Subject: ZSIM 2.0 Z80 Simulator uploaded to SIMTEL

I have uploaded to SIMTEL20:

pd1:<msdos.emulators>
ZSIM20.ZIP      Z80 emulator + CP/M 80 bios to RUN CP/M
                            
ZSIM is an (extremely accurate) Z80 emulator (80386/40 -> 8 MHz Z80)
in conjunction with a CP/M 80 bios, i.e. it simulates a Z80 machine, 
that can run CP/M. Together with the original CP/M operating system 
you have a full Z80-CP/M machine.
If you don't have a CP/M system disc at hand, you can use the included 
public domain CP/M compatible operating system SUPERDOS.
ZSIM uses CP/M format discs and a ramdisc.  Supported disc formats 
are CP/M 86 single sided and double sided, but you can install any CP/M 
format PC drives can physically read. So you can use ZSIM to transfer 
data to MS-Dos.  The ramdisc can be saved to the PC harddisc.  
A sample ramdisc containing the SMALL-C compiler is included.
As ZSIM uses an original operating system and CP/M discs it should run 
every CP/M program that does not use special hardware.  All software I 
could test ran.
ZSIM is free for personal use.  Sources of the CP/M bios are included.
NEW IN VERSION 2.0:
* emulation is 20 % faster
* Z80 interrupt handling fully emulated
* a powerful utility to transfer data from CP/M to MS-Dos included
* IOByte support, so you can access your serial port
* the z80 emulation can be linked to your own programs with C interface
