Document Information --------------------- Author: David Goodwin Document Version: 1.0 Revision Date: 16 October 2008 Changelog: 16-OCT-2008 Initial version 1. Power Requirements --------------------- The board was 2A at 12V AC (yes, 12 Volts alternating current). The original PSUs are marked as (With ASCII drawings of the pictures) _______________________________ eTe PRI: 230V/240V 50Hz SEC: 12V AC 2A _---_---_---_ TYPE: PAC 12-2 AUST. APP. NO.N13882 CAUTION: FOR INDOOR USE ONLY +-----+ |+---+| ( )( ) || || ( () )] |+---+| ( )( ) +-----+ EEEE TTTT EEEELECTRONIC & TTTTRANSFORMER EEEE TTTT EEEE EEEEngineering LTD. EEEE _______________________________ Where the dashes on the SEC line indicate a straight line on the top and a dashed line under it. Under the "CAUTION" line is a box with a box inside it. Next to this double box symbol is two linked circles. The Right side of the Right one has a little box on it. At the bottom of the label is "Electronic & Transofrmer Engineering Ltd." with the E, T and E being large caps and the rest being small caps. The back of the PSU says: _______________________________ 4795 Manufactured in TTTTT New Zealand by EEE T EEE E.T.E. LTD. EEE T EEE _______________________________ The PSUs two output wires just connect straight up to the green connector P6 in the top right corner of the board. 2. Hardware --------------------- CPU: IDT 79R3041 32bit MIPS RISC processor ROM: 128KBytes in the addresses 0xbfc00000 through to 0xbfc1ffff. The ROM contains the IDT/SIM monitor and I/O routines RAM: 128KBytes in the addresses 0xa0000000 through to 0xa001ffff. The first 64KBytes are reserved for the monitor. The second 64K are used to store and execute programs. A set of Eight switches which can be read from the I/O Controller A Seven Segment Display which can be written to using the I/O Controller Two Serial ports are present on the right hand side of the board. A parallel port is also present internally on the right side of the board. A third serial port (Aux.1) is present in the form of solder pads only. 3. Serial Ports --------------------- The boards console runs on Serial Port A (DB9F). Serial Port A is already crossed over so a STRAIGHT THROUGH serial cable is required. A Null Modem cable will not work at all. Serial Port B is a DB25F port. 4. Other Connectors --------------------- SW1 is the Reset button, S2 is where eight switches attach. Going by the layout overlay on the boards case, J3 is most likely the parallel port. 5. Documentation --------------------- Documentation for the IDT 79R3041 CPU can be found in the ./79R3041 subdirectory on this server. 6. Monitor --------------------- My board uses IDT System Integration Manager v5.1 for its monitor. It reports itself as being the following when powered on: _______________________________ ***************************************************************** * * * IDT System Integration Manager Ver. 5.1 July, 1994 * * Copyright 1992, 1993, 1994 Integrated Device Technology, Inc. * * Modified for use at the University of Waikato 1996 v1.0b * * * ***************************************************************** _______________________________ A list of commands can be obtained using the "help" command.
