[comp.sys.mac.hardware] How to do Twisted Pair on new Macs

acmpres@zeus.unomaha.edu (Dave Caplinger, Microcomputer Specialist) (09/29/90)

Here's some wishful thinking for you... (Apple, please surprise the heck
out of me and have had the foresight to do this!) 

With respect to Ethernet-on-board, consider the serial port on the back
of your Mac.  Also, consider the port on the ImageWriter II.  It can
accept either "ImageWriter Speak" or "AppleTalk ImageWriter Speak",
which are in fact different (try printing to a non-AppleTalk ImageWriter
as a "AppleTalk I..." (as it looks in Chooser).  Same port, different
logic, different protocols. 

Now about that Twisted-Pair Ethernet... who's to say that it's not
possible for some software (i.e. device driver) to switch the serial
port not just between "serial speak" (as to a Modem, fax, or
non-AppleTalk printer) and "AppleTalk speak", but also to "TwistedTalk
EtherSpeak" or whatever. Wires are wires, I guess.  So what if most of
them aren't used for TwistedTalk, or that you might need a different
connector box. 

Better yet, wouldn't it be great if this was already built into the new
Macs, and once the Standard Committee has given 10baseT it's blessing,
Apple can say "oh well guess what!  It's already implemented, and since
we took so long getting System 7.0 out the door, the driver for it is
included with Sys 7." 

It's really can't be all that hard to figure out what the "blessed"
standard is going to be; Farallon already guarantees that their products
will work with 10baseT, right? :-) 

Go for it, Apple.  Surprise us.  Hell, if you do this, you'll probably
surprise just about everyone.  :-)
