1. Implement new single-precision add/subtract routine that more closely follows the real B5500 logic.
2. Implement tests/B5500SPMathTest.html testbed to exercise the new add/subtract implementation.
3. Implement new way to focus the ConsolePanel window after the SPO becomes ready during initialization.
4. Add "?db=" parameter to tools/B5500DeleteStorageDB.html to specify the disk storage data base name.
5. Implement "Execute Single" button in B5500SyllableDebugger to preserve the T register when testing a single syllable.
6. Implement "octize" and "pic*" function in B5500Util to support tests/B5500SPMathTest.html.
7. Commit minor changes to webSite index page and GitHub README.md.
Commit version 1.03b:
1. Remove initial window open/close (to destroy any existing windows) from Console, I/O device classes, and configuration utilities.
2. Commit Mark XV MESAGE/CANDE file for reconstructed SYSTEM tape, donated by Rich Cornwell.
Commit version 1.03a:
1. Correct character translation for even-parity tape operations.
2. Implement normal tape space operation for tape maintenance space operation (temporary solution to fix problem with Mark XV tape parity recovery -- Mark XIII did not issue maintenance space I/Os).
3. Modify B5500MagTapeDrive to report EOF+parity when attempting to ready beyond the end of the internal tape image (previously reported only parity error).
4. Restate B5500Processor delay deviation and processor slack time average calculations and increase the alpha for the running exponential averages to smooth out the reporting on the B5500ConsolePanel.
5. Improve delay timing calculation for B5500CardPunch, B5500CardReader. and B5500LinePrinter.
1. Alter method of writing disk sectors to IndexedDB, to avoid dragging along the entire 16KB IO Unit buffer area and unintentionally inflating host disk usage by 30-60X (ouch). This was causing Quota Exceeded errors in recent versions of Firefox.
2. Add onabort traps in B5500DiskUnit to catch QuotaExceeded errors.
3. Modify delay-deviation adjustment mechanism in B5500SetCallback to avoid oscillating between positive and negative cumulative deviations.
4. Correct tape reel angular motion in B5500MagTapeDrive, especially during reverse tape movement.
5. Fix bug with reporting memory parity error during tape I/O, should that ever occur.
6. Reset CPA Algol Glyphs option in default system configuration template.
7. Allow tools/B5500LibMaintDecoder to examine an entire .bcd tape image file instead of just the first 64KB.
8. Add USE SAVEPBT to default options in tools/COLDSTART-XIII deck.
9. Eliminate extraneous "schema update successful" alert when altering a disk subsystem configuration.
10. Commit minor corrections to source/B65ESPOL/SOURCE.alg_m from Richard Fehlinger.
1. Move project from Google Code to GitHub (https://github.com/pkimpel/retro-b5500/). Update links and help pages; convert wiki pages to GitHub's MarkDown format.
2. Implement emulator-hosted memory dump to a tape image that can be saved and input into the B5500 DUMP/ANALYZE utility for analysis. Activated by clicking the NOT READY button on the Console.
3. Fix bad assignments to Processor X register in arithmetic ops (affected only SyllableDebugger script).
4. Remove IndexedDB.openDatabase() version parameter so the B5500ColdLoader and tools/ scripts will work in non-Firefox browsers.
5. Add a "?db" query string parameter to the tools/scripts so these scripts can open disk subsystems other than B5500DiskUnit.
6. Correct pre-allocated file locations and ESU card in tools/COLDSTART-XIII.card.
7. Implement new double-click mechanism to copy and clear the contents of card punch, datacom terminal, and line-printer output areas to a temporary window for subsequent copying or saving.
8. Correct handling of Ctrl-B (break), Ctrl-D (disconnect request), Ctrl-E (WRU), Ctrl-L (clear input buffer), and Ctrl-Q (alternate end-of-message) in B5500DatacomUnit.
9. Implement reporting of Model IB (slow, bulk) disk in B5500DiskUnit readInterrogate.
10. Implement detection of browser IndexedDB quota-exceeded errors in B5500DiskUnit (primarily to handle the fixed 2GB limit for off-line storage in Firefox).
11. Correct problem when line printer exhausted paper and FORM FEED triple-click did not clear the condition.
12. Eliminate BOT marker sensed in result for tape drive Write Interrogate operation -- Mark XIII and XV MCPs treat this as an error and will not purge blank tapes because of it.
13. Fix double-click of SPO INPUT REQUEST button either sending a duplicate interrupt to the system or the second click moving focus from the SPO input box.
14. Further tuning of delay-deviation adjustment mechanism in B5500SetCallback.js.
15. Reinstate ability of SPO to wrap long outputs to additional lines (apparently lost with new SPO input mechanism in 1.00).
16. Commit preliminary COOLSTART-XIII.card and MCPTAPEDISK-XIII.card decks.
