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.
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/
