Shareware/Speccy/!MZX/!Help

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

MZX - The ARM Unlimited ZX Spectrum Emulator
============================================

!Help file for release 1.10



MZX implements most of the functionality of a 48K Sinclair ZX Spectrum.
It will run in single or multitasking modes on an Acorn RISC OS machine
with at least 1Mb of memory and operating system version 3.00 or later.
It will run in multitasking mode only under RISC OS 3.50.


Using MZX
=========

To load MZX, double click on the !MZX icon. To load MZX with a snapshot
file pre-loaded, double click on the file icon. Note that the file should 
have its type set to SNA (&CEF) if it is a .SNA type snapshot, or to
Z80 (&CEE) if it is a .Z80 type snapshot. To start the emulation when
loaded, click on the MZX icon bar icon. Snapshots can be loaded after
startup by dragging them into the MZX window, or onto the icon bar icon.

More details are given below.
 
Features: 
=========

* Almost complete Z80 instruction set emulation, including all known
  "undocumented" instructions.

* Full colour ZX Spectrum display emulation in a custom screen mode.

* ZX Spectrum keyboard mapping:

All alphanumeric keys are mapped to their Spectrum equivalents.
Shift is mapped to Caps Shift.
Control is mapped to Symbol Shift.
Return is mapped to Enter.
Space is mapped to Break/Space.
Tab is mapped to Extend Mode.
Cursor keys are mapped to Spectrum cursor keys.
Delete is mapped to Spectrum delete.
Full stop, comma, semicolon and double quote are mapped to their Spectrum
equivalents.


A full key map is given in the !Keys file.


Alt is used for "hotkey" controls:

Alt-F1 selects multitasking mode.
Alt-R performs as the 48+ reset button.
Alt-F2 saves a snapshot of the current memory and register contents
as "<Z80$Snap>". (Defaults to the file "SnapShot" in the directory
in which the application resides.)
Alt-Q quits the emulator.
Alt-F5 turns on sound.
Alt-F6 turns off sound.
Alt-F7 and Alt-F8 control volume.
Alt-F9 freezes emulation.
F10 unfreezes emulation.
Alt-F3 decreases speed limiting (when switched on).
Alt-F4 increases speed limiting.

* Multitasking mode.

This is still not perfect, but should be useable on an ARM3 or ARM610
machine. Clicking on the icon bar icon with Select will open a 
multitasking emulation window. Clicking with Adjust will switch to
single tasking mode. (This is not guaranteed to work with all monitor
types.) Alt-F1 returns to the desktop.

* Snapshot file loading

The .SNA file is the most widely accepted snapshot format. MZX will
attempt to load any file of type &CEF which is double-clicked on as
a .SNA format snapshot. In addition, V1.10 will attempt to load any
file of type &CEE as a .Z80 snap, automatically distinguishing between
different versions of .Z80 file. It is not yet possible to load 128K
snapshots. For information on where to get snaps, I suggest that you 
subscribe to the USENET group comp.sys.sinclair.

* Sound support

At present, this will only work on a limited range of machines. I am
still working on a better solution; if you are _really_ desperate for
sound, I suggest you buy either an A300 series, an A400 series, an
A540 or a real Spectrum.

* Acorn Joystick Support

By default the keypad keys 1, 4, 2, 3 and Enter work as if they were a
Kempston joystick. However, if you have a real joystick connected which
provides support for the standard Acorn SWI interface, you can use this as
a virtual Kempston joystick.


Missing Features:
=================

The only significant Spectrum feature which is missing is the FLASH
attribute. This may be added later. In addition, the sound could be
much improved, and the WIMP interface tidied up.

Bugs:
=====

MZX 1.10 will run about 95% of 48K snapshots with few or no problems. The
major known bugs are:

Extended keyboard handling sometimes fails to recognise virtual Shift press
due to hardware differences between Arc and Spectrum.

Multitasking mode sometimes fails to poll properly for unknown reasons;
if some WIMP action fails to work, freezing the emulator will usually
cure the problem.

===========

Improved versions of MZX may still be forthcoming - in addition, if I
have time, I will release other Z80 emulations possibly including SAM
Coupe and CP/M.
                 
Please send me any comments, suggestions, bug reports, cheques, etc.
