+# RomWBW Release Notes
+
+This file contains information useful to those upgrading to a new
+release of RomWBW.
+
+## All Versions
+
+- **Please** review the "Upgrading" Section of the RomWBW User Guide.
+
+- The RomWBW ROM and the RomWBW disk images are intended to be a
+  matched set.  After upgrading your ROM, it is important to update
+  the OS boot tracks of your disks as well as the RomWBW-specific
+  applications.  This is discussed in the "Upgrading" section of the
+  RomWBW User Guide.
+
+## Version 3.5.1
+
+This is a patch release of v3.5.
+
+### Fixes
+
+- Corrects an issue with the `CPMLDR.SYS` and `ZPMLDR.SYS` files that
+  caused `SYSCOPY` to fail when used with them.
+
+- Added missing `BCLOAD` file to the MS BASIC Compiler disk image.
+  
+### New Features
+
+- Added `SLABEL` application (Mark Pruden).
+
+- Variety of documentation improvements, especially an overhaul of
+  the Hardware Document (Mark Pruden).
+
+## Version 3.5
+
+### Upgrade Notes
+
+- RomWBW is now more strict with respect to hard disk partition
+  tables.  If your hard disk media was created using any of the
+  pre-built disk image files, this will **not** affect you.  Otherwise,
+  you may find you are unable to access slices beyond the first
+  slice.  If so, use `FDISK80` to reset the partition table on the
+  disk.  This will restore normal access to all slices.  **Only** do
+  this if you are having an issue.
+
+- For those building custom ROMs that are overriding `DEFSERCFG`, note 
+  that this setting has been moved to a `#DEFINE` instead of an equate 
+  (`.SET` or `.EQU`).  You will find this `#DEFINE` at the top of all
+  standard config files.  You will need to change your setting to a
+  `#DEFINE` at the top of your config file and remove any `.SET` or

+## Primary Features
+
+By design, RomWBW isolates all of the hardware specific functions in the
+ROM chip itself. The ROM provides a hardware abstraction layer such that
+all of the operating systems and applications on a disk will run on any
+RomWBW-based system. To put it simply, you can take a disk (or CF/SD/USB
+Card) and move it between systems transparently.
+
+Supported hardware features of RomWBW include:
 
 - Z80 Family CPUs including Z80, Z180, and Z280
 - Banked memory services for several banking designs
 - Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip,

 A dynamic disk drive letter assignment mechanism allows mapping
 operating system drive letters to any available disk media.
 Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.)
 support the use of multiple slices (up to 256 per device). Each slice
 contains a complete CP/M filesystem and can be mapped independently to
 any drive letter. This overcomes the inherent size limitations in legacy
-OSes and allows up to 2GB of accessible storage on a single device.

+# ZDE 1.6 (Z-System Display Editor) reconstituted source - MECPARTS 
+11/19/2020
+
+Using the source code of [VDE 2.67]
+(http://www.classiccmp.org/cpmarchives/cpm/Software/WalnutCD/enterprs/cpm/utils/s/vde267sc.lbr)
+as a guide, I've reconstituted the source code for [ZDE 1.6](http://www.classiccmp.org/cpmarchives/cpm/Software/WalnutCD/cpm/editor/zde16.lbr).
+The resulting source code is available from the GitHub repository
+https://github.com/mecparts/zde.
+
+The source has been assembled with:
+
+* Al Hawley's ZMAC: assemble as is.
+* MicroSoft's M80: rename to ZDE16.MAC, un-comment the first two lines
+  and assemble. Use RELHEX to create ZDE16.HEX.
+* ZASM (Cromemco's ASMB): Rename to ZDE16.Z80 and assemble. Use RELHEX
+to create ZDE16.HEX.
+
+Use MLOAD to create ZDE16.COM.
+
+There are still a couple of routines new to ZDE that I haven't figured
+out (yet). But most of them have been sussed out.
+
+## ZDE 1.7 - MECPARTS 11/24/2020
+
+I've fixed the "doesn't preserve timestamps for files larger than a
+single extent under ZSDOS" bug that was present in v1.6. The existing
+ZDENST16.COM program will work with the 1.7 to set the program up for
+your terminal and printer.

