-## RomWBW System Configuration
-
-System Configuration (`SYSCONF`) is a utility that allows system configuration to
-be set, dynamically and stored in NVRAM provided by an RTC chip.
-
-(`SYSCONF`) is both a ROM application ('W' Menu option), and a CP/M utility.
-Noting however the CP/M utility is not included on an disk image, it is found in
-the `Binary/Applications` folder of the RomWBW distribution.
-
-The $doc_user$ has additional information on the use of NVRAM to set your
-system configuration.
-
-### Basic Operation
-
-The application is an interactive application; it does not have a command line syntax.
-Instead commands are executed from within the application in a command line structure.
-
-When you first start the (`SYSCONF`) utility it will display the current switches
-followed by a command listing.
-
-When you first run the (`SYSCONF`) utility the NVRAM will be uninitialised, and can
-be initialised using the (R)eset command, which writes default values to NVRAM.
-
-Updates are done immediately to NVRAM as you enter them, i.e. there is no confirm
-changes step. If you make any incorrect changes, you simply need to enter a new
-command to set the Switch value correctly.
-
-Once a change has been made it is available, however it may not take effect until
-the next system reboot. This is dependent on the Switch itself.
-
-If no NVRAM is provided by your hardware, then running this application will just
-report the missing hardware and exit immediately.
-
-To exit from the application use the (Q)uit command.
-
-### Commands and Syntax
-
-The following are the accepted commands, unless otherwise specified a "Space"
-character is used to delimit parameters in the command.
-
-| Command    | Argument(s)      | Description                                   |

-### Switch Options
-
-#### Auto Boot (AB)
-
-This switch will define if the system will perform auto boot at the RomWBW boot prompt.
-Enabling this will not prevent a user from typing a boot command, so long as the timeout is not
-exceeded. When configured this replaces the (`AUTO_CMD`) variable
-defined in build configuration.
-
-Making changes to auto boot has no affect until the next reboot.

-Partial writes can be completed with 39SF040 chips. Other chips require entire flash to be erased before being written.
-An SBC V2-005 MegaFlash or Z80 MBC required for 1mb flash support. The Updater assumes both chips are same type
-Failure handling has not been tested.
-Timing broadly calibrated on a Z80 SBC-v2

+## SYSCONF (System Configuration)
+
+| SYSCONF             |   |
+| --------------------|---|
+| ROM-based           |Yes|
+| Disk-based          |Yes|
+
+System Configuration (`SYSCONF`) is a utility that allows system configuration to
+be set, dynamically and stored in NVRAM provided by an RTC chip.
+
+(`SYSCONF`) is both a ROM utility ('W' Menu option), and a CP/M application.
+Noting however the CP/M application is not included on an disk image, it is found in
+the `Binary/Applications` folder of the RomWBW distribution.
+
+The section "Setting NVRAM Options" in the $doc_user$ has additional information 
+on the use of NVRAM to set your system configuration.
+
+#### Syntax
+
+The application is an interactive application; it does not have a command line syntax.
+Instead commands are executed from within the application in a command line structure.
+`SYSCONF` command takes no arguments.
+
+| `SYSCONF`
+
+#### Usage
+
+When you first start the (`SYSCONF`) utility it will display the current switches
+followed by a command listing. e.g.
+
+```
+RomWBW System Config Utility
+
+Current Configuration: 
+  [BO] / Boot Options: ROM (App = "H")
+  [AB] / Auto Boot: Disabled
+
+Commands:
+  (P)rint - Display Current settings
+  (S)et {SW} {val}[,{val}[,{val}]]- Set a switch value(s)
+  (R)eset - Init NVRAM to Defaults
+  (H)elp [{SW}] - This help menu, or help on a switch
+  e(X)it - Exit Configuration
+  
+$
+```
+
+When you run (`SYSCONF`) for the first time the NVRAM will be uninitialised, and can
+be initialised using the (R)eset command, which writes default values to NVRAM.
+
+Updates are done immediately to NVRAM as you enter them, i.e. there is no confirm
+changes step. If you make any incorrect changes, you simply need to enter a new
+command to set the Switch value correctly.
+
+Once a change has been made it is available, however it may not take effect until
+the next system reboot. This is dependent on the Switch itself.
+
+If no NVRAM is provided by your hardware, then running this application will just
+report the missing hardware and exit immediately.
+
+To exit from the application use the (Q)uit command.
+
+#### Commands and Syntax
+
+The following are the accepted commands, unless otherwise specified a "Space"
+character is used to delimit parameters in the command.
+
+| Command   | Argument(s)      | Description                                   |
+|-----------|------------------|-----------------------------------------------|
+| (P)rint   | -none-           | Display a list of the current switch value(s) |
+| (S)et     | {SW} {val},...   | Sets an Switch {SW} with specific values(s)   |
+| (R)eset   | -none-           | Reset all setting to default                  |
+| (H)elp    | {SW}             | Provides help on the syntax (values)          |
+| e(X)it    | -none-           | Exit the application                          |
+
+**Where**
+
+| Argument  | Description                                                          |
+|-----------|----------------------------------------------------------------------|
+| {SW}      | Switch ID, typically this is 2 character name to identify the switch |
+| {val},... | a "Comma" separated list of values to set into the switch            |
+
+#### Switch Options
+
+#### Auto Boot (AB)
+
+This switch will define if the system will perform auto boot at the RomWBW boot prompt.
+Enabling this will not prevent a user from typing a boot command, so long as the timeout is not
+exceeded. When configured this replaces the (`AUTO_CMD`) variable
+defined in build configuration.
+
+Making changes to auto boot has no affect until the next reboot.
+
+**Arguments**
+
+| Type     | Arguments  | Description                                            |
+|----------|------------|--------------------------------------------------------|
+| Enable   | 'E'        | Auto Boot. eg. "E,10" will auto boot, after 10 seconds |
+|          | Timout     | Timeout in seconds in the range 0-15, 0 = immediate    |
+| Disabled | 'D'        | No Auto Boot. e.g. "D" will disable autoboot           |
+
+**Examples**

