2. Implement interrupt and device status latching in B5500CentralControl to support better UI display. 3. Implement B5500CardPunch device. 4. Implement preliminary and experimental B5500DummyPrinter device; correct printer I/O initiation in IOUnit. 5. Correct the way that Printer Finished interrupts are handled in IOUnit and CentralControl. 6. Implement Card Load Select in B5500Console and B5500SyllableDebugger. 7. Fix lack of presence-bit detection in return ops for returned values. 8. Redesign B5500CardReader UI to show last two cards read; change method of emptying the input hopper. 9. Set CHECK option and rework SYSTEM/LOG initialization in B5500ColdLoader.html. 10. Centralize system memory cycle time setting; change from 6us to 4us memory cycle time. 11. Increase Processor timeslice to 16ms and rework Processor.schedule() internals for more accurate performance throttling in browsers with poor setTimeout() granularity. 12. Reduce Processor syllable overhead from 2 cycles to 1. 13. Change B5500SPOUnit method of output to "paper" to work better in Google Chrome. 14. Make documentation and debugging enhancements in B5500IOUnit. 15. Release initial test website HTML and Unisys license PDF. 16. Commit Mark XVI DCMCP transcription as of 2013-06-21.
