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.
