[comp.sys.mac] Tops question

planting@sun6.cs.pittsburgh.edu (Dr. Harry Plantinga) (08/17/88)

I would like to share files between a Sun and a mac plus.  I understand
that Tops is a good package for that.  What do I have to do to connect
the mac to the sun, besides ordering Tops?  Is appletalk required?  Is
localtalk available for the Sun?  Is an ethernet connection available
for the mac +?  Or would I need some sort of localtalk/ethernet gateway
box?

SUN will tell you to connect via EtherNet cable, and get a Kinetics box 
for the Macintosh.  You can then transfer files over TOPS via EtherTalk, 
the EtherNet implementation of AppleTalk.  To me this sounds like 
overkill because a two machine EtherNet will NOT be significantly faster 
than a two machine AppleTalk network, especially if the Mac is an SE or 
Plus.  My timings indicate that speed increases of only 20-30% are 
observable in file transfer when comparing small ethernet vs. appletalk 
networks with low loading.  There is an alternative to the Kinetics box 
called the Gatorbox, but I have no experience with it.  
Unfortunately, an AppleTalk card for SUN will probably run you as much as 
a Kinetics or Gator box, unless it's a 386i, in which case you MAY be 
able to utilize a TOPS PC Card.
