. 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. Correct PRD (03) to properly recognize control words on the tape
when B-modification of the input is also being done.
2. Temporarily add custom tracing of PRD, PRB, and PRI instructions.
3. Implement word counter on paper-tape panel to show current position
in the tape image.
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. Implementation Paper Tape Reader devices and op codes.
2. Commit standard and inverse-format paper tape loaders for WINTER.PI program.
3. Fix positioning of Cardatron and TTY/Paper Tape Punch device windows.
