Revision: 1.12
Committed: 2004-11-13T14:09:15Z (19 years, 6 months ago) by gbeauche
Branch: MAIN
Changes since 1.11: +39 -39 lines
Log Message: 
Implement Direct Addressing mode similarly to Basilisk II. This is to get
SheepShaver working on OSes that don't support maipping of Low Memory globals
at 0x00000000, e.g. Windows.
