JOYCE

JOYCE emulates the Amstrad PCW on Unix, Windows and Mac OS X. Since it's written using SDL, it shouldn't be too hard to port it to other platforms such as MacOS Classic or BeOS.

JOYCE incorporates ANNE, which emulates the PcW16.

Update History


2025年08月09日: JOYCE v2.5.4 (development) released. Corrected default palette on built-in GSX driver to match GSX documentation.

2021年08月05日: JOYCE v2.2.15 (stable) released: Fixes handling of DSK files with unformatted tracks.

2021年01月07日: JOYCE v2.2.14 (stable) released: Fixes autodetection of extended DSK files, display artefacts when colours are changed while video is disabled, and Rosanne checksum detection when the ROM is patched.

2019年06月29日: JOYCE v2.2.13 (stable) released: fixes compilation on recent Unix distributions. Since this only applies to Linux source builds I haven't done a new Windows pack.

2017年07月07日: JOYCE v2.2.12 (stable) released: the default keyboard mapping for the # and \ keys under Windows has been corrected.

2017年02月12日: JOYCE v2.2.11 (stable) released: added a feature allowing up to 13 emulated hard drives in CP/M (rather than 5-6 as in previous versions). Also corrected the build process so LyX is not required.

2016年04月16日: JOYCE v2.2.10 (stable) released: compilation fixes for recent GCC versions. Since these only apply to Linux source builds I haven't done a new Windows pack.

2016年04月16日: JOYCE v2.2.9 (stable) released. This adds emulation of the Electric Studio light pen.

2014年10月08日: JOYCE v2.2.7 (stable) released. This contains code to guard against the possibility of a malicious CP/M program overwriting or deleting important files on the host computer or crashing JOYCE. If you use JOYCE / ANNE to run CP/M programs downloaded from the Internet, I recommend that you upgrade to this version.

2012年10月24日: JOYCE v2.2.5 (stable) released, with compilation fixes for the latest version of libpng, and a fix for a crash in the native VGA driver.

2010年11月03日: JOYCE v2.2.4 (stable) released. Improvements to keyboard emulation; some compiler warnings removed, and an updated SDL.DLL included with the Windows version.

2010年06月09日: JOYCE v2.2.3 (stable) released. This has a further correction to the configuration script.

2009年11月08日: JOYCE v2.2.2 (stable) released. This corrects some compilation issues on recent Linux systems.

2007年12月28日: JOYCE v2.2.0 (stable) released. Apart from minor code cleanups, this is unchanged from the last development version, 2.1.11.

2007年02月04日: JOYCE v2.1.11 (development) released. A bug in the Z80 emulation which caused Starglider to hang has been fixed.

2006年04月23日: JOYCE v2.1.10 (development) released. A longstanding bug which prevented the PCKEY utility working has been fixed.

2006年01月23日: JOYCE v2.1.9 (development) released. This includes a bugfix to the new folder support in 2.1.8, and some changes to allow compilation on Mac OS X.

2005年12月17日: JOYCE v2.1.8 (development) released. This allows folders on the host PC to be used as disc images, without the need for any changes to the software on the PCW.

2005年04月24日: JOYCE v2.1.7 (development) released. The native GSX and Logo drivers (which went missing in JOYCE 2.0.0) have been brought back.

2005年01月31日: JOYCE v2.1.6 (development) released. This version improves support for some PCW games and disc protection schemes. The Windows version now works if there are no printers set up.
2004年02月21日: JOYCE v2.1.5 (development) released. This version adds support for joystick emulation using the host PC's joystick(s).
2004年01月26日: JOYCE v2.1.4 (development) released. Support for my proposed extension to the DSK format has been added; this allows the emulated PcW16 to load CP/M.
2003年12月20日: JOYCE v2.1.3 (development) released. Various bug fixes in the PcW16 acceleration code.
2003年12月20日: JOYCE v2.1.2 (development) released. The bug fixed last year in 2.0.2 is now fixed in the development version as well. This version also includes acceleration code in the PcW16 emulator, allowing slow operations such as the memory test to be skipped.

PCW Miscellany

These are here because I can't think of anywhere else among my pages to put them.

PCW hardware information

This is included in the JOYCE package, but it's here in case you want it as a separate download: PCW hardware information.

The PCW Keyboard

Keyboard layout and wire protocol.

Gem Drive / Flash Drive hardware information

JOYCE does not emulate the Cirtech Gem hard drive or Flash Drive; its own emulated hard drive does not match any real-world hardware. But I've documented the real hardware: Gem Drive and Flash Drive.

(See also the Gem Drive installation instructions below)

PCW television output

This is a circuit diagram for a PCW-to-television converter, allowing a PCW screen to be displayed on one or more television sets. I redrew it from the original, published in the Crawley PCW Club magazine.

PCW / PC Hybrid

[swift286.jpg, 91Kb]

This advertisement is for a "Swift-286-PCW", a hybrid between a 286 PC and a PCW. Apparently only fourteen of these were ever sold, so the chances of one still existing must be pretty slim.

Though I've not seen one, I'd guess that the PCW compatible video card was a monochrome card (I'd guess MDA or Hercules; the ATI Small Wonder would also be a possibility). The PCW video system has a command ('float video' - OUT 0xF8, 8) which stops the PCW video controller trying to drive the monitor. The monitor signals are present on the PCW expansion port (pin 44 for SYNC, 46 for VIDEO) so once the PCW video controller has been disabled, the PC video card can drive the monitor using them.

My thanks to David Rathbone, who owned Micro Surgeons, for information on this system.
