Anyway.....) Their exixts a daughterboard made by Ironwood Electronics, of Minneapolis, Minnesota, that fixes the paging problem on the 6386 machines. The board, called the Fix-386, is about the same size as an 80386 and is placed into the 80386 socket. The 80386 is then plugged into the Ironwood daughterboard. Fix-386 is available directly from the manufacturer as part number FX-PGA 132-01. The list price of the board is $145, but AT&T referrals will receive a 25% discount. To order the Fix-386, contact: Ironwood Electronics Attention: Paul Jasmin P. O. Box 21-151 St. Paul, MN 55121 Ted Myslinski
