I do not know the specifics of how exactly this works (someone want to jump in here), but I know that there are several companies who are running our product over TCP/IP out to their IBM through a ACC (or some such) and doing multiple 3270 sessions on their Mac. TCP/Connect supports 3278 models 2,3,4,5 and Brown has a PD version of 3179g emulation that will support one session at a time. As far as I can tell, using a ACC (or whatever) box is just about the standard way of doing what you want.

Suggestions, anyone? > > /kenw You might also think about two other possibilities: 1) TriData makes a box called the Netway 2000 which connects to the 3174 and then to AppleTalk and distributes (so they say) up to 16 AppleTalk 3270 sessions. 2) Apple just introduced a 3270 card and MacDFT which is 3270 terminal emulation for the Mac. Each card would go into the Mac II and then connect directly to the 3174. Hope this helps. Tim Enwall
