-# 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
-
-### 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
-  `.EQU` lines for `DEFSERCFG`.
-
-- Combining config settings `AUTOCON` and `VDAEMU_SERKBD` causes issues
-  at the boot loader prompt.  So, all config files have been changed to
-  consistently enable `AUTOCON` and disable `VDAEMU_SERKBD` (`$FF`).  If
-  are want to use `VDAEMU_SERKBD`, you need to set it in your config
-  file as well as disabling AUTOCON.
-  
-### New Features
-
-- RC2014 Front Panel and LCD Screen support.
-
-- Console "takeover" support at Boot Loader prompt by pressing the
-  <space> key twice on an alternate console device.
-
-- Cowgol disk image based on the work of Ladislau Szilagyi.
-
-- TMS video is automatically reset after an OS warm boot which
-  allows OS to recover from applications that reprogram the TMS
-  video display controller.
-
-- Implemented "application" RAM banks that can be discovered bia
-  the HBIOS API.
-
-- Documentation improvements (Mark Pruden), including:
-
-  - Reorganization into multiple directories.
-  - Improved Disk Management section in User Guide.
-  - Overhaul of Disk Catalog.
-  
-- Disk image for Z3PLUS (Mark Pruden).
-
-- `REBOOT` application added (Martin R).  Also, reboot capability
-  added to `CPUSPD` utility.
-
-- `COPYSL` slice copy application (Mark Pruden).
-
-- Improved disk slice management and protection (Mark Pruden).
-
-- Initial NVRAM configuration support (Mark Pruden).
-
-- Enhancements to ASSIGN command to automatically assign drives
-  (Mark Pruden).
-
-
-### New Hardware Support
-
-- NABU w/ RomWBW Option Board.
-
-- EF9345 video display controller driver (Laszlo Szolnoki).
-
-- Duodyne Disk I/O (CP/NET) and Media boards.

-
-- S100 FPGA-based Z80 including console, SD Cards, and RTC.
-

-## ROM Distribution
+# Acquiring RomWBW
 
 The [RomWBW Repository](https://github.com/wwarthen/RomWBW)
 (<https://github.com/wwarthen/RomWBW>) on GitHub is the official
-distribution location for all project source and documentation.
-
-RomWBW is distributed as both source code and pre-built ROM and disk
-images.
-
-The pre-built ROM images distributed with RomWBW are based on the
-default system configurations as determined by the hardware
-provider/designer. The pre-built ROM firmware images are generally
-suitable for most users.
-
-The fully-built distribution releases are available on the [RomWBW
-Releases Page](https://github.com/wwarthen/RomWBW/releases)

-#### Distribution Directory Layout
-
-The RomWBW distribution is a compressed zip archive file organized in a
-set of directories. Each of these directories has its own ReadMe.txt
-file describing the contents in detail. In summary, these directories
-are:
-
-| **Directory** | **Description** |
-|----|----|
-| **Binary** | The final output files of the build process are placed here. Most importantly, the ROM images with the file names ending in “.rom” and disk images ending in .img. |
-| **Doc** | Contains various detailed documentation, both RomWBW specifically as well as the operating systems and applications. |
-| **Source** | Contains the source code files used to build the software and ROM images. |

-# Overview
-
-RomWBW software provides a complete, commercial quality
-implementation of CP/M (and workalike) operating systems and
-applications for modern Z80/180/280 retro-computing hardware systems.
-
-A wide variety of platforms are supported including those
-produced by these developer communities:
-
-* [RetroBrew Computers](https://www.retrobrewcomputers.org)
-  (<https://www.retrobrewcomputers.org>)
-* [RC2014](https://rc2014.co.uk) (<https://rc2014.co.uk>), \

