. Adjust (hopefully for the last time) the RGB code for the 220
Sundland Beige panel color: it's now #C5B1A0. This has been a really
difficult color to pin down.
. Implement Clear Memory button on Console; implement "hover captions"
for the Clear Memory and Load Card buttons.
. Implement current block-number display on magnetic tape panel.
. Implement "word index" counter on the B220MagTapeDrive panel to
indicate the tape position in terms of 11-digit 220 words.
. Implement Rewind and Unload buttons on the paper-tape reader.
. Implement "word index" counter on the B220PaperTapeReader panel.
. When a Cardatron or paper-tape reader encounters a sign=6 control
word, do not reschedule the Processor if it has been halted.
. Correct handling of reload-lockout in B220CardatronInput; change
method of reporting Cardatron end-of-I/O signal to the Processor.
. Correct this.pendingFinish timing race in B220CardatronOutput.
. Correct validation when loading tape images in B220MagTapeDrive so
that the drive will continue to be usable after an invalid image is
detected.
. Correct logic for spacing and searching magnetic tape blocks
backwards.
. Correct output of non-printing characters in B220PaperTapePunch.
. Correct handling of invalid tape image characters in
B220PaperTapeReader.
. Implement additional tracing for paper-tape and magnetic tape I/Os
(currently disabled).

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. Commit initial (incomplete) implementation of magnetic tape drives (TSU) and control: MLS, MRW, MDA, MIW, MIR, MPF, MPB, MPE, MIB, MIE.
2. Change B220SetCallback.js "setImmediate" mechanism to use DOM Promises instead of window.postMessage().
3. Minor styling and window positioning changes.
1. Initial Cardatron implementation with CardatronInput (card reader).
2. Implement default Pi demo program at address 0300.
3. Implement WINTER.PI card-load deck to boot from card reader 1 and run at address 0500.
4. Fix syntax typos in tools/BAC-Assembler.html.
1. Implement console teletype printer and paper tape punch devices.
2. Correct timing mechanism and operation complete processing for asynchronous (I/O) processor mode.
3. Delete extraneous alarm toggles from B220Processor.
4. Correct Reset And Transfer switch so it will work when the Processor is running.
