1. Split operator Control Panel from B5500Console and make it a small, separate window. 2. Implement emulator home page in what remains of B5500Console page, with Start buttons for emulator. 3. Implement improvements to setCallback() mechanism, copied from Datatron 205 project. 4. Increase scrollback for SPO and Datacom windows from 1500 to 5000 lines. 5. Correct application of green-bar styling in B5500LinePrinter (apparent in Chrome). 6. Improve initial positioning of Magnetic Tape unit windows; add "B" to mag tape reel image. 7. Minor optimizations to bit-field isolate/insert routines in CentralControl. 8. Miscellaneous enhancements to UI appearance. 9. Minor changes to hosting website pages.