+The above games have been curated from here <https://eblong.com/infocom/>.
+Full game documentation can be found here <https://infodoc.plover.net/>
+
+The game files are a virtual machine code commonly known as Z-Machine, they
+are portable and will run on any machine that has a Z-Machine interpreter.
+
+* All the Z3 games come with the official CP/M interpreter (the `COM` file) 
+  version C last updated by Inforcom on 5th Feb 1985. You can simply run the
+  game by running it from the `COM` program  
+* All latter games Z4, Z5,.. and above, (Marked as * in the listing above)
+  are more sophisticated and require a better interpreter. i.e. VEZZA. 
+
+#### VEZZA (User Area 15)
+
+Vezza is a modern Infocom/Inform/Z-machine text adventure interpreter for 8 bit
+z80 based computers.  What makes it modern is that it is written in hand-crafted
+z80 assembler for maximum speed, and can load not only the classics such as
+Zork 1,2 and 3 but also the later games.
+
+It can run Z1 up to Z8 inform format interactive fiction game files. To run 
+a game with Vezza just type Vezza followed by the game you want to run. e.g.
+
+`VEZZA ZORK0.Z6`
+
+**Note:** One of the bigger constraints is available RAM. An OS such as ZPM
+since it uses banked RAM does have a good amount of available RAM and was 
+used to test these games work.

+
+The versions above are generally from the "Classic Text Adventure
+Masterpieces" released by Activision in (1996) which is the source of
+most modern releases.
+
+The version of Hitchhiker is the one that Douglas Adams postedon his web
+site in the mid-90s. The BBC later posted an illustrated version based
+on the same game file.
+
+The above games have been curated from here <https://eblong.com/infocom/>.
+Full game documentation can be found here <https://infodoc.plover.net/>
+
+The game files are a virtual machine code commonly known as Z-Machine, they
+are portable and will run on any machine that has a Z-Machine interpreter.
+
+All the Z3 games come with the official CP/M interpreter (Version C) last
+updated by Inforcom on 5th Feb 1985
+
+All latter games Z4, Z5,.. and above, are more sophisticated and require
+a better interpreter. i.e. VEZZA.
+
+VEZZA
+
+Vezza is a modern Infocom/Inform/Z-machine text adventure interpreter for
+8 bit z80 based computers.  What makes it modern is that it is written in
+hand-crafted z80 assembler for maximum speed, and can load not only the
+classics such as Zork 1,2 and 3 but also the latter games.
+
+It can run Z1 up to Z8 inform format interactive fiction game files. To run
+a game with Vezza just type Vezza followed by the game you want to run. e.g.
+
+`VEZZA ZORK0.Z6`
+
+**Note:** One of the bigger constraints is available RAM. An OS such as ZPM
+since it uses banked RAM does have a good amount of available RAM and was
+used to test these games work.
+
+This tool is free but the developer accepts your support by letting you
+pay what you think is fair for the tool. If you find this useful consider

+
+The following files are located in user area 15
+
+Available builds (requires CP/M version 3 or compatible system):
+  vezza-b.com  - 80x24 screen, vt52 + Banked CP/M 3
+  vezza-FG.com - 80x30 screen, VT100/ANSI CP/M 3 (tested on Z80-MBC2 & FabGL)
+
+Other builds (Large memory CP/M 2.2, no timed input):
+  vezza-C2.com - 80x24 RunCPM VT100 - no colour
+  vezza-CC.com - 80x24 RunCPM VT100 with 256 ANSI colour codes
+
+Slow builds due to BIOS limitations (extra register presevation, less cache,
+smaller memory build):
+  vezza-AV.com - CP/M 2.2 with VT100 codes plus 16 bit ANSI colour & high
+                 RAM. Works on Agon Light CP/M 2.2
+                 Note: Issues with very high I/O such as screen animations
+  vezza-AX.com - CP/M 2.2 with VT100 codes plus 16 bit ANSI colour, high
+                 RAM & FabGL Italic. Works on Agon Light CP/M 2.2
+                 Note: Issues with very high I/O such as screen animations
+  vezza-RW.com - CP/M 2.2 with VT100 codes plus 16 bit ANSI colour with low
+                 RAM. Tested on RC 2014 SC-126 using TeraTerm
+
+You should (test and) choose one that works on you configuration, and
+ideally copy and rename it as vezza.com, so the Alias COM files can find
+and execute the game.
+
+The above is a subset of available builds. The full repository is available
+at https://gitlab.com/sijnstra1/vezza/
