2. Fix normalization and rounding problems in Processor. 3. Fix Card-Load-Select -- emulator now boots from cards. 4. Commit LDCNTRL label and end cards to source CONTROL.DECK.job 5. Delete unused activeIOUnit property in all I/O drivers. 6. Change CardReader to reset file selector control when hopper becomes empty, instead of when START button is clicked. 7. Minor adjustments to CentralControl annunciator layout and behavior on Console. 8. Increase SPO paper scroll-back to 1500 lines (was 500). 9. Correct Card-Load-Select behavior in SyllableDebugger. 10. Implement setCallback() to replace setImmediate() in SyllableDebugger.
