. 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).
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.
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.
