Anybody know offhand if it's possible to use AppleTalk on a Hayes
Transet? It apparently has a 68008 and 8530 SCC in it, it's
possible to program the 68008, and the price is right.
This would be a neat way to build a networked modem and printer box.
Too bad only one of the ports is set up for RS-422.

I have a Hayes Transet 1000 at home. It is a printer buffer, printer
to 2 computer interface, 2 computer to printer interface, serial to
parallel converter, computer to 2 modems, 2 computers to 1 modem,
unattended mail collector, <etc> thingy.
It is a 68008, may be user configured with Hayes AT commands or loaded
*directly* with 68000 code, contains either 128kb or 512kb RAM, 3
serial ports, 1 parallel port, clock. List price for the 128kb version
is $400 but may be had discounted for well under $300. It physically
looks just like the Hayes 2400 Smartmodem (case and external power
supply), but has a different array of LEDs with 4 buttons in front and
1 male 9-pin, 1 female 9-pin, and 1 15-pin connector in the rear.

I don't know if the 128k version can be user upgraded. I have not taken
mine apart yet. If it can, you may have to replace the external wall
mounted transformer with a larger one. Sorry, I just don't know.
You might call Hayes customer support (sorry again, I don't have the
number but it is included in many of their ads or in the Norcross, GA
404 area code phone book). They answered my original questions about
the thing before I bought it.
As to the parallel port - it is one direction only... intended for
Centronics interface printers.
One interesting thing I just discovered from the manual is that one
of the serial ports supports differential (aka RS-422) signals as well
as RS-232.
Hope this helps. Regards.

RS-422 does sound interesting. If Hayes uses the Zilog 8530 SCC, then it
might be possible to run AppleTalk over the thing. (since they're using a
68000 public-domain AppleTalk code should be easy to come by.)
One could use a Transet box to add a 'networked' modem and printer to a Mac
network. Pretty neat, if its possible.
