RE: Arrrrrrrgggg!
Some info to stimulate the sharp brains out there?
Not requiring a single hardware design or form factor provides system designers with the flexibility needed to design the TINI chipset into custom products. But without a concrete and commercially available reference implementation of TINI hardware, each new design would have to begin with the rather lengthy process of designing and debugging new hardware. The DS-TINI-1 has been developed to solve this problem. It allows both hardware and software designers to begin prototyping and development work without a large up front investment of either money or time.
The DS-TINI-1 serves the following purposes:
Reference implementation—All of the details of its design are public. Hardware developers are free to use information gleaned from the DS-TINI-1 when designing the chipset into their own TINI-based systems.
Development tool—It provides easy access to much of the platforms's I/O capability allowing designers to quickly interface custom external hardware and develop their applications. It has also been used internally by the TINI engineering team to develop and test the runtime environment.
System Component—The DS-TINI-1 is a fully specified design. It has been heavily tested and functionally characterized over voltage and temperature and is therefore well suited for use as a core component for deployment in commercial and industrial embedded network applications.
The DS-TINI-1 is a compact (31.8 mm x 102.9 mm) 72-pin SIMM board. It is an Ethernet-ready hardware implementation and supports all of the following features:
Hosts the TINI runtime environment in a validated hardware design
10 Base-T Ethernet for networking
Extensive I/O capabilities of the DS80C390 microcontroller exposed through Java™ APIs
Dual serial ports
Dual 1-Wire® net interfaces
Dual CAN (Controller Area Network) controllers
2-wire synchronous serial bus
General-purpose digital I/O
Easy system expansion using parallel bus interface
Real-time clock for time stamping
Flash ROM for storage and execution of runtime environment
512K/1 Mbyte nonvolitile SRAM provides fast, unlimited write operations and persistent data storage
Level translator provides RS232 voltages
Wide operating temperature range, -20°C to +70°C
Requires only a single +5V power supply

Chris and all,
I think there is little chance of using a standard interface. The way the
Mark IV was designed, there is no way to stop the scan once it has
started. Everyone seems to be ignoring this.
THERE IS NO WAY TO STOP THE SCAN ONCE IT HAS STARTED
THERE IS NO WAY TO STOP THE SCAN ONCE IT HAS STARTED
THERE IS NO WAY TO STOP THE SCAN ONCE IT HAS STARTED
THERE IS NO WAY TO STOP THE SCAN ONCE IT HAS STARTED

All the standard interfaces use handshaking. This has to be ingored and
the software written in a way that the 16 MByte block is captured at the
rate it arrives. The ECP contains a FIFO so this may be possible.
