2. Inhibit peripheral device windows from being closed while emulator is active. 3. Shut down peripheral devices and close their windows as part of cc.powerOff(). 4. Add shut-down code to peripheral drivers. 5. Ensure SPO is ready in cc.load(). 6. Enable emulator version display on B5500Console. 7. Clear DummyPrinter window when it is double-clicked (finally got this working). 8. Fix problem with "/" not accepted by SPO input in Google Chrome. 9. Commit ESPOL binary card loader image. 10. Fix problem with intensity levels in B5500Console NORMAL/CONTROL lights. 11. Attempt to enable emulator and utilities for Safari-style IndexedDB.
