+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
+  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.

+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.
+
+## ZDE 1.8 - Lars Nelson 12/3/2022
+
+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

+;   - Use an apparently 'dead' byte in the configuration area as
+;	a configuration flag to allow disabling the 'Auto-Indent'

+;	Overlay for ZMP (Z-Modem Program)
+;
+;	Name	ZMO-WBW.Z80
+;
+;	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.

+;	System-dependent code overlay for ZMODEM
+;
+;
+;
+;    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
+;	MLOAD ZMP.COM=ZMODEM.COM,ZMO-xx01.HEX
+; or
+;	M80 =ZMO-xx01.Z80
+;	RELHEX ZMO-xx01
+;	MLOAD ZMP.COM=ZMODEM.COM,ZMO-xx01.HEX
+;
+;
+;       (Don't use L80 without changing the source for assembly as a
+;         cseg file.)
+;
+;-----------------------------------------------------------------------------
+;
+;
+; 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
+;
+;	call	print
+;	db	'required string',0
+;
+;-----------------------------------------------------------------------------
+;
+;
+;    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.

+; SLICE LABEL - Update Disk Labels
+; Version  December-2024
+;==============================================================================
+;
+; Author: Mark Pruden
+;______________________________________________________________________________
+;
+; Usage:
+;   SLABEL [unit.slice,label] [/?]
+;     ex: SLABEL			Display current list of Labels
+;     	  SLABEL unit.slice=label	Assign a disk Label to the Slice on Unit
+;         SLABEL /?			Display version and usage
+;
+; Operation:
+;   Print and Assign a Disk Label to a Hard Disk Slice.
+;
+; Technical:
+;   On the third sector of "bootable" Disk Slice there is metadata used by RomWBW to know how
+;   to boot the OS found on the slice. This includes a Label for the volume, which is printed
+;   out by RomWBW during the boot process.
+;   Note this label is not associated to any label the OS may assign to the volume.
+;   See loader.asm in each of the O/S directories e.g. /src/CPM22 which describe these sectors
+;
+;   This ony works on slices which have existing media information in the third sector.
+;   There is no capabiity to write this information on demand.
+;
+; known Issues:
+;   - Listing the slabel for all slices can be time consuming, because of the use of the EXT_MEDIA
+;     function call. This function reads the partition table (on each call) to assert (if valid)
+;     the LBA location of the requested slice. Ideally we would only need to read the partition
+;     table once (per device), and work out all the LBA's from this single read.
+;     Note this doesnt omit the fact that the 3 rd sector of each slice wold need to be read regarless.

 # Runtime Memory Layout
 
-![Bank Switched Memory Layout](Graphics/BankSwitchedMemory){ width=100% }
+RomWBW divides the standard 64KB Z80 address space into 2 sections.
+The lower 32KB is the "banked" area.  This is the area that will
+contain any of the 32KB chunks of physical RAM based on which bank is
+currently selected.  The upper 32KB is "fixed".  This area of memory
+is never swapped out and is used to contain software and operating
+systems that must remain in the Z80 address space.
 
+Throughout this document, this mechanism of selecting banks of memory
+into the lower 32K is referred to as memory management.  Achieving
+this functionality requires some type of hardware which is generally
+referred to as the system's Memory Management Unit (MMU).  RomWBW
+supports a variety of MMUs -- but they all perform the same function
+of swapping in/out banks of memory in the lower 32K of CPU address
+space.
+
+Figure 4.1 depicts the memory layout for a system running the CP/M
+operating system.  Applications residing in TPA invoke BDOS services
+of CP/M, BDOS invokes the custom CBIOS APIs, and finally CBIOS
+invokes HBIOS functions as needed by calling into the HBIOS proxy.
+The HBIOS proxy swaps in the HBIOS bank as needed to perform the
+requested function.

 # Disk Layout
 
-RomWBW supports two hard disk layouts: the Classic layout used by 
-RomWBW with 512 directory entries per slice and a Modern layout with 
-1024 directory entries per slice.  These layouts are referred to as
-hd512 and hd1k respectively.
+## Floppy Disk Layout
+
+RomWBVW generally handles floppy disks in the same physical formats
+as MS-DOS.  However, the filesystem will normally be CP/M.  The following
+table lists the floppy disk formats used by RomWBW.  In all cases,
+the sector size is 512 bytes.

