1. Alter method of writing disk sectors to IndexedDB, to avoid dragging along the entire 16KB IO Unit buffer area and unintentionally inflating host disk usage by 30-60X (ouch). This was causing Quota Exceeded errors in recent versions of Firefox. 2. Add onabort traps in B5500DiskUnit to catch QuotaExceeded errors. 3. Modify delay-deviation adjustment mechanism in B5500SetCallback to avoid oscillating between positive and negative cumulative deviations. 4. Correct tape reel angular motion in B5500MagTapeDrive, especially during reverse tape movement. 5. Fix bug with reporting memory parity error during tape I/O, should that ever occur. 6. Reset CPA Algol Glyphs option in default system configuration template. 7. Allow tools/B5500LibMaintDecoder to examine an entire .bcd tape image file instead of just the first 64KB. 8. Add USE SAVEPBT to default options in tools/COLDSTART-XIII deck. 9. Eliminate extraneous "schema update successful" alert when altering a disk subsystem configuration. 10. Commit minor corrections to source/B65ESPOL/SOURCE.alg_m from Richard Fehlinger.
