Amstrad PLC are very supportive of the Sinclair community
and have granted permission for much of the original documentation to be published and freely distributed. In addition,
many other companies have expressed no concerns about their manuals, etc. being made publicly available. The following is
a short list of the most commonly requested, with many additional items being available from most of these sites.
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.
- Z80 Family Official Support Page
Gaby Chaudry maintains a very large site filled with probably as much information as
you could ever need about the Z80 (and related) processors - FAQ & hardware documents, developer tools and utilities, project source code, etc.
- Timex TS2068 Technical Manual
Based on the original 'blue manual' published by Timex in 1984, this book was produced by Time Designs Magazine in 1986.
This .pdf version was produced by Alvin Albrecht, and is one of the few techincal references available for this machine.
- Rotronics Wafadrive Command Summary
The original User Manual for the Wafadrive is believed to be missing, with no online copy having been produced or made
widely available. However, the 'Command Summary' documentation has been converted to HTML format by
Geoff Wearmouth (see the links page) and is available from
Classic 8-Bit Computers.
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.