+## Hard Disk Layout
+
+RomWBW supports the use of PC MBR hard disk partitioning (see
+<https://en.wikipedia.org/wiki/Disk_partitioning>).  When accessing
+a hard disk device, HBIOS will look for a partition with type id 0x2E
+and will use that partition exclusively for all storage.  If a hard
+disk does not have a valid partition table with a partition of type
+0x2E, the HBIOS will treat the hard disk as dedicated storage and
+will store data starting at the first sector of the disk.
+
+The use of a partition of type 0x2E is preferred for RomWBW and is
+referred to as a "Modern" disk layout.  If there is no RomWBW
+partition on the disk, then the disk is designated as having a
+"Classic" disk layout.
+
+When a disk uses a RomWBW partition (type 0x2E) for storage (Modern 
+layout), the CP/M filesystems on that disk will utilize a format with 
+1,024 directory entries per filesystem.  If there is no RomWBW 
+partition, the CP/M filesystems will have 512 directory entries per 
+filesystem. As a result, the Modern disk layout with a RomWBW partition 
+is also referred to as the "hd1k" layout indicating 1024 directory 
+entries. Similarly, the Classic disk layout (no partition of type 0x2E) 
+is also referred to as the "hd512" layout indicating 512 directory 
+entries.
+
+The layout type of any hard disk is simply dictated by the existence of 
+a RomWBW partition.  This also means that if you add or remove a 
+partition table entry of type 0x2E on existing hard disk media, you will
+lose access to any pre-existing CP/M data on the disk.  If used, 
+partitioning should be done before putting any data on the disk.
 
 WARNING: You **can not** mix the two hard disk layouts on one hard 
 disk device.  You can use different layouts on different hard disk 
 devices in a single system though.
 
-RomWBW determines which of the hard disk layouts to use for a given 
-hard disk device based on whether there is a RomWBW hard disk 
-partition on the disk containing the slices.   If there is no RomWBW 
-partition, then RomWBW will assume the 512 directory entry format for 
-all slices and will assume the slices start at the first sector of 
-the hard disk.  If there is a RomWBW partition on the hard disk 
-device, then RomWBW will assume the 1024 directory entry format for 
-all slices and will assume the slices are located in the defined 
-partition.
+Regardless of whether a disk is Modern or Classic, RomWBW supports
+the concept of CP/M filesystem slices.  In general, CP/M filesystems are
+limited to 8MB.  Since current disk media is dramatically larger than
+this, RomWBW implements a mechanism to put many (up to 256) CP/M
+filesystems on a single disk.  Each such filesystem is called a slice
+referring to the idea that the disk has been sliced into many
+independent CP/M filesystems.  RomWBW allows the disk slices to be
+mapped to the limited (16) drive letters of CP/M.  The mapping can be
+modified on-the-fly on a running system as desired.
 
-RomWBW supports up to 256 CP/M slices (0-255).  Under hd512, the slices
-begin at the start of the hard disk.  Under hd1k, the slices reside
-within partition type 0x2E.
+If the case of a Modern disk layout (with a RomWBW partition), the
+slices are contained within the defined partition area and the number
+of slices is dictated by the size of the partition.  In the case of a
+Classic disk layout (no RomWBW partition), the slices are located at the
+start of the disk (first sector).  In either case, the slices are just

+The best approach is to copy data to the RomWBW partition. To do this, you

+RomWBW disk and partition. An easy way to determine this may be the linux `mount`
+command, which lists the currently mounted partitions. From here you can more easily 
+determine the naming scheme used by your operating system.
+
+Typically disk devices are named something like `/dev/disk9` or `/dev/sdg`, noting above

+
+Partitions are typically named by simply adding a number after the name of the hard disk

+
+Since bs=8MB the `seek=6` skips the first 6 (8MB slices) slices (in the target image)
+and writes the games image to the 7th slice.
+
+#### Example 2 : Copy the entire Combo Image without replacing partition table
+
+In all of the following examples we use `bs=1MB` to defines the block size used
+in other parameters. This is convenient since the combo image reserves 1MB for
+the partition table at the start of the disk.
