			REX#/REXCPM both display configuration information to the user when installed, and when in MENU.
			Normally, the display is changed to show the following things:

			2) the current active OPTROM image is shown on the top left.

			Now, REX#/REXCPM displays the status of the VT100 driver. See the image below.

			The status of the VT100 driver is shown on the top right of the MENU screen, just to the left of the active OPTROM indicator.

			There are 2 status items shown - a letter and a number. Here is the decoder:

			D == DeInstalled. The driver is "off"
			S == Safe Mode. The driver is installed and active, and OPTROM access is disabled.
			E == Expert Mode. The driver is installed and active, and OPTROMs are enabled, so be careful!

			0 == SCREEN is set to 0, meaning LCD.
			1 == SCREEN is set to 1, meaning CRT over RS-232 @ 19200 8N1
			2 == SCREEN is set to 2, meaning CRT over BCR Hack @ 57600 8N1

<big>'''Add 80x24 external video to your M100!!!'''</big>

'''Version 2 firmware is now available!''' See the Software section below for details.
Version 2 offers the following improvements:
* First, and most importantly, a serious bug that impacted stability is addressed in Version 2
* Version 2 also includes some new features:
** integrated VT100 video driver support (for M100/T102 only) see --> [[Integrated VT100 driver|REX# / REXCPM Integrated VT100 driver]]
** multi-bank support (for T200 and NEC only)
** CNTL-A to start REX Manager quickly from Menu

= Overview =

<big>'''What is REX#?'''</big>

REX# is an add-on memory card that plugs into the Option ROM socket in a supported laptop, augmenting significantly the amount of memory in the laptop as well as what that memory can be used for.
* REX# provides 1MB of flash memory for the laptop.
* REX# puts bank switched flash memory into the OPTION ROM memory bank (1x32k bank)
* The 1MB flash (32 blocks of 32kB) may then be accessed, one 32k block at a time.
* REXMGR (aka REX Manager) software, loaded into the first 32k block, makes all this memory useful!

<big>'''Main Features and Functions of REX#'''</big>

REX# (via REXMGR software) enables several key capabilities for the Model T user.

* Option ROMs: Applications for Model T laptops were originally distributed as Option ROMs. These ROM images may be loaded into flash blocks, and then quickly switched/activated for use by REX Manager.
* RAM Images: Users can quickly backup or restore the current working RAM of the laptop into one of the 32k flash blocks. This provides a great way to store data, programs, or quickly recover from a cold boot situation.
* Quick Menu: the laptop main menu now has some custom keystrokes that speed up REX# usage.
* Active Optrom display: the main menu also shows the name of the installed option ROM.
* Additional nice things: REX Manager fixes the Y2K date display problem

= Model T variants supported by REX# =

* TRS-80 Model 100
* Tandy 102
* Tandy 200
* NEC PC-8201, 8201A, 8300
* Olivetti M10
* KC-85 (well I don't have one but I'm sure it would work!)

Notes
=====
Model 100:
* In Europe and UK, and probably elsewhere, there are newer versions of M100 that have different boards.
* Model numbers are 26-3801B and 26-3802B.
* REX# does not function correctly in these models, due to the significantly different main ROM.
Olivetti M10 note:
* In order to use REX#, the Olivetti M10 must have it's main ROM updated to be "like the M100".
* The M10 is compatible with standard 27C256 eproms
* Obtain the replacement main ROM image, burn the image and mounting the chip in the main ROM socket.
