The '''CPC Booster (+)''' is an extension card for the CPC specialized on I/O features constructed by [[Antitec]] / [[Dirty Minds]]. It includes components like a very fast serial interface, a music digitizer, a DAC and even a free programmable and useable microcontroller (AVR).

''This list of CPC Booster + features has been copied from its homepage''
* '''ONE SYNCHRONOUS/ASYNCHRONOUS SERIAL PORT:''' Improved serial port with the ability to enable parity check, select the bits of the frame, the stop bits and many more things to control it. The speed is from 4800 baud till 1382400 bauds.
* '''SERIAL PORT BUFFER:''' A 255 bytes buffer added for the UART which can be enabled/disabled by the user. Improves performance of the serial communication.
* '''TWO ANALOG INPUTS:''' Two analog to digital convertors. They are used for stereo or mono 8bit sound sampling. You can select the sampling rate directly from the cpc booster.
* '''TWO PWM CHANNELS:''' They are used as digital to analog convertors through a LOW PASS RC filter. You can play stereo 8bit samples if you connect the board to an amplifier.
* '''5 DIGITAL INPUT/OUTPUTS:''' You can connect anything that supports TTL logic. You can even drive relays or step motors if you know how to make the appropriate connections. You can also make parallel 4 bit communication with another CPC.
* '''512 BYTES EEPROM:''' EEPROM is like RAM but the contents remain intact if you remove power, it doesn't need a battery.
* '''256 BYTES RAM:''' The booster+ has a 256 bytes buffer to be used for temporary storage of values (like storing the registers).
* '''SEVERAL MATHEMATICAL FUNCTIONS:''' At the moment I've only installed multiplication but as soon as I get the time, me and Optimus will write some fast code for division, sin, cos, tan etc.
* '''BIOS UPDATE:''' This is one of the best features of the card. It is possible to make an update of the bios of the microcontroller through the CPC. So, when I release new versions of the bios, you can download them, transfer them to the CPC and make an update of the card in a few seconds!
* '''ROM READ/WRITE:''' The AVR MEGA16 has 16KB of program memory. The bios of the CPC booster uses less than 5 KB so far. So you can use more than 10KB for your own purposes! You can read/write the program memory of the CPC booster but BE CAREFUL when you write because you may accidentally erase the BIOS data!
* '''KEYBOARD SCANNING:''' A function which will make keyboard scanning a lot easier
* '''TCP / IP IMPLEMENTATION:''' This is also a feature I want to add in the future in order to give the CPC users the ability to go online in the internet with their CPC! In this part everyone can contribute, if you have knowledge of how the PPP and TCP/IP works, then contact me.
* '''RS485 NETWORK:''' An RS485 network is installed in the CPC Booster+. With this it's easier than ever to make a super fast network of up to 32 CPCs, forget everything else you've seen so far.
