+Interrupts:
+
+Changes:
+
+29/1/2000 KT - Implemented initial +3 emulation.
+30/1/2000 KT - Improved input port decoding for reading and therefore
+ correct keyboard handling for Spectrum and +3.
+31/1/2000 KT - Implemented buzzer sound for Spectrum and +3.
+ Implementation copied from Paul Daniel's Jupiter driver.
+ Fixed screen display problems with dirty chars.
+ Added support to load .Z80 snapshots. 48k support so far.
+13/2/2000 KT - Added Interface II, Kempston, Fuller and Mikrogen
+ joystick support.
+17/2/2000 DJR - Added full key descriptions and Spectrum+ keys.
+ Fixed Spectrum +3 keyboard problems.
+17/2/2000 KT - Added tape loading from WAV/Changed from DAC to generic
+ speaker code.
+18/2/2000 KT - Added tape saving to WAV.
+27/2/2000 KT - Took DJR's changes and added my changes.
+27/2/2000 KT - Added disk image support to Spectrum +3 driver.
+27/2/2000 KT - Added joystick I/O code to the Spectrum +3 I/O handler.
+14/3/2000 DJR - Tape handling dipswitch.
+26/3/2000 DJR - Snapshot files are now classifed as snapshots not
+ cartridges.
+04/4/2000 DJR - Spectrum 128 / +2 Support.
+13/4/2000 DJR - +4 Support (unofficial 48K hack).
+13/4/2000 DJR - +2a Support (rom also used in +3 models).
+13/4/2000 DJR - TK90X, TK95 and Inves support (48K clones).
+21/4/2000 DJR - TS2068 and TC2048 support (TC2048 Supports extra video
+ modes but doesn't have bank switching or sound chip).
+09/5/2000 DJR - Spectrum +2 (France, Spain), +3 (Spain).
+17/5/2000 DJR - Dipswitch to enable/disable disk drives on +3 and clones.
+27/6/2000 DJR - Changed 128K/+3 port decoding (sound now works in Zub 128K).
+06/8/2000 DJR - Fixed +3 Floppy support
+10/2/2001 KT - Re-arranged code and split into each model emulated.
+ Code is split into 48k, 128k, +3, tc2048 and ts2048
+ segments. 128k uses some of the functions in 48k, +3
+ uses some functions in 128, and tc2048/ts2048 use some
+ of the functions in 48k. The code has been arranged so
+ these functions come in some kind of "override" order,
+ read functions changed to use READ8_HANDLER and write
+ functions changed to use WRITE8_HANDLER.
+ Added Scorpion256 preliminary.
+18/6/2001 DJR - Added support for Interface 2 cartridges.
+xx/xx/2001 KS - TS-2068 sound fixed.
+ Added support for DOCK cartridges for TS-2068.
+ Added Spectrum 48k Psycho modified rom driver.
+ Added UK-2086 driver.
+23/12/2001 KS - 48k machines are now able to run code in screen memory.
+ Programs which keep their code in screen memory
+ like monitors, tape copiers, decrunchers, etc.
+ works now.
+ Fixed problem with interrupt vector set to 0xffff (much
+ more 128k games works now).
+ A useful used trick on the Spectrum is to set
+ interrupt vector to 0xffff (using the table
+ which contain 0xff's) and put a byte 0x18 hex,
+ the opcode for JR, at this address. The first
+ byte of the ROM is a 0xf3 (DI), so the JR will
+ jump to 0xfff4, where a long JP to the actual
+ interrupt routine is put. Due to unideal
+ bankswitching in MAME this JP were to 0001 what
+ causes Spectrum to reset. Fixing this problem
+ made much more software runing (i.e. Paperboy).
+ Corrected frames per second value for 48k and 128k
+ Sincalir machines.
+ There are 50.08 frames per second for Spectrum
+ 48k what gives 69888 cycles for each frame and
+ 50.021 for Spectrum 128/+2/+2A/+3 what gives
+ 70908 cycles for each frame.
+ Remaped some Spectrum+ keys.
+ Presing F3 to reset was seting 0xf7 on keyboard
+ input port. Problem occurred for snapshots of
+ some programms where it was readed as pressing
+ key 4 (which is exit in Tapecopy by R. Dannhoefer
+ for example).
+ Added support to load .SP snapshots.
+ Added .BLK tape images support.
+ .BLK files are identical to .TAP ones, extension
+ is an only difference.
+08/03/2002 KS - #FF port emulation added.
+ Arkanoid works now, but is not playable due to
+ completly messed timings.
+
+Initialisation values used when determining which model is being emulated:
+ 48K Spectrum doesn't use either port.
+ 128K/+2 Bank switches with port 7ffd only.
+ +3/+2a Bank switches with both ports.
+
+Notes:
+ 1. No contented memory.
+ 2. No hi-res colour effects (need contended memory first for accurate timing).
+ 3. Multiface 1 and Interface 1 not supported.
+ 4. Horace and the Spiders cartridge doesn't run properly.
+ 5. Tape images not supported:
+ .TZX, .SPC, .ITM, .PAN, .TAP(Warajevo), .VOC, .ZXS.
+ 6. Snapshot images not supported:
+ .ACH, .PRG, .RAW, .SEM, .SIT, .SNX, .ZX, .ZXS, .ZX82.
+ 7. 128K emulation is not perfect - the 128K machines crash and hang while
+ running quite a lot of games.
+ 8. Disk errors occur on some +3 games.
+ 9. Video hardware of all machines is timed incorrectly.
+10. EXROM and HOME cartridges are not emulated.
+11. The TK90X and TK95 roms output 0 to port #df on start up.
+12. The purpose of this port is unknown (probably display mode as TS2068) and
+ thus is not emulated.
+
