a29f2cac5d Commit retro-220 emulator version 0.07:
1. Implement centralized pop-up window opening mechanism to enforce a delay between pop-up opens. This is to satisfy new restrictions on multiple pop-ups imposed by the Apple Safari 11.0 browser.
2. Correct Reload-Lockout behavior and format band 6 initialization in B220CardatronInput.
3. Correct translation of sign digits and skip-to-channel behavior in B220CardatronOutput.
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.

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.

6c51a5803b Commit 220 emulator version 0.4:
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.
