-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 classified 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 running (i.e. Paperboy).
- Corrected frames per second value for 48k and 128k
- Sinclair 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.
- Remapped some Spectrum+ keys.
- Pressing F3 to reset was setting 0xf7 on keyboard
- input port. Problem occurred for snapshots of
- some programs where it was read 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
- completely messed timings.
-25/10/2012 DH - simplified border emulation to be a (manual) partial
- update with bitmap
- Removed legacy fff4 interrupt hack, modern version of
- MAME can handle this just fine
-
-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.
-
-TODO: (the best resource for ZX Spectrum HW informations is the http://www.zxdesign.info/
- blog, a project devored to reverse-engineer the ZX Spectrum in h/w).
-
- 1. No contended memory. The different Spectrum models have different contention timings
- Updated info can be found here: http://scratchpad.wikia.com/wiki/Contended_memory
- Of course, neither "late timing" contention effects are emulated.
-
- 2. Russian models (at least Pentagon and Scorpion) reportedly don't have contended memory.
- Information about screen timings are here: http://www.worldofspectrum.org/rusfaq/
-
- 3. Similarly, contended I/O is not emulated: http://scratchpad.wikia.com/wiki/Contended_IO
-
- 4. Finally, the Floating Bus implementation is incomplete: http://scratchpad.wikia.com/wiki/Floating_bus
- The page hosts a couple of testing programs.
-
- 5. A NTSC model exists: it's not the Timex, but a plain ZX Spectrum made for the Chilean market:
- http://scratchpad.wikia.com/wiki/NTSC_Spectrum
-
- 6. No hi-res colour effects (need contended memory first for accurate timing).
-
- 7. Keyboard autorepeat is broken.
-
- 8. Port decoding on all models needs to be checked and, in case, corrected.
-
- 9. The actual Issue 2/3 effect is a bit more complicated than implemented:
- http://piters.tripod.com/cassport.htm for an explanation/test suite.
-
-10. Tape formats not supported:
- .001, .CSW, .LTP, .PZX, .SPC, .STA, .ITM/.PAN, .TAP(Warajevo), .VOC, .ZXS, .ZXT
-
-11. Disk formats not supported:
- .CPD, .DSK, .FDD, .FDI, .HDF, .IMG, .MDR, .MGT, .SCL, .TRD, .ZXD
-
-12. 128K emulation is not perfect - the 128K machines crash and hang while
- running quite a lot of games.
-
-13. Disk errors occur on some +3 games.
-
-14. EXROM and HOME cartridges are not emulated on Timex machines.
-
-15. The TK90X and TK95 roms output 0 to port #df on start up. The purpose of this port is unknown
- (probably display mode as TS2068) and thus is not emulated.
-
-16. Very detailed infos about the ZX Spectrum +3e can be found at
- http://www.worldofspectrum.org/zxplus3e/
-
-17. The ZX Spectrum is known to support a huge number of peripherals, daisy-chained through its expansion bus.
- In the earlier part of its life cycle, a common configuration consisted of a "docking station"-type
- peripheral providing drive controllers (the disk drives were not part of the packages), a game
- interface (joystick and/or sound chip) and the ZX Printer (which, if present, must terminate the chain).
-
- Later, all-in-one peripherals became more common. The following list is just a little part of the huge
- catalog of peripherals available to the ZX Spectrum; however these peripherals are both the most successful
- and the better documented ones.
-
- Except when noted, technical and usage manuals are available at http://www.worldofspectrum.org/
