15fc6c5a0b 1. Finalize and release emulator version 0.05.
2. Fix (we hope) the nasty problem that was causing Invalid Address out of COM5 after large compiles -- bug in MSCW/MSFF tracing in Processor.exitSubroutine().
3. Implement ability to do a hardware load without initiating P1 in CentralControl (used by SyllableDebugger).
4. De-anonymize object prototype method functions in Processor as an aid when using JS debuggers.
5. Rework storeForInterrupt() and initiate() in Processor.
6. Replace bitmask "AND"s with power-of-two "MOD"s in many places in Processor.
7. Replace many bit(), fieldIsolate(), fieldInsert() calls with mod/div expressions in Processor.
8. Fix a problem existing normalization when an Integer Overflow occurs in Integer Store syllables.
9. Fix missing and superfluous break statements in Processor.run() switch statements.
10. Fix incorrect C-register restoration in Character Mode RCA syllable.
11. Correct test for continuity bit in Processor PRL syllable coding.
12. Correct missing "this." in Processor BRT syllable coding.
13. Change way that delayTime and Processor.procSlack is computed in Processor.run().
14. Correct BCL translation bug and directory EOF detection in B5500ColdLoader.
15. Attempt to initialize SYSTEM/LOG in B5500ColdLoader (not working yet).
16. Implement new retro-B5500-Logo.png.
17. Implement Hardware Load button in SyllableDebugger.
18. Release tools/B5500DiskDirList.html utility.

3db6111394 1. Commit version 0.03 of emulator and tools: this version successfully performs a hardware load from the disk and initiates the MCP.
2. Redesign B5500Console.html to support the Power On, Power Off, Halt, and Load buttons, along with a primitive mechanism to drive the Normal/Control lights.
3. Implement relative URLs for the <script> elements. This is a work in progress.
4. Commit Nigel's fix for the annoying problem with Firefox where typing "/" on the SPO brings up a QuickFind dialog.
