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/ - ------------------------- -Mass storage controllers ------------------------- - -ZX Interface 1 - up to 8 Microdrives - 1 RS-232 port - 2 ZX Network ports - http://scratchpad.wikia.com/wiki/ZX_Net - -Opus Discovery - up to 2 Disk drives - 1 Centronics port - 1 Joystick port (Kempston) - -DISCiPLE Interface - up to 2 Disk drives - 1 Centronics port - 2 Joystick ports (RH: Sinclair/Kempston, LH: Sinclair) - 2 ZX Network ports - -Plus D Interface - up to 2 Disk drives - 1 Centronics port - -Rotronics Wafadrive - 2 "Stringy" drives - 1 RS-232 port - 1 Centronics port - -Kempston Disc Interface - up to 4 Disk drives (KDOS) - -Beta 128 Disk Interface - up to 4 Disk drives (TR-DOS) - -Philips Disc ROM - ???
