1. Rework Processor internal timing and throttling mechanism during I/O.
2. Revise Console statistics display, add instruction counter.
3. Correct (again) CFA/CFR instruction when sign is included in field.
4. Correct B-register modification of words during Cardatron and
magnetic tape input.
5. Clear Processor alarms on Reset/Transfer.
6. Add links to wiki on index and home pages.
7. Eliminate B220Util CSS class functions in favor of DOM classList
methods.
8. Attempt to reproduce "Sundland Beige" color for the panels.
9. Correct formatting of tab stops for B220ConsolePrinter.
10. Reduce Whippet printer speed from 5000 to 1000 cps.
11. Reduce Console update frequency from every 50 to 100 ms; increase
lamp glow update factor from 0.25 to 0.75.
12. Allow click of white button below console register lamps in addition
to clicking the lamps themselves to toggle the lamp state.
13. Rework the way that white vertical bars are drawn on registers.
14. Allow B220PaperTapeReader to properly send sign-2 alphanumeric words
with trailing spaces if the tape image file has been space-trimmed on
the right.
15. Clear the paper tape reader view window when loading new tapes.
16. Revise yet again the setCallback() delay deviation adjustment
algorithm.
1. Correct scaling and normalization limiter errors in floating Add/Subtract uncovered by BALGOL testing; set Single-Step instead of Stop if normalization limiter is exceeded.
2. Correct improper comparison of sign digits by CFA/CFR uncovered by BALGOL testing.
3. Change method of lamp glow update in Processor and ControlConsole to provide smoother, more realistic display.
4. Implement diagnostic trace facility in Processor; toggle on and off by double-clicking "220" logo on ControlConsole.
5. Implement temporary, experimental floatingAdd() routine in Processor that does rounding for use in BALGOL validity checking (the 220 did not round, and it is disabled in this commit).
6. Correct printer carriage control handling in CardatronOutput.
7. Improve timing for ConsolePrinter TTY "Whippet mode".
8. Implement compression of consecutive duplicate blocks in tape image files for MagTapeDrive -- see comments in source.
9. Remove inappropriate SPO selection from unit designate on PaperTapeReader panel.
1. Rework magnetic tape drive implementation to use Promises; refactor and consolidate drive operation routines.
2. Implement remaining magnetic tape operations: MOW, MOR, MRD, MRR, MTS, MFS, MTC, MFC.
3. Implement better error status reporting in mag tape control MISC register.
4. Implement memory and Processor-state dump by clicking the Burroughs "meatball" logo.
5. Implement preliminary run-time statistics on Console.
6. Use Function.bind() to bind context in Processor and mag tape scripts.
