Would anyone care to enlighten me as to the ins and outs of Macintosh
networking?  I work in a small company where there are two Mac IIs and
a Mac Plus being used.  We'd like to hook them together to increase
their usefulness.  We're starting pretty much from scratch; the only
other equipment that will probably come in handy are two Nuvotech 
TurboNet boxes (that we used to hook one of the Mac IIs to a visiting
LaserWriter awhile ago).

Our needs are:
  a) NO SERVERS - We're not rich (yet), and we'd all like to continue
     using the machines that we have.  This rules out AppleShare, I 
     guess...

  b) share files - Two of us develop software, and often work on the
     same project.  Right now, we both maintain copies of the sources
     on both machines, with one of us integrating his changes into the
     master source.  This is a pain, and my being able to change files
     on the other machine would be quite helpful.

  c) messaging - Something like Broadcast would probably do.  Real email
     would be even better.

  d) sharing printer(s) - See (a).  We're not rich (yet), and all we have
     here now is a couple of Imagewriters.  Is there an alternative to
     upgrading one or both to be Appletalk Imagewriters?  (Would such a
     solution require enough of the CPU that we'd want to upgrade the
     Imagewriters so that the person printing would be talking directly
     to the printer.)

  e) hook up other machines - Eventually we'd might like to hook up an
     IBM clone to this network.  Not a big consideration...  We also have
     an old Alpha Micro machine with a bunch of disk space that we could
     use for archival storage, if hooking up were not too much a problem.

So, the question of the day - what hardware and software do we need? 

By eliminating AppleShare because of (a) above, it looks to me like that
leaves Tops and something called "Personal Server Network" from Information
Presentation Technologies, Inc.  Can anyone give me the pros and cons of
choosing one over the other?  I'm tending to lean towards PSN because I've
heard that they adhere to AFP, where Tops has it's own protocol.

And that leaves me to solve (c), (d), and (e) with other hardware/software.
Any suggestions for email for a small set of machines?  Network print
spoolers?

Thanks for any help you can offer.
