Tweaks to keyboard (no longer loses keystrokes, auto-repeat is disabled unless REPT (Alt key) is held down. Fixed 40 cycle sync interrupt (must wait for display to halt as well.) SSV.22 behaves sanely with large numbers of characters displayed now. Slowed TTY interface down, MAZE now loads reliably from ITS.

Tweaks for interrupt handling; added one instruction delay after ION before enabling interrupts, interrupts are now clocked on the leading edge of the processor Fetch cycle rather than on every clock cycle.

Implemented most of the PDS-4 display hardware enhancements (including BLINK, which is very important.) Implemented SBL and SBR, multiple indirects, and fixed decdoding of ACT 2 instructions. Rewired interrupt status bits (arbitrarily rearranged on the PDS-4). SSV4 now mostly seems to work, keyboard still non-functional.
