Basically, it sounds like you want a Macintosh to gain access to a DOS EIS
application running on a Novell Server, via a "PC Gateway". Conceptually, this
sounds feasible. However, it would be prudent to test this configuration.
From a memory standpoint, you should be okay. The AppleShare PC software can
be pared to 50K or so. The Novell software requires a little more room,
perhaps as much as 80K or 90K. Those memory requirements combined with DOS
(roughly 100K) still leaves 400K (640-50-90-100=400) for the application.
Even if you do run short of memory, third-party cards and programs may help you
work around the limitation. Two such products are HiCard and MOVE'EM
(information on each is in the Tech Info Library).
The minimum AppleShare PC drivers needed are LSL.COM, LTALKP.COM, ATALK.COM,
and COMPAT.COM.
