Available here is an emulator for the VZ200/300 computers called VZEM (vee zed 'em!) The emulator is under constant
development, however it is still usable and accurately emulates the VZ hardware. 

 

BASIC INFORMATION 

The emulator is written in Borland C++ v3.0 for Dos. The Z80 cpu emulation routines were written by Marat Fayzullin. 

 

STATUS OF EMULATOR 

Currently it emulates: 

     A VZ200/300 with 34k RAM 

     Mode 0 graphics - full VZ character set and colours 

     Mode 1 graphics - 128x64 graphics in 4 colours 

     Video redraw and interrupts at 50hz 

     Sound 

     Virtual joystick using keyboard arrow keys 

     Protected memory writes to ROM and cartridge area 

     VZ keyboard array 

     Loading and Saving of converted tape images 

     Adjustable CPU speed 

     Virtual joystick using PC cursor keys

 

To Do: 

     Joystick 
     Printer 
     Disk Drive 
     Convert to Windows 

...and heaps of other stuff! 

The zip file contains the emulator, VZ rom image, character font and utilities to convert VZ cassette tape audio to the emulator
file format and vice versa. 

The emulator is a DOS program and runs best in a full screen. To get the best sound emulation, exit Windows and run under
plain DOS. 

If your PC is faster than 200mhz, it is likely you will need to slow down the emulation by pressing PGUP. 

A picture of the VZ keyboard is very handy to have around to work out the keyboard mappings - right click the image below
to save to your PC, then you can print it out or have it displayed on your desktop and switch to it when you need it.
