Legacy Module Documentation

This page will host a growing collection of User Guides, User Manual and Builder's Guides for a range of Oakley modules that are no longer produced.

Please be aware that this is not an exhaustive list, nor does it contain schematics for the most part. However, I will endeavour to make all non schematic documents available as time allows. Those schematics that are not listed here are still available direct from me for 2GBP each.

Note: The documents presented here are, by their nature, legacy products and as such they may contain information that is now out of date or incorrect. This is particularly true of any references to pricing, component sources, company addresses and any other contact information.
