2. Change name of CentralCentrol bit() method to bitTest(). 3. Correct length of data sent to printer by IOUnit if I/O descriptor has a zero length. 4. Implement Processor.isP1 property to optimize testing for Processor 1 vs 2. 5. Implement ability to delete the IndexedDB database for the disk subsystem in ColdLoader. 6. Implement "purist" mode in B5500Console to suppress display of emulator's extra annunciators. 7. Correct behavior of Input Request and Ready controls in SPOUnit.
