Sigh..... Things just change too fast......
And tho I (quickly) checked the usual archives, I couldn't find an included
MacTCP 1.1.1.  

   Not to take this discussion too far afield, but because this will
probably affect a number of Mac users as they upgrade to Sys 7.1 and
beyond, I include the following correspondence that might throw some light
on this subject.

I am not sure Netiquette allows reposting of mail from another list. Should it
*be* OK, please post the following to I-M Digest (reminder: my .sig is 145
bytes long, but you may delete all but the 1st line should you deem it
necessary), originally on the 'eudora` list. Thanks.

Here is what Steve Dorner had to say about the MacTCP affair:
