    CREDIT CARD COMPUTER REV G VER 0.43 SPEC SHEET        (C) MVS 2000




DESCRIPTION
-----------

The MVS Credit Card Computers (CCC1/2) use MV1200/MV8515 chips with
advanced RISC architecture and have significant advantages over other
controllers.  These include lower cost, higher performance, and easier
programming.  The CCC runs over 10 times faster than 8051, PIC, or Z80
types with the same crystal because of longer instruction word (16-bit) and
because the clock is not divided internally.  It has built-in BASIC like
"Stamp" circuit board modules but with more memory, more I/O, and a PC bus.

MVS PLUG-N-GO means the card can be plugged into a PC for testing and works
right away.  The PC is used for power and download.  No costly development
kit, cables, or power supply to buy.  Single-wire Multi-drop Long distance
Network (SMPLNET) is available allowing many modules to talk on one wire
and stack efficiently.  A standard PC RS232 port can also share the wire.

Features include built-in non-volatile memory, enhanced BASIC instructions,
and ISA type bus for attaching PC adapter cards (modem, ADC, video, PCMCIA,
Triac, etc.).  I/O consists of serial/parallel ports and high-speed Analog
Converters.  The chip is socketed so it functions as a programmer in
addition to being a controller.  CCC1a is available at the same price with
a 20mhz CPU and SRAM instead of EE for high-speed apps (audio, video, etc).

Three models are available:

 CCC1: MV1200,256k EE,8bit 4ch ADC,3 serial lines,25 parallel-ISA/104 bus
 CCC2: MV8515,4meg Flash,12bit 4ch ADC,5 serial,41 parallel-ISA/104 bus
 CCC3: Dual CPU version is CCC1 with 1200 but also includes CCC2 type 8515
 
Software and hardware details can be found in the appropriate manual for
the chip used.  For high end applications MVS has a line of PC compatible
8088 and 386 Single Board Computers with up to 64 Mbyte memory capacity.

The CCC1 has a 4 channel 8 bit 50khz ADC and the CCC2 has 12 bits at
150khz.  0-5v Digital to Analog Converter bits can be implemented using a
simple RC network.  Variable motor control is possible using a high current
driver instead of the RC network.  In many cases nothing more than a power
transistor will work.  These bits can also control standard PWM type
electro-mechanical servos via direct connection.

To test plug the CCC into COM1 and type "mvterm 3f8 c /3" at the DOS
prompt.  Next hit "alt-r" to reset the card.  The LED blinks and the POST
(Power-On-Self-Test) message is sent at 9600 baud.  CCC power is provided
by serial handshake lines (4,7).  An extension cable helps if access to the
PCs rear is inconvenient.  Use COM2 (mvterm 2f8) if COM1 is occupied.

WARRANTY
--------

MVS will repair free of charge products suffering from manufacturing
defects for a period of 5 years after shipping.  This will be done only if
it has been determined by MVS that the product has not been misused
(improper voltages, physical alteration, etc.).  Otherwise a minimum
service charge is required.  In either case it is necessary to contact the
company for a Returned Merchandise Authorization (RMA) number before
shipping the unit.