+Added routine to save create time stamp under CP/M Plus since 
+CP/M Plus, unlike ZSDOS, has no native ability to set time stamps.
+
+## ZDE 1.9 - Peter Onion 03/27/2025
+
+- Added support for ANSI PgUp, PgDn, Home, & End.
+- Support ANSI F1 key for menu/error escape.

+; This patch file modifies the officially-distributed .COM file
+; for ZDE Ver 1.6 (copyright by Carson Wilson) to:
+;   - Correct a bug which did not preserve create times when
+;	editing files > 1 extent.
+;   - Use an apparently 'dead' byte in the configuration area as
+;	a configuration flag to allow disabling the 'Auto-Indent'
+;	feature which was always 'on' in ZDE1.6.
+;
+; With the second change, you may configure the 'Auto-Indent'
+; feature to be active (as distributed) or disabled (as this patch
+; is configured) by altering the DB at label 'AIDflt' in the
+; second part of this patch file below.
+;
+; Assemble this file to a .HEX file (example uses ZMAC) as:
+;
+;	ZMAC ZDE16A.PAT /H
+;	
+; then overlay the resulting ZDE16.HEX onto ZDE16.COM with MYLOAD
+; (or equivalent) as:

+;
+; The resulting ZDE.COM will be identified as 'ZDE 1.6a' in the

+;
+;	Dated April 14, 2025
+;
+;	Written by -
+;	  Phil Summers, Wayne Warthen
+;
+;	ROMWBW version using HBIOS and https://github.com/mecparts/zmp
+;       version of zmodem
+;
+;	  - All modem/serial i/o is through RomWBW HBIOS.
+;
+;	  - Data bits, stop bits, and parity are determined by HBIOS.
+;           The ZMP settings will have no effect.  Use RomWBW MODE
+;	    command to set serial port config before starting ZMP.
+;
+;	  - Timing delay calculations based on HBIOS reported CPU speed.
+;
+;	  - The pcfg equate determines whether the overlay will
+;           implement port initialization.  Normally, pcfg will be
+;           set to false because ZMP does not allow configuring
+;           many HBIOS speeds (notably the 115200 baud hardwired
+;           into many RCBus systems).  In this case, you must
+;	    configure the modem port using the RomWBW
+;	    MODE command as desired before starting ZMP.
+;
+;	  - The modem port is assigned to an HBIOS character unit.  By
+;	    default, the modem is assigned to HBIOS character unit 1.
+;           An alternate HBIOS character unit may be specified as a
+;	    parameter on the command line as a single number.  For
+;	    example, the following will assign HBIOS port 3 as the
+;	    ZMP modem port:
+;
+;	    ZMP 3
+;
+;         - The original version of ZMP from Ron Murray allows you to
+;           select from 2 logical modem ports.  This overlay ignores
+;	    any attempt to select ports from within ZMP.  The desired
+;	    modem port should be assigned using the command line
+;	    parameter as described above.
+;
+;         - Teraterm users may need to change the ZmodemWinSize value
+;           to 1024 in the teraterm.ini configuration file.

+;    Insert your own code as necessary in this file. Code contained herein
+; has been written in Z80 code for use with M80 or SLR. Assemble as follows:
+;
+;	SLR ZMO-xx01/h

+; or

+;
+;-----------------------------------------------------------------------------
+;
+;
+; Notes on modifying this file:
+;
+;    C requires that functions do not change either index register (IX or IY).
+; If your overlay requires either of these to be changed, ensure they are
+; restored to the original values on return.
+;    Since collecting parameters from C functions can be tricky, only change
+; the parts marked 'Insert your own code here'. Do NOT modify the jump
+; table at the start. Do NOT modify the entry/exit sections of each
+; function. Do NOT pass 'GO'. Do NOT collect $200.
+;    Apart from defining modem functions, this file also defines terminal
+; characteristics. Examples provided are for ADM-3A (with a few of my own
+; additions). Modify to suit your own terminal. An inline print routine
+; is provided for printing strings in the usual way: usage is
+;

+;
+;
+;    Don't forget to set your clock speed at the clkspd variable.
+;
+;
+;    If you find your overlay exceeds the maximum size (currently 0400h),
+; you will have to contact me for another version. If too many people need 
+; to do it, we haven't allowed enough room.
