any product
announcements recently? I would appreciate information.
One comment previously was that the Mac serial chip could itself be
programmed to run in synchronous mode, and that therefore a CI adaptor
board is not necessary. Other opinion maintains that system considerations,
i.e. real time constraints, prevent the comm chip from running at high
speeds (64 kbps) synchronously. On the third hand, it obviously can run
Appletalk (async?) at high speeds. Any comments?
Thanks in advance, Dick Jackson
