4. Strip sign digit from search/scan argument word when storing into B220MagTapeControl T register.
5. Remove option for 1000-word system memory size and correct handling of memory size list selection in B220SystemConfig.
6. Change reel-to-reel magnetic tape name from DataReader to TSU in B220SystemConfig.
1. Remove Application Cache mechanism (has been deprecated as a web standard).
2. Replace internal bindMethod() utility function with standard Javascript object.bind().
3. Automatically reset Digit Check Alarm when bits are corrected in registers.
4. Correct setting of Overflow Toggle in IFL.
5. Terminate magnetic tape data transfer if AST toggle gets reset.
6. Correct way Processor was released by magnetic tape TCU.
7. Correct construction of preface word in memory for mag tape MRR.
8. Correct determination of mag tape "remote" status to allow tape to be unloaded immediately after a rewind.
9. Fix bug in BCS detecting the switch setting.
10. Modify behavior of Reset/Transfer switch to allow recovery after a tape malfunction.
11. Correct formatting of HIGH lamp on Control Console.
12. Remove extraneous whitespace from B220FramePaper sub-window markup.
1. Minor improvements to magnetic tape implementation and rearrangement of code.
2. Correct Processor CAD/CAA/CSU/CSA operation for operand signs other than 0 or 1.
3. Correct Processor LDB to load only the low-order four digits of the operand into B.
4. Correct Processor SLS shift count; improve mechanization of other shift-left operations.
5. Fix beforeunload event registration for Cardatron and Console devices.
6. Implement "Whippet" mode for Console TTY devices to print at 200 CPS instead of 10 CPS.
7. Expand B220PaperTapePunch translate table to cover all 256 8-bit codes; scroll end of punched data into view.
8. Minor code cleanup in B220PaperTapeReader.
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. 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.
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.
5. Implement Hello World default program for SPO at address 0020.
6. Change keyboard keystroke assignments for B220ConsoleKeyboard.
7. Implement Reset-to-Defaults feature for B220SystemConfig.
8. Implement DOM Element.classList for B220Util class attribute manipulation.
9. Minor typo correction to BALGOL-Generator.bacg.
