***** yaze version 1.10 of 1998/01/27 *****

Changes since 1.06:

1998-01-27
 * simz80.pl: set the flags correctly for LD A,I/R and
   CPI/CPIR/CPD/CPDR (reported by Sean Young).
 * monitor.c (mountdir): fix fencepost error when setting cp[15],
   as reported by Richard Hirst.

1998-01-25
 * simz80.pl: change direct and indirect references to the RAM()
   macro, because it now evaluates its operand more than once if MMU
   is in use (contributed by Michael Haardt).

 * yaze.c, simz80.h: Make BIOS optional and add MMU initialisation
   (contributed by Michael Haardt).

Changes since 1.05:

1996-04-28
 * cdm.c (getblock): rename index to idx (avoids a warning about
   shadowing index()).
   (main): correct a type in the !USE_GNU_READLINE case.

1996-04-25
 * bios.c (constat, lststat): select() may modify timeval, so
   reinitialise it.
   (readsec,writesec): protect against undefined or unmounted disk.
   (bios): Add BgiiFix.
 * monitor.c (mount): use MAP_FILE flag in mmap() call (linux-ism?).
 * yaze.c (load_cpm): correctly calculate available memory if
   loadadr is specified.
 * simz80.pl (CALLC): rename symbol adr to avoid warning msg.
 * cdm.c (srchdir): ignore cpm-3 byte count.

+Yet Another Z80 Emulator
+========================
+
+Yaze is a Z80 and CP/M emulator designed to run on Unix systems.
+
+The package consists of:
+
+* an instruction set simulator which accurately imitates a real Z80
+  microprocessor,
+
+* a CP/M-2.2 bios written in C which runs on the Unix host but
+  interacts with the simulated Z80,
+
+* a monitor which loads CP/M into the simulated processor's ram and
+  which makes Unix directories or files look like CP/M disks, and
+
+* a separate program (cdm) which creates and manipulates CP/M disk
+  images for use with yaze.
+
+Yaze's "selling points", compared with previously available Z80
+emulators, are:
+
+* It emulates all documented and most undocumented processor-internal
+  instructions and all flag bits (all 8, including the undocumented
+  ones).  A test program is included in the package which exhaustively
+  (well, nearly exhaustively) compares all instructions, for all
+  machine states before and after execution, against the results from
+  a real chip.
+
+* It is independent of the host machine architecture and instruction
+  set.  Written in ANSI standard C it is provided with full source
+  code under the GNU General Public License.
+
+* It supports all CP/M disk geometries in the form of images in Unix
+  files or as read-only disks constructed on-the-fly from the contents
+  of Unix directories.  These disks are indistinguishable from real
+  disks for even the most inquisitive, low-level CP/M programs.  They
+  can be mounted and unmounted at will during emulation.

+This is the first release of yaze since version 1.06 came out about 2
+years ago.
+
+It was prompted by Michael Haardt's work on emulation of non-CP/M
+Z80-Systems.  He contributed the io.c file and the bank switching
+memory logic, which may provide a platform for running MP/M and UZI on 
+the emulator.
