PCW came in 4 forms. PCW8256, PCW8512, PCW9256, PCW9512 These systems were nicknamed "Joyce", apparently after a secretary who worked at Amstrad plc. These machines were designed for wordprocessing and other business applications. The computer came with Locoscript (wordprocessor by Locomotive Software Ltd), and CP/M+ (3.1). The original PCW8256 system came with a keyboard, green-screen monitor (which had 2 3" 80 track, double sided disc drives mounted vertically in it), and a dedicated printer. The other systems had different design but shared the same hardware. Since it was primarily designed as a wordprocessor, there were not many games written. Some of the games available: - Head Over Heels - Infocom adventures (Hitchhikers Guide to the Galaxy etc) However, it can use the CP/M OS, there is a large variety of CPM software that will run on it!!!!!!!!!!!!!! Later systems had: - black/white monitor, - dedicated printer was removed, and support for any printer was added - 3" internal drive replaced by a 3.5" drive All the logic for the system, except the FDC was found in a Amstrad designed custom chip. In the original PCW8256, there was no boot-rom. A boot-program was stored in the printer chip, and this was activated when the PCW was first switched on. AFAIK there are no dumps of this program, so I have written my own replacement. The boot-program performs a simple task: Load sector 0, track 0 to &f000 in ram, and execute &f010. From here CP/M is booted, and the appropriate programs can be run. The hardware: - Z80 CPU running at 3.4 MHz - UPD765 FDC - mono display - beep (a fixed Hz tone which can be turned on/off) - 720x256 (PAL) bitmapped display, 720x200 (NTSC) bitmapped display - Amstrad CPC6128 style keyboard If there are special roms for any of the PCW series I would be interested in them so I can implement the driver properly. From comp.sys.amstrad.8bit FAQ: "Amstrad made the following PCW systems : - 1) PCW8256 - 2) PCW8512 - 3) PCW9512 - 4) PCW9512+ - 5) PcW10 - 6) PcW16 1 had 180K drives, 2 had a 180K A drive and a 720K B drive, 3 had only 720K drives. All subsequent models had 3.5" disks using CP/M format at 720K until 6 when it switched to 1.44MB in MS-DOS format. The + of model 4 was that it had a "real" parallel interface so could be sold with an external printer such as the Canon BJ10. The PcW10 wasn't really anything more than 4 in a more modern looking case. The PcW16 is a radical digression who's sole "raison d'etre" was to make a true WYSIWYG product but this meant a change in the screen and processor (to 16MHz) etc. which meant that it could not be kept compatible with the previous models (though documents ARE compatible)" TODO: - Printer hardware emulation (8256 etc) - Parallel port emulation (9512, 9512+, 10) - emulation of serial hardware - emulation of other hardware...? ******************************************************************************/ #include "emu.h" // pcw video hardware #include "includes/pcw.h" #include "cpu/z80/z80.h" #include "machine/i8243.h" #include "machine/upd765.h" // pcw/pcw16 beeper #include "sound/beep.h" #include "machine/ram.h" #include "render.h" #include "softlist.h" #include "speaker.h" #include "pcw.lh" #define LOG_PRN (1U << 1) #define LOG_STROBE (1U << 2) #define LOG_PAR (1U << 3) #define LOG_EXP (1U << 4) #define LOG_MEM (1U << 5) #define LOG_SYS (1U << 6) #define LOG_BANK (1U << 7) #define LOG_RRAM (1U << 8) #define LOG_IRQ (1U << 9) //#define VERBOSE (LOG_SYS) //#define LOG_OUTPUT_FUNC printf #include "logmacro.h" #define LOGPRN(...)
