[comp.sys.zenith.z100] MS-DOS 3.1 Discount for Z-100?

elder@WPAFB-INFO5.AF.MIL (06/25/89)

The first issue of "Z-100 Lifeline" mentioned that there probably
was a discount available from Zenith to acquire MS-DOS 3.1 for the Z-100
for only $49.00.  I wrote Zenith and their reply was that there did
not exist any such discount.  I was just wondering if anybody else
knew of anyplace which sold MS-DOS 3.1 for the Z-100 (but at a price
less than $195.00, which is what the Zenith standard price is)?  I
would like to upgrade from 2.18 but don't want to spend that kind of
money.

   Thanks.
