Steven Wallace 234cc877a2 Import of original NetBSD's ibcs2 emulator sources by Scott Bartram, 
which is used as a basis for a more complete and cleaner ibcs2 emulator.
(snapshot about May 1995 with a few files from September 1995)

Some files and code from old emulator still remains.
New files, features, and changes have been implemented by myself,
which will be shown in following commits.
