User Guides:
Amstrad PLC encourages distribution of the original User Guides for many of the machines they hold copyrights for. This is very welcome, and ensures that the Sinclair community is well served where official documentation is concerned.

Reference Documents:
A small selection of reference documents are available. You may want to refer to these when reading other sections of this FAQ, particularly the ports, pinouts, hardware and Timex sections.

Service Manuals:
If you need to repair a Sinclair machine, or are interested in learning more about how the systems are designed and constructed, the following Service Manuals may be of use to you. Since it is possible to damage your machine by attempting a repair, and can be dangerous if you do not follow the saftey precations, please do not attempt any repairs if you are unsure of your ability to complete them. Several companies offer a repair service and may be able to service your machine for you at reasonable cost.
