1. Implement new system and disk subsystem configuration mechanism.
2. Implement initial Mark-XIII Cold Start card deck for use with new configuration interfaces.
3. Deprecate use of B5500ColdLoader.html script (replaced by new configuration mechanism and Cold Start deck), but correct and enhance IndexedDB database detection, creation, and deletion in it.
4. Implement "Application Cache" support to allow emulator to run off-line in a browser.
5. Implement web-font support and update all UIs to use DejaVu Sans and DejaVu Sans Mono from downloaded .woff or .ttf font files.
6. Rework some code in Processor OPDC, DESC, and indexDescriptor routines, attempting to resolve Flag Bit errors (issue #23). This appears to result in some improvement, but we still see them occasionally under load.
7. Line Printer:
- Implement new line printer driver with more realistic UI and operator controls.
- Implement Algol Glyphs option to render special Algol characters in Unicode.
- Implement support for optional "greenbar" shading on the "paper".
8. SPO:
- Redesign SPO driver to accept input from a text <input> element instead of capturing keystrokes directly from the window or "paper" <iframe>. This was done to allow input from tablet and mobile devices that will not pop up a keyboard unless an input-like element has the focus.
- Implement Unicode Algol Glyphs support on output.
- Intelligently resize "paper" area when SPO window is resized.
- Accept "_" as a substitute for "~" as end-of-message on input.
9. Card Punch:
- Implement Unicode Algol Glyphs support on output.
- Implement stacker-full annunciators in UI.
10. Card Reader:
- Implement Unicode Algol Glyphs support on input.
- Accept "_" as a substitute for "~" on input.
11. Disk:
- Adapt B5500DiskUnit driver to new configuration mechanism.
- Implement support for Model-IB (slow) disk and non-DFX disk storage configurations; support up to 20 EUs.
- Implement check for DKA readiness in cc.load() if not doing card-load-select.
12. Datacom:
- Rework datacom driver keystroke handling for compatibility with Google Chrome.
- Correct typo (line 437) in B5500DatacomUnit reported by Peter Grootswagers (issue #28).
13. Magnetic Tape:
- Implement more granular tape reel animation in B5500MagTapeDrive.
- Open the tape loader window on top of its device window.
14. Correct color of NOT READY lamps in peripheral device UIs; convert <progress> bars to <meter> elements.
15. More intelligently resize peripheral UI controls when their window is resized.
16. Implement lamp test during power-on in B5500Console.
17. Illuminate NOT READY light on Console at power-on if certain minimum configuration requirements are not met.
18. Set all HTML <meta> Content-Type character sets to UTF-8 (were ISO-8859-1); correct problem with FireFox requiring the character set to be specified within the first 1024 characters of an HTML file.
19. Clean up and refactor CSS style sheets
20. Split Javascript code out from B5500Console.html to new B5500Console.js.
21. Refactor common UI routines into webUI\B5500Util.js.
22. Move images and fonts to new webUI/resources directory; rearrange files in webUI/tool, tools, tests, source directories of repo.
23. Make significant wiki updates to document the new features in this release.
2. Fully implement Double Precision Add/Subtract (DLA/DLS), Multiply (DLM), and Divide (DLD) syllables.
3. Replace standard setTimeout() by redesigned setCallback() mechanism throughout the emulator for scheduling timing delays and other callbacks on the Javascript thread. Delete obsolete setImmediate() mechanism.
4. Replace "new Date().getTime()" by "performance.now()" calls for greater timer precision.
5. Minor tweaks to Single Precision arithmetic operators.
6. Replace Javascript postfix operators by prefix operators wherever feasible (e.g., x++ becomes ++x).
8. Attempt to correct character translation and keyboard filtering in DatacomUnit for CANDE.
9. Minor changes to button colors and illumination behavior for I/O devices and Console.
10. Suppress I/O device classes in B5500SyllableDebugger by default (uncomment in source to enable).
. Drop support for webkitIndexedDB and mozIndexedDB (for now).
. Configure four tape drives (MTA-MTD) by default.
1. Initial implementation of a datacom terminal.
2. Initial implementation (read-only) of magnetic tape drives.
3. Further work towards getting P2 to function (but not working yet).
4. Allow device driver classes to be optionally included in the global UI script.
5. Fix callback arguments handling in SetCallback.
6. Decrease width of SPO window slightly.
7. Improve trapping and printing of SPO keystrokes, based on datacom implementation.
8. Minor performance tuning improvements.
9. Dump raw header words in octal in tools/B5500DiskDirList.html script.
10. New wiki pages and several updates to existing ones.
2. Implement new setCallback() mechanism to wrap setTimeout() and setImmediate().
2. Minor change to P2 management; remove context-bound callbacks.
3. Reduce window size and font size for peripheral UIs.
4. Implement <label> for file names on ColdLoader Load table.
5. Correct placement and color of buttons on Console and SPO.
6. Minor wiki updates for UI changes.
7. Rework SPO implementation to eliminate ".that" properties, implement setCallback(), and fix long-standing bugs that caused flaky operation.
2. Implement interrupt and device status latching in B5500CentralControl to support better UI display.
3. Implement B5500CardPunch device.
4. Implement preliminary and experimental B5500DummyPrinter device; correct printer I/O initiation in IOUnit.
5. Correct the way that Printer Finished interrupts are handled in IOUnit and CentralControl.
6. Implement Card Load Select in B5500Console and B5500SyllableDebugger.
7. Fix lack of presence-bit detection in return ops for returned values.
8. Redesign B5500CardReader UI to show last two cards read; change method of emptying the input hopper.
9. Set CHECK option and rework SYSTEM/LOG initialization in B5500ColdLoader.html.
10. Centralize system memory cycle time setting; change from 6us to 4us memory cycle time.
11. Increase Processor timeslice to 16ms and rework Processor.schedule() internals for more accurate performance throttling in browsers with poor setTimeout() granularity.
12. Reduce Processor syllable overhead from 2 cycles to 1.
13. Change B5500SPOUnit method of output to "paper" to work better in Google Chrome.
14. Make documentation and debugging enhancements in B5500IOUnit.
15. Release initial test website HTML and Unisys license PDF.
16. Commit Mark XVI DCMCP transcription as of 2013-06-21.
