INTRODUCTION
============

Thank you for choosing this new ACME hardware for your good old CPC!
The MiniBooster is a COM board powered by a 14.74MHz ATmega MPU. 
It allow to exchange data with a PC using a fast USB or Bluetooth connection.
Its exclusive SPI Master bus will allow you to expand the CPC capabilities...

|_____________||_____________| --(5)

1. MOD/EXT switch            = Chose between the two COM connectors	
2. EXTernal pins connector   = USB pins cable or SPI extra devices
3. MODule slot connector     = Plug the optional bluetooth module here
4. RI/RO jumper + CLK pin    = Reset signal... Don’t move or remove it!
5. Expansion port connector  = To MotherX4 or CPC using a ribbon cable


DEVICES PINOUT
==============

1. USB cable

Green wire -> RxD pin
White wire -> TxD pin	
Black wire -> GND pin

Set “EXT” , then plug it to your PC.
Never connect the red wire!

2. Bluetooth module

TxD <-> RxD
RxD <-> TxD
GND <-> GND
VCC <-> +5V

Set “MOD” , then plug it to the slot.
The default pairing code is "1234".


FIRST BASIC TEST
================

PRINT INP(&FF00)  display  170  (device type = CPC Booster)
PRINT INP(&FF01)  display  238  (device model = MiniBooster)
PRINT INP(&FF04)  display    7  (device speed = 115200bps)


BAUD RATES VALUES
=================
 
191 =  4800bps    47 = 19200bps    15 =  57600bps
 95 =  9600bps    31 = 28800bps     7 = 115200bps
 63 = 14400bps    23 = 38400bps     3 = 230400bps


MINIBOOSTER UTILITIES
=====================

1. Bluetooth Init
If your Bluetooth module is not detected or if you don’t chose to get it from ACME, you can initialize it yourself. Use 4-pins HC-06 module only!
The process take some seconds for detecting the current baud rate, setting the new speed to 115200bps and the device name to “CPC MiniBooster”.

RUN”INIT115K”

2. Firmware Backup
Before updating your MiniBooster firmware for adding new features, you may backup the current version on this floppy disc. Leave it unprotected.
The process can take some minutes for reading the current firmware and saving it. The file will be named “BACKUP.BIN” and the previous renamed “.BAK”.

RUN”BACKUP”

3. Firmware Update
New features are work in progress for your MiniBooster. They may require to update the firmware. 
If no floppy disc is provided, you will have to copy the “UPDATE.BIN” file on this one.
The process can take some minutes. If the CPC fail to update the firmware then no worry, just start it again!

RUN”UPDATE”
