2. Fully implement Double Precision Add/Subtract (DLA/DLS), Multiply (DLM), and Divide (DLD) syllables. 3. Replace standard setTimeout() by redesigned setCallback() mechanism throughout the emulator for scheduling timing delays and other callbacks on the Javascript thread. Delete obsolete setImmediate() mechanism. 4. Replace "new Date().getTime()" by "performance.now()" calls for greater timer precision. 5. Minor tweaks to Single Precision arithmetic operators. 6. Replace Javascript postfix operators by prefix operators wherever feasible (e.g., x++ becomes ++x). 8. Attempt to correct character translation and keyboard filtering in DatacomUnit for CANDE. 9. Minor changes to button colors and illumination behavior for I/O devices and Console. 10. Suppress I/O device classes in B5500SyllableDebugger by default (uncomment in source to enable). . Drop support for webkitIndexedDB and mozIndexedDB (for now). . Configure four tape drives (MTA-MTD) by default.
