paul.kimpel@digm.com 2dadec8b8b Release emulator version 0.17:
1. Enable (finally!) functioning of P2, the second processor, in CentralControl and Processor.
2. Fix bugs in Character Mode syllables FAD, FSU: initial compare of operands was alphanumeric instead of numeric.
3. Fix bugs in Character Mode syllables TRN, TRZ, TBN: non-boundary destination words were not being fetched into the B register.
4. Enable configuration of additional tape drives (up to the maximum of 16).
5. Implement new flip-flop latching mechanism in CentralControl for use by B5500Console.
6. Optimize clearing of interrupts in Central Control.
7. Implement preliminary mechanism to allow P2 to be added to the configuration temporarily without altering B5500SystemConfiguration.js.
8. Implement new average slack and delay algorithms in Processor.schedule().
9. Optimize some Character Mode syllables by substituting local variables for "this" properties.
10. Fix bugs in Processor single-precision divide syllables leaving the stack in an incorrect state after a divide by zero in Control State.
11. Further minor tweaks to performance throttling.
12. Optimize references to this.cc in Processor.run().
13. Minor improvements to B5500MagTapeDrive: eliminate oscillation at load point, improve timing of rewind operations.
14. Implement build-release.cmd script to generate emulator release archive files.
15. Commit initial Mark-XVI TSSINT transcription from Fausto Saporito.
