Safety & Warnings

This equipment has been certified to comply with the limits for a Class B computing device, pursuant to Subpart J of Part 15 of FCC Rules. Only computers certified to comply with the Class B limits may be attached to this equipment. Operation with non-certified computers is likely to result in interference to radio and TV reception.

This equipment uses radio frequency energy for its operation; if it is not installed and used properly, in strict accordance with the instruction manual, it may cause interference to radio and television reception. It has been type tested and found to comply with the RF emission limits for a Class B computing device, intended to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

If this equipment does cause interference to radio and television reception, which can be determined by turning the equipment off and on, try to correct the interference by one or more of the following measures:
– Move the computing device away from the receiver being interfered with.
– Relocate the computing device with respect to the receiver.
– Reorient the receiving antenna.
– Plug the computing device into a different AC outlet so that the computing device and receiver are on different branch circuits.
– Disconnect and remove any experimental connecting leads and/or I/O cables that are not being used. (Unterminated leads and/or I/O cables are a potential source of high RF emission levels.)
– Unplug and remove any experimental circuits that are not being used.
– Obtain results of the experiment as quickly as possible, then turn the computing device off.
– Be certain that the computing devices are plugged into grounded outlet receptacles. (Avoid using AC cheater plugs. Lifting of the power cord ground may increase RF emission levels and may also present a lethal shock hazard to the user.)

NOTE: In order to meet Class B emission limits, the user must comply with the following requirements:
– The I/O cables that interconnect between this computer and any peripheral (such as a printer, modem, etc.) must be shielded.
– The line (power) cord shipped with the computer is shielded. If you replace the line cord, be sure to use only a shielded line cord.

If additional help is needed, consult your dealer or ask for assistance from the manufacturer. Customer service information is on the inside back cover of this Manual or on an insert sheet supplied with this equipment. You may also find the following booklet helpful: “How to Identify and Resolve Radio-TV Interference Problems.” This booklet is available from the US Government Printing Office, Washington, D.C. 20402, Stock No. 004-000-00345-4.

Overview

The Heathkit ETW-3800 Microprocessor Trainer with ETC W6811 CPU Module is an educational development system designed to help users learn and experiment with microprocessor architecture and programming. It provides hands-on experience with the W6811 CPU, allowing students, hobbyists, and engineers to develop, test, and debug assembly language programs in a controlled environment. This trainer is ideal for understanding microprocessor operations, instruction sets, and interfacing techniques.

Main Features and Specifications

• Based on the ETC W6811 8-bit microprocessor CPU module
• Comprehensive front panel with switches and LEDs for input/output control
• Expandable memory and peripheral interface options
• Onboard clock generator for timing and synchronization
• Support for assembly language programming and debugging
• Clear, labeled layout for easy learning and experimentation
• Includes power supply and documentation for setup and operation

Basic Usage and Operation Tips

Begin by powering on the trainer and ensuring all switches are in the default position. Use the front panel switches to input program instructions and data manually. Utilize the LEDs to monitor output and status signals in real-time. Refer to the manual for instruction set details and programming examples. Always reset the CPU module before loading new programs to avoid unexpected behavior. Take advantage of the trainer’s memory expansion capabilities to test more complex applications.

Troubleshooting and Maintenance

If the trainer does not power on, verify the power supply connections and check for blown fuses. For erratic behavior, confirm that all switches and jumpers are correctly set according to the manual. Clean the front panel and connectors regularly to prevent dust buildup that can cause poor contact. If LEDs fail to light or switches are unresponsive, inspect for loose wiring or damaged components. Always handle the CPU module with care to avoid static discharge damage.

Safety Reminder

Always operate the Heathkit ETW-3800 Microprocessor Trainer in a dry, well-ventilated area away from flammable materials. Disconnect power before performing any maintenance or hardware modifications. Avoid touching circuit components while the unit is powered to prevent electric shock or damage. Follow all safety instructions provided in the manual to ensure safe and effective use of the equipment.
