This emulator is written by Tony Friery from UK. The emulator works under Windows 9x / ME / NT 4 / NT 5.

Read the following email written by Tony for the features supported this time:

I have added some new features, notably the keyboard now works correctly, floppy write support, screen reverse etc. And it now seems to run CP/M and BASIC perfectly. There are some glitches in the keyboard handling when a key is held down for a while ( it continues to repeat until you hold it down once more for a while ), and the sound sometimes wraps over itself, but it should still be perfectly usable. Also, you can now load ( binary ) BIN and MZF files directly. BIN files are assumed to load and execute from $0000, MZF files this information is read from the MZF file.

However, supported are:

• Z80 Processor @ 4 MHz
• 32k RAM
• Optional 64k RAM expansion
• Optional Graphics I Card
• Most FDC ( Floppy Controller ) operations ( but see note below ) using CPDREAD DSK format files
• Single channel sound output ( has some issues ) [Requires DirectX]
• Keyboard supported. Keys are in original locations which is annoying sometimes!
  ( Left AltGr is RVS, Left Ctrl is Graph ) - Has AutoRepeat issues :(
• 40 / 80 Column Screen including Screen Inverting
• PPI, PIO and PIT should be fully working, though the 8253 PIT Timer runs slow
• Full RAM profile ( including remapping )
• Can load Binary or MZF images directly without using IPL
  
  

Not yet emulated:

• Optional Graphics II Card
• General Purpose I/O Card
• RS232 Card
• Parallel Printer Card
• FDC "Track" commands ( read / write track ) - This means no formatting possible
• Display VBLANK
• No tape emulation yet

It will soon be possible to read / write tape files using the emulator ( WAV format or MZF format ). Already MZF format is almost tested, so I will include this when it is complete.

About the usage:

On startup, it's running IPL, so attach a floppy ( DSK-image from CPDREAD ) and then tell IPL which floppy to boot.

You'll see some of the screens here to get a short overview of its functions.

Download

You can download now the version 2.97 ( 935 kb ) you saw above. The FONT-file and ROM are included. There are also some DSK-images to use the standard Disk Basic SB-6510 and CP/M 2.2.2.08.

The files:

mz80b.exe ( emulator )
discmgr.exe ( utility; needs borlndmm.dll and cc3250mt.dll )
roms/mzbasic.dsk ( CPDREAD disk image of SB-6510 and some programs )
roms/ipl.bin ( MZ-80B IPL ROM )
roms/z80bcpm.dsk ( CPDREAD disk image, CP/M 2.2.2.08 and several files for it )
readme.txt

Unzip all files into the directories specified in the ZIP-file. Ready... enjoy it.
