24DEC17 - b0 command in UART monitor stops CPU on BRK instruction
25DEC17 - $DC00 always reads as zeros
26DEC17 - Fix sprite fine horizontal placement problem
26DEC17 - PDM/Sigma-Delta audio output working
26DEC17 - Kickstart looks for file "NTSC", if not present, switches to PAL
26DEC17 - CIA clock speed is always 1MHz, except in C128 2MHz mode.
26DEC17 - Fix CIA clock halving bug
26DEC17 - $D016 smooth scroll in 320H mode fixed
26DEC17 - CIA is 1MHz even in 2MHz mode
26DEC17 - NumLock on PS/2 / USB keyboard is now "joystick lock" (WASD+shift, cursors+space)
27DEC17 - Got rid of single stray pixel by right border
27DEC17 - Make On-screen-keyboard X position variable via $D619
27DEC17 - C= + <- key to toggle matrix mode on C64 keyboards
27DEC17 - On-screen-keyboard again shows key events

29DEC17 - Find hardware errata; No SRQ line on IEC serial port
29DEC17 - Make joystick controlled quick-synthesising debug rig
29DEC17 - Right SID is now on right channel
29DEC17 - $D612 bits 6-7 allow rotation of joystick inputs by 180 degrees
30DEC17 - $D03x can no longer be written over in VIC-II mode
30DEC17 - IEC serial port works, at least partially
30DEC17 - Digital audio outputs reduced volume to prevent amplifier complaining
30DEC17 - Find and fix timer b and ISR reading bugs in CIAs
31DEC17 - Investigate and fix lack of shift register in CIAs for C65 DOS fast mode
31DEC17 - C65 disk drive check succeeds without shift-register status kludge

05JAN18 - dotclock on cartridge port sped up from 4MHz to ~6.5MHz
06JAN18 - dotclock on cartridge port correctly at 8MHz
06JAN18 - 1351 mouse/POT inputs work correctly, and are in MEGA65 VHDL
07JAN18 - 16-colour sprite mode
07JAN18 - Sprite rendering bugs fixed
08JAN18 - Top row of pixels in sprite can now collide
08JAN18 - Sprite:sprite collision detection much more accurate (one Impossible Mission bug remains)
08JAN18 - Sprite Y position corrected
09JAN18 - Ethernet can received (but frames lack CRC!)
09JAN18 - 1581 repaired, and 3.5" test disks prepared
09JAN18 - Ethernet TX phase correction for r1 PCB (but CRC received by nexys still wrong)
09JAN18 - Ethernet TX and RX fully working on both r1 PCB and Nexys4DDR
10JAN18 - Resistor pull-up pack for floppy interface
10JAN18 - Floppy drive reads from real disk
10JAN18 - Worked out how to decode floppy data