-# Description
-
-## 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, Iomega
-* Serial drivers including UART (16550-like), ASCI, ACIA, SIO
-* Video drivers including TMS9918, SY6545, MOS8563, HD6445
-* Keyboard (PS/2) drivers via VT8242 or PPI interfaces
-* Real time clock drivers including DS1302, BQ4845
-* Support for CP/NET networking using Wiznet, MT011 or Serial
-* Built-in VT-100 terminal emulation support
-
-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 addressable storage on a single device, 
-with up to 128MB accessible at any one time.
-
-## Included Software
-
-Multiple disk images are provided in the distribution. Most disk
-images contain a complete, bootable, ready-to-run implementation of a
-specific operating system. A "combo" disk image contains multiple
-slices, each with a full operating system implementation. If you use
-this disk image, you can easily pick whichever operating system you
-want to boot without changing media.
-
-Some of the included software:
-
-* Operating Systems (CP/M 2.2, ZSDOS, NZ-COM, CP/M 3, ZPM3, Z3PLUS, QPM )
-* Support for other operating systems, p-System, FreeRTOS, and FUZIX.
-* Programming Tools (Z80ASM, Turbo Pascal, Forth, Cowgol)
-* C Compiler's including Aztec-C, and HI-TECH C
-* Microsoft Basic Compiler, and Microsoft Fortran
-* Some games such as Colossal Cave, Zork, etc
-* Wordstar Word processing software
-
-Some of the provided software can be launched directly from the
-ROM firmware itself:
-
-* System Monitor
-* Operating Systems (CP/M 2.2, ZSDOS)
-* ROM BASIC (Nascom BASIC and Tasty BASIC)
-* ROM Forth
-
-A tool is provided that allows you to access a FAT-12/16/32 filesystem.
-The FAT filesystem may be coresident on the same disk media as RomWBW
-slices or on stand-alone media.  This makes exchanging files with modern
-OSes such as Windows, MacOS, and Linux very easy.
-

-
-## ROM Distribution 
-
-The [RomWBW Repository](https://github.com/wwarthen/RomWBW)
-(<https://github.com/wwarthen/RomWBW>) on GitHub is the official
-distribution location for all project source and documentation.
-
-RomWBW is distributed as both source code and pre-built ROM and disk
-images.
-
-The pre-built ROM images distributed with RomWBW are based on
-the default system configurations as determined by the hardware
-provider/designer. The pre-built ROM firmware images are generally
-suitable for most users.
-
-The fully-built distribution releases are available on the
-[RomWBW Releases Page](https://github.com/wwarthen/RomWBW/releases)
-(<https://github.com/wwarthen/RomWBW/releases>) of the repository.
-
-On this page, you will normally see a Development Snapshot as well as
-recent stable releases. Unless you have a specific reason, I suggest you
-stick to the most recent stable release.
-
-The asset named RomWBW-vX.X.X-Package.zip includes all pre-built ROM
-and Disk images as well as full source code. The other assets contain
-only source code and do not have the pre-built ROM or disk images.
-
-#### Distribution Directory Layout
-
-The RomWBW distribution is a compressed zip archive file organized in
-a set of directories. Each of these directories has its own
-ReadMe.txt file describing the contents in detail. In summary, these
-directories are:
-
-| **Directory**            | **Description**                                                                                                                                                    |
-|--------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| **Binary**               | The final output files of the build process are placed here. Most importantly, the ROM images with the file names ending in ".rom" and disk images ending in .img. |
-| **Doc**                  | Contains various detailed documentation, both RomWBW specifically as well as the operating systems and applications.                                               |
-| **Source**               | Contains the source code files used to build the software and ROM images.                                                                                          |
-| **Tools**                | Contains the programs that are used by the build process or that may be useful in setting up your system.                                                          |
-
-`\clearpage`{=latex}
-
-#### Building from Source
-
-It is also very easy to modify and build custom ROM
-images that fully tailor the firmware to your specific preferences.
-All tools required to build custom ROM firmware under Windows are
-included -- no need to install assemblers, etc.  The firmware can also
-be built using Linux or MacOS after confirming a few standard tools
-have been installed.
-
-## Installation & Operation
-
-In general, installation of RomWBW on your platform is very simple. You
-just need to program your ROM with the correct ROM image from the RomWBW
-distribution. Subsequently, you can write disk images on your disk
-drives (IDE disk, CF Card, SD Card, etc.) which then provides even more
-functionality.
-
-Complete instructions for installation and operation of RomWBW are found
-in the $doc_user$. It is also a good idea to review the [Release
-Notes](https://github.com/wwarthen/RomWBW/blob/master/RELEASE_NOTES.md)
-for helpful release-specific information.
-
-## Documentation
-
-There are several documents that form the core of the RomWBW documentation:
-
-* $doc_user$ is the main user guide for RomWBW, it covers the major topics
-  of how to install, manage and use RomWBW, and includes additional guidance
-  to the use of some of the operating systems supported by RomWBW
-
-* $doc_hardware$ contains a description of all the hardware platforms,
-  and devices supported by RomWBW.
-
-* $doc_apps$ is a reference for the ROM-hosted and OS-hosted applications
-  created or customized to enhance the operation of RomWBW.
-
-* $doc_catalog$ is a reference for the contents of the disk images
-  provided with RomWBW, with a description of many of the files on each image
-
-* $doc_sys$ discusses much of the internal design and construction
-  of RomWBW.  It includes a reference for the RomWBW HBIOS API
-  functions.
-
-Each of the operating systems and ROM applications included with RomWBW
-are sophisticated tools in their own right. It is not reasonable to
-fully document their usage. However, you will find complete manuals
-in PDF format in the Doc directory of the distribution.  The intention
-of this documentation is to describe the operation of RomWBW and the ways in
-which it enhances the operation of the included applications and
-operating systems.
-
-Since RomWBW is purely a software product for many different platforms,
-the documentation does **not** cover hardware construction,
-configuration, or troubleshooting -- please see your hardware provider
-for this information.
-

