Added new commands:
...
"draw invisible vectors" - displays non-drawing beam motion in red.
"hide invisible vectors" - returns to normal rendring mode
"step display" - runs until the next display rendering command completes, refreshes the display to allow easier debugging of display programs.
Console input buffer is now cleared after a break operation.

Fixes for disassembly of uncached instructions; enhancements of display instruction disassembly. More refactoring of display processor code.

Updates to readme.txt. Updated clock speed for PDS-4 emulation. Fixed issue on non-windows platforms for high-dpi calls.

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.

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.

Implemented decoding of PDS-4 display instructions, updated LVM decoding and execution (completely different from PDS-1). Execution of new PDS-4 display instructions not yet implemented; awaiting the discovery of code that uses them.
...
Tweaked color of point-plotted and vectors that resolve to a single point, brighter and slightly different shade of green for effect.

Initial swipe at refactoring display processor to allow separate PDS-1 and PDS-4 variants.

More PDS-4 work; most of the PDS-4 main processor instructions are implemented though not thoroughly tested (no software that has been unearthed of uses most of them). The byte-wise instructions have not been tackled yet.
...
MIT DADR behavior is corrected, now acts as a toggle. Single point plotting is now brighter than vector drawing for emphasis. Minor correction to disassembly of HLT instructions. Move config options to a new Configuration class, will someday be more sophisticated.
