AM-642 Fintec STOP Converter
INTRODUCTION
This document describes the installation of an AM-642 FPS STOP (SCSI-to-Pertec) Converter into an
existing Alpha Micro Computer System.
If you do not feel comfortable performing the hardware and software procedures discussed below, please
contact your Alpha Micro dealer or the Alpha Micro Technical Assistance Center for help.
PRODUCT DESCRIPTION
The FPS STOP Converter allows you to connect a ½" magnetic tape drive to the SCSI bus and copy files
to and from it using the standard MTUxxx commands. It is available in two forms:
• PDB-00642-00: an external subsystem which plugs into your computer's external SCSI port. For
additional information about the externally connected AM-642 subsystem, please see the
Installation Manual included with the STOP Converter.
• PDB-00642-01: an assembly which mounts in the card cage inside an AM-990 chassis, attaching
to the SCSI bus via the internal SCSI cable and to the ½" tape drive via cables running out the
computer's back panel.
SCSI Bus Types
Over the years, Alpha Micro computers have offered three different "SCSI" busses. We refer to them as
follows:
1. The bus in AM-2000/3000 and other older computers, which supports up to four SCSI devices, is
the "SASI bus."
2. The SCSI bus in Eagles, Roadrunners, the AM-4000, and newer computers, which requires a
SCSI dispatcher and supports up to seven devices, is the "SCSI-2 bus."
3. The enhanced Wide SCSI-2 bus introduced on the AM-6000 and Roadrunner 060 is the "Wide
SCSI-2 bus." This bus supports up to 15 devices. Note that the cables and 68-pin connectors used
with the Wide SCSI-2 bus are physically narrower than previous SCSI cables
The AM-642 is supported only on the SCSI-2 and Wide SCSI-2 busses. It does not work on the SASI
bus.

    2. If necessary, remove the internal SCSI cable and replace it with the new one provided. 3. Slide the AM-642 assembly into the card cage and attach it to the new SCSI cable. 4. Route the cables from the AM-642 out the I/O panel to the tape drive.
  • Page 3 Installing the AM-642 1. Before inserting the AM-642 into the card cage, be sure to set its SCSI ID. To do so, use the dip switches at SW1, positions 6, 7, and 8. In the following diagram, “On” is toward the center of the AM-642 board.
  • Page 4 5. Reattach the I/O panel to the AM-990 chassis. 6. Route the two cables into the card cage and over the AM-642. Plug the left cable into J2 on the AM-642; plug the right cable into J1. Make sure the red stripe on each cable is properly matched to pin 1 on its connector.

  • Page 5: Scsi Bus Termination

    Narrow Bus Termination On the narrow SCSI 2 bus, terminating the bus at the AM-642 is simple. If the AM-642 is the last device on the bus, you merely plug the terminator supplied with the STOP converter into its terminator port.

  • Page 6: Software Information

    Electrical Power For reliable operation, the AM-642 should be plugged into the same power source as the computer it is attached to. Do not plug it into a separate power circuit.

  • Page 7: Modifying The System Initialization Command File

    Page 7 Modifying the System Initialization Command File To define the AM-642 to your computer, use the COPY command to make a copy of your system initialization command file, calling it TEST.INI. Then edit that copy using the AlphaVUE text editor, making the modifications discussed in the following sections.

  • Page 8: Initial System Testing

    Installation Instructions: AM-642 STOP Converter Testing the Initialization File When you have finished editing the TEST.INI file, and the AM-642 is properly attached to the computer, press the key and type F at AlphaVUE command level to exit. Then log into OPR: (make sure everyone is off your system) and use MONTST to test the TEST.INI file.
  • Page 9 Installation Instructions: AM-642 STOP Converter Page 9 Another useful document is your System Commands Reference Manual. In it you will find reference sheets for the AMOS system software programs and commands mentioned in this document. Also, see your System Operator's Guide for a wide variety of system information and the System Operator’s Guide to the System Initialization Command File for information about system initialization configuration.