-## Boot Recovery
-
-To assist users when driver faults or misconfiguration causes a boot 
-failure, RomWBW supports a limited recovery capability.  This is 
-achieved by allowing the user to reboot their machine, loading
-a minimal driver set.  Implementation of this feature requires a
-hardware input "BOOT RECOVERY" button to be available and 
-appropriate software configuration to be completed in the HBIOS.
-
-When implemented, holding the "BOOT RECOVERY" button in after a 
-reset or power cycle will cause the normal driver load process to
-be skipped in preference to a minimal set of drivers being loaded.
-
-Typically this would be: Serial communication, RAM disk and parallel
-port IDE interface drivers.
-
-Platforms supporting this option currently are the MBC, Duodyne and
-latter version of the SBC.
- 
-# Configuration
-
-## RomWBW NVRAM Configuration
-
-On systems with RTC devices (that have Non-Volatile RAM), RomWBW supports storing
-some limited configuration option options inside this RAM.
-
-Several configuration options are currently supported; these are known as Switches.
-The following switch ID's are defined, and described in sections below.
-
-| Switch Number | Name         | Description                                   |      
-|---------------|--------------|-----------------------------------------------|

-| 0x01          | Boot Options | ROM or Disk Boot Settings                     |      
-| 0x02          | -n/a-        | -n/a- high order byte of previous switch      |      
-| 0x03          | Auto Boot    | Automatically boot enabled without user input |
-| 0x04 - 0xFE   | -future-     | Future general usage                          |
-| 0xFF          | Status Reset | Get Status or Reset Switches to Default       |     
-
-RomWBW uses bytes located at the start of RTC NVRAM, and includes a Parity check of
-the bytes in NVRAM to check for authenticity before using the configuration.
-
-| NVRAM Byte  | Name         | Description                       |

-to allow the global status of all switches to be determined. The meaning of the switch
-is different for Read (Get Status) and Write (Reset NVRAM)
-
-#### GET (Get Status)
-
-The read Get Status of switches. This returns very specific values from the function call.
